benvenuti al trentesimo Congresso, che grazie anche
alla vostra sempre più numerosa partecipazione è divenuto una tappa fondamentale nel panorama protesico internazionale.
Organizzare un Congresso così importante è una grande responsabilità, è doveroso offrire a chi partecipa
un’offerta formativa valida e utilizzabile nella pratica
clinica da tutti i componenti del team protesico e da
ogni operatore che nella propria branca specialistica
si interfacci con l’odontoiatria protesica, terreno sempre più ampio e multidisciplinare, in tumultuosa evoluzione tecnica e scientifica.
Per queste ragioni abbiamo idealmente programmato
il trentesimo Congresso come un anello di congiunzione tra il futuro, che in realtà è già presente, denso di
cambiamenti e novità tecnologiche, merceologiche e
scientifiche, ed il passato, pur presente anch’esso nei
nostri pazienti e nei principi fondamentali che regolano la biologia, la biomeccanica e le relazioni umane
tra professionisti e con i pazienti.
Per questo abbiamo strutturato un programma che rivisiti i “fondamentali” della terapia protesica nelle sue
interazioni con le altre discipline odontoiatriche: endodonzia preprotesica, ricostruzione dei pilastri, trattamento delle zone edentule, rapporti perioprotesici e
rali, dedicati agli igienisti, alle assistenti di studio, alla
protesi totale e alle tecnologie digitali, avremo infatti
una novità: Digital Dentistry@AIOP, l’odontoiatria digitale infatti è entrata ormai a far parte della quotidianità
di ognuno e l’Accademia le dedicherà una sessione apposita.
Sinergie non solo interprofessionali ma anche con le
istituzioni: la sessione di ricerca è sempre più ricca di
apporti provenienti dalle sedi universitarie, italiane e
straniere, all’insegna del necessario ed auspicabile interscambio tra l’eccellenza clinica e la ricerca scientifica, e ne è testimonianza la grande partecipazione al
Premio che l’AIOP dedica al Prof. Mario Martignoni.
Lieti di avervi ospiti nel nostro Congresso festeggeremo
insieme i 150 anni dell’Unità d’Italia, unendo l’anniversario alla ricorrenza della trentesima edizione del Congresso Internazionale.
La cerimonia si svolgerà all’apertura dell’ultima giornata dei lavori congressuali sabato 19 Novembre, e
sarà una sorpresa per tutti.
l’Accademia
con l’implantologia per la sessione odontoiatrica, che
sarà gestita in modo che ogni relatore risponda a domande precise che scaturiscono dalla realtà clinica;
seguirà la discussione, guidata dai “Controrelatori”,
clinici esperti nelle diverse specialità, che sarà certamente un momento dinamico e ricco di spunti per tutti.
La figura del Controrelatore sarà presente anche nella
Sessione Odontotecnica, organizzata come un Corso
di aggiornamento di un intero giorno, che certamente
sarà molto vivace e gratificante per i partecipanti. I primi tre classificati del Premio Polcan, testimonianza della qualità dell’odontotecnica italiana, presenteranno
personalmente il proprio materiale alla fine di questa
sessione.
Il sabato clinici e odontotecnici saranno insieme per la
sessione comune che ribadisce un principio fondante
per lo spirito dell’AIOP: la complementarietà e la sinergica collaborazione tra le due figure protagoniste, assieme ai pazienti, del risultato protesico soprattutto in
ambito estetico e nelle grandi raibilitazioni, dove la comunicazione tra clinico e odontotecnico è indispensabile per la fluidità delle procedure e per la qualità del
risultato, dalla progettazione all’esecuzione.
Sinergie e multidisciplinarietà sotto ogni punto di vista:
dal corso precongressuale, che mostrerà l’organizzazione del lavoro di team in implantoprotesi ai massimi
livelli qualitativi, per continuare con gli eventi collate-
Benvenuti a Bologna!

Corso di Aggiornamento precongressuale
Giovedì 17 Novembre
Sala Europa
Si parla molto di team work, ed è ormai nozione
comune che il lavoro di squadra in implantoprotesi
(ed in protesi in generale…) sia una necessità
assoluta, particolarmente nei casi complessi, per
arrivare ad una soluzione che concili felicemente
qualità, tempi operativi, prognosi e risorse
economiche e fisiche del paziente e del team ma…
è sufficiente lavorare in team per avere ottimi
risultati?
La domanda non è retorica, il team work in
implantoprotesi presuppone un’organizzazione
rigorosa, una condivisione dello studio del caso
e degli obiettivi della terapia ed una attenta
pianificazione operativa. Tutti questi aspetti
verranno partecipati con la platea da una squadra
di Relatori che in maniera quasi pionieristica
ha affrontato dal suo nascere l’implantoprotesi
con questo approccio, anticipando i concetti
di implantologia protesicamente guidata ed
8
utilizzando gli impianti non come “virtuosismo”
chirurgico ma come supporto restaurativo a fini
protesici, dunque mantenendo la centralità del
piano di trattamento protesico a partire dalla
progettazione per terminare con l’esecuzione
tecnica che assicuri al paziente estetica e funzione
ottimali. Strategie, tecniche e mezzi di verifica
saranno oggetto di una giornata che, siamo certi,
arricchirà il patrimonio culturale ed operativo di
clinici ed odontotecnici, offrendo nuovi spunti di
riflessione in merito al concetto di implantologia
protesicamente guidata.

Ridefinizione delle procedure chirurgico/protesiche
nel platform switching
Surgical and prosthetic procedure
re-organization to exploit platform switching
Relatore: Dott. Luigi Canullo
Speaker: Dr. Luigi Canullo
La revisione della Letteratura sulla tecnica del Platform Switching
ha ormai permesso di validarne la scientificità, dimostrando gli
aspetti biologici che sottostanno al comportamento clinico. Infatti,
i risultati clinici e radiografici a lungo termine hanno confermato
che l’applicazione di questa modalità restaurativa permette di
ridurre il riassorbimento osseo peri-implantare. Studi istologici
hanno recentemente permesso di comprendere meglio il perché di
una così positiva risposta tissutale: una differente disposizione della
componente connettivale della cosiddetta “ampiezza biologica”
nella sua fase di formazione, consentirebbe infatti una più stabile
protezione dell’osso sottostante.
Sulla scorta di queste conoscenze biologiche e allo scopo
di rendere più efficaci e duraturi gli effetti del Platform
Switching si è sviluppato anche un nuovo protocollo protesico,
definito “minimamente invasivo”. Tale protocollo consiste
fondamentalmente nel ridurre al minimo il numero delle
disconnessioni del complesso abutment/impianto minimizzando i
danni alla componente connettivale e prevenendo così la crescita
apicale dell’epitelio e il conseguente riassorbimento osseo.
Inoltre, l’adozione di conformazioni non standard del complesso
corona/abutment sembrerebbe aiutare il clinico ad ottenere una
risposta adattativa dei tessuti molli in grado di fornire risultati
molto positivi nel tempo, specialmente nei casi ad alta valenza
estetica, senza adottare procedure chirurgiche aggiuntive come
gli innesti connettivali.
Literature revision allows to demonstrate the background of the
platform switching, investigating the biologic concept behind the
clinic behavior. In fact, clinical and radiographic long term results
demonstrated that this concept is applicable to reduce peri-implant
bone remodeling. Histological experiments allowed to clarify the
reason of such a positive tissue response: a different disposition of
the connective component of the so called “biologic width” allows a
walling-off function on the underlying hard tissues.
Analyzing this histologic aspect, to fully exploit potential positive
behavior of platform switching, a new “minimally invasive”
prosthetic approach can be adopted. Such protocol is based on
reducing dis/re-connection of the implant/abutment complex and
allows to reduce the micro-damages to the connective component,
preventing the epithelial down-growth and bone resorption.
According to this paradigmatic assumption, non-standard crown/
abutment complex can be adopted to obtain an adaptive soft tissue
response, treating highly demanding aesthetical cases, minimizing
the surgical impact on patients and fitting their expectations.

TC e diagnostica 3D al servizio del Team
Odontoiatrico
CT and 3D diagnostic system to serve
the dental team
Relatore: Dott. Christian Monti
Speaker: Dr. Christian Monti
Viviamo e lavoriamo in un’epoca di continui cambiamenti, la
ricerca tecnologica e la relativa proposta di prodotti, avanzano
a ritmi vertiginosi, e talvolta non riusciamo a stare al passo con le
innovazioni.
Oggi il digitale la fa da padrone, e le aziende che lo propongono
entrano a far parte dei nostri team di lavoro, sostituendo figure
fondamentali dello stesso.
Il nostro obiettivo è quello di guardare al futuro senza perdere di
vista ciò che ci ha guidato fino ad ora, per questo proponiamo
un sistema semplice, analogico e digitale, che consente di fare
diagnosi, di approntare piani di trattamento e di sviluppare
protocolli implanto-protesici, mantenendo la centralità del Team
Odontoiatrico.
Grande attenzione verrà inoltre posta alla valenza comunicativa di
cui dispone il nuovo software diagnostico
ONE SCAN 3D.
We live and work in a period of constant changes, technological
research and its proposed products, are advancing at a dizzying
rate, and sometimes can not keep up with innovations.
Today, digital is king, and the companies that offer it become part
of our team, replacing key figures of the same.
Our goal is to look to the future without losing sight of what has
guided us until today and that is why we propose a simple system,
analogic and digital, which allows to diagnose, to prepare
treatment plans and implant-prosthesis protocols, maintaining the
centrality of the dental team.
Great attention will be given to the communicative value of the new
diagnostic software ONE SCAN 3D.

I FONDAMENTALI DEL PILASTRO
PROTESICO: ASPETTI ENDODONTICI,
RICOSTRUTTIVI E PARODONTALI
La frequenza con la quale il pilastro protesico è un
elemento vitale e strutturalmente integro risulta sempre
minore, grazie all’affidabilità e alla diffusione delle
soluzioni implantari. Esistono, per contro, diverse
situazioni in cui elementi dentari compromessi entrano
nel piano di trattamento protesico per motivazioni varie,
e per i quali deve essere garantita l’affidabilità nel tempo.
Durante questa sessione verranno esaminati i requisiti
fondamentali endodontici, ricostruttivi e parodontali
necessari per condizionare positivamente il successo a
lungo termine.

I fondamentali dell’estetica in protesi: pilastri implantari
e zone eduntule
Anche in assenza del parodonto il trattamento dei
tessuti molli rappresenta una tappa cruciale per
il raggiungimento di un risultato estetico ottimale.
L’interazione fra le competenze chirurgiche e quelle
protesiche è determinante per coniugare l’integrazione
tissutale dei restauri con una prognosi favorevole.
Cosa può fare il chirurgo per creare un “ambiente”
favorevole al protesista? E cosa può fare il protesista per
condizionarlo e mantenerlo?

il rapporto fra odontoiatra ed odontotecnico è naturale
in protesi, troppo spesso viene dimenticato il paziente,
fruitore finale di ogni nostra terapia.
Con quali strumenti il paziente può essere coinvolto
nella spiegazione del piano di trattamento? Quali
invece gli strumenti di comunicazione fra dentista
ed odontotecnico nella formulazione del piano di
trattamento? E quali nella fase di realizzazione? A queste
domande verrà data risposta nel corso di questa sessione
in riferimento alle riabilitazioni totali e dei settori estetici.

AIOP e ICP
La nostra Accademia è associata all’INTERNATIONAL FEDERATION of ESTHETIC DENTISTRY (IFED), un’organizzazione nata nel
1994 per iniziativa dell’Accademia Americana di Odontoiatria Estetica, dell’Accademia Europea di Odontoiatria Estetica
e dell’Accademia Giapponese di Odontoiatria Estetica. Fanno
parte di questa organizzazione società dentali che si occupano
di odontoiatria estetica: l’AIOP è l’unica Società Scientifica italiana riconosciuta dall’IFED quale rappresentante dell’estetica in
campo dentale. Gli altri membri dell’IFED, sono:
L’International College of Prosthodontists (ICP) è un’organizzazione internazionale che è stata fondata nel 1982 per iniziativa
dell’American College of Proshodontists e di un gruppo di protesisti provenienti da diversi paesi: Svezia (Bo Bergman), Australia
(Lloyd Crawford), U.K. (il compianto Rowland Fereday, William
Murphy, Harold Preiskel), Giappone (Makoto Matsumoto), U.S.A.
(Jack Preston), Svizzera (Peter Scharer), e Canada (George Zarb).
L’ICP ha come obiettivo principale quello di promuovere l’attività
protesica e di diffondere e rafforzare la figura professionale del
protesista come specialista. L’AIOP fa parte dell’ICP quale rappresentante italiano della specialità. Le altre Associazioni membre dell’ICP sono: Academy of Australian and New Zealand Prosthodontists, Academy of Prosthodontics of South Africa, American
College of Prosthodontists, Association of Prosthodontists of Canada, Chinese Prosthodontic Society, Israeli Society of Prosthodontics e Korean Academy of Prosthodontics. È possibile associarsi
anche in modo individuale secondo le modalità esposte nel sito
www.icp-org.com.
Ogni due anni l’ICP organizza un congresso internazionale;
quest’anno si è tenuto a Big Island (Hawaii) il quattordicesimo
congresso. L’attenzione del comitato organizzativo è rivolta alle
tante novità tecnologiche ed alla necessità di riformare la figura
del protesista in modo che l’aspetto biologico acquisti sempre
maggior attenzione. L’attività del protesista, infatti, si occupa
della riabilitazione orale all’interno di un quadro biologico dove
la qualità delle tecniche e dei materiali hanno un forte impatto
sulle risposte biologiche sulla salute dei tessuti orali.

Preprosthetic Surgery and Implant Surgery
Objectives: The aim of this study is to investigate the in vivo efficacy
of Puros® cancellous particulate allograft bone (Zimmer dental®) in
the regeneration of the post-extractive sites
Methods: 10 molar or premolar sites (8 patients) with teeth to be extracted were selected. A minimally invasive extraction of the teeth
was performed. The following day the patients underwent a TC Cone-Beam investigation only at the level of post-extractive sites to evaluate height and thickness of alveolar sockets. 7 days after the extraction, Puros® cancellous particulate allograft were inserted into
the elected sites together with a membrane (CopiOs® Zimmer Dental®). After 4 months, a TC Cone-Beam of the sites was performed to
quantitatively assess actually gained bone thickness. After 5 months,
samples of the regenerated sites were taken thanks to bone drills
(Trephine Bur 2mm ID 3 mm ED, Biomet 3i®) and an implant was
contextually inserted in each regenerated site. The samples were
histologically analyzed to qualitatively evaluate bone regeneration
Results: The Tc analysis of the 10 sites (upper jaw: 6; lower jaw: 4)
highlighted, in height, a mean bone gain of 4.1 mm in the lower
jaw (range 5-1,9 mm; alveolar walls mean height after extraction =
7.6 mm, 4 months later = 11.7 mm) and 3.35 mm in the upper jaw
(range 4-2,3 mm; alveolar walls mean height after extraction = 4.87
mm, 4 months later = 8.22 mm). In width, a mean bone gain of 2.02
mm in the lower jaw (range 2.8-1.5 mm; alveolar walls mean width
after extraction = 6,32 mm, 4 months later = 8.34 mm) and 2.15 mm
in the upper jaw (range 2.8-1.6 mm; alveolar walls mean width after
extraction = 6,9 mm, 4 months later = 9.05 mm). The SEM analysis of
the samples showed an intense bone metabolic activity with active
osteoblasts both on the implant surface and at the level of the native
bone-graft interface, and in the grafted area. The grafted material
was partially replaced by new regenerated bone and a partially
mineralized osteoid matrix was visible with new vessels: the matrix
produced was going to be organized in a more mature tissue
Conclusions: This study establish a scientifically reliable method to
study bone regeneration in post extractive-sites. The radiographic
and histological analyses underline an optimal bone regeneration,
both in terms of quality and quantity using Puros®. Additional studies are needed, involving a greater number of patients and comparative graft materials to validate the use of this material

Oral and Maxillo-Facial Prosthesis
Objectives: Patients undergoing demolition for oncological reasons
can receive no reconstruction or be treated with local or vascularized flaps. The reconstructive choice limits the prosthetic one and
it would be desirable to plan appropriate rehabilitative therapy
before surgery, but urgency and radicality do not often allow preoperative prosthetic programs. Goal of this work is to illustrate the
clinical variations that may occur, to expose available possibilities of
rehabilitation and reasons that drive clinical choices
Methods: By analyzing the literature from 1995 to 2010,20 items, related to the prosthetic rehabilitation of oncological patients, were
selected; from the performed review, only 4 authors reported systematic data on the rehabilitation which was carried out in relation
with the surgery and the anatomical region treated. Analyzing 30
cases, managed at our institution on the basis of knowledge gained,
15 were treated for tumors of the mandible, of which 20% with fixed
prostheses on implants and 15 tumors of maxilla, of which 30% with
fixed prosthesis on implants, remaining patients were rehabilitated
with removable dentures
Results: The rehabilitative choice must take account of certain key

elements such as the tumor histology, the type of surgery, the extent
of demolition, the kind of radio and chemo-therapy, the condition
of peri-and intra - oral soft tissues and the possibility of further treatments. The results of this research show that the most commonly
used devices to rehabilitate a post-oncological patient are anchored overdenture implant retained for the mandible and removable
dentures for the maxilla. Discussing and explaining the treatment
options we show three exemplary cases: a patient rehabilitated with
removable dentures, a patient rehabilitated with mobile prostheses
anchored on telescopic crowns and finally a patient rehabilitated
with fixed prostheses on implants
Conclusions: Every oncological patient can and must aspire to restore chewing function and esthetic results. This is possible by choosing for each case the appropriate technique. At this purpose, the
research must try to use an universal language for classification
standardizing the many and articulated treatments

tact angle for 3 different sesile drops. The measurement system was
set to read 20 contact angle values, at 1 second interval, exposing
the dynamic nature of the phenomenon. The statistical analysis was
performed with SPSS for Windows, v.10.0.1
Results: Artificial saliva wetts the resin 42% better than natural saliva. Eco-cryl-hot is most wettable with natural saliva (70,59º), while
Polyan presents la lowest contact angle with artificial saliva (41,06º).
Polyan, BMS 014 and Superacryl present the biggest differences (46º)
between mean contact angles for artifical and natural saliva
Conclusions: In the condition of the current in vitro experiment, artificial saliva seems to be more efective for the xerostomic denture
wearer, while the measurements for the injection type are less variable, indicating a uniform surface. Further improvement of acrylic
surface could improve the condition of xerostomic patient

Objectives: The aim of our study was to evaluate the functional benefit of using magnets as secondary attachments on remained molars used as auxiliary abutments for the removable partial denture
and also to assess the patient’s satisfaction regarding these prosthetic solution
Methods: In this study we analyzed only removable partial dentures with extra-coronal ball attachments on the main abutments
and magnets on the auxiliary ones. We selected edentulous patients
in imminence of becoming class I or II Kennedy, but we choose to
keep some of the periodontally affected last molars under the terminal saddles. The surveying period was of 4 years and it included 12
patients, 6 males and 6 females. The variables studied were: class
of edentulism, number of magnets we used in each case and the
opposing arch situation. The study was centered on the patient’s
satisfaction regarding chewing ability, retention and stability of the
dentures
Results: Patient’s satisfaction concerning chewing ability, retention
and stabilization of the denture was highly superior in presence of
the molars with magnets under the free-end saddles then in their
absence. The use of magnets presented various difficulties in different clinical situations
UMF Carol Davila Bucharest ~ UMF Carol Davila Bucharest
Objectives: The succesfull complete denture therapy could benefit,
in case of xerostomic patient, from studies on wettability of denture
base materials with natural or artificial saliva. This in vitro investigation represents a starting point for the use of different methods
to improve the hydrophilicity of denture-saliva system, which could
increase the quality of life for the xerostomic pactient. Our objective
is the evaluation of 4 moulding-type and 1 injection type denture
base resins regarding their wetting capabilities with natural and
artificial saliva
Methods: Six unpolished plates of PMMA resin were produced by
different labs. The first lab used Eco-Cryl-Hot (Protechno, Spain) and
Acry-Pol-R (Ruthinium, Germany), while the second lab utilized BMS
014 (BMS Dental, Italy) and Superacryl (Spofa, Czech Republic). Two
different labs produced each one plate of Polyan (Bredent, Germany). The plates were cut in 10x10mm samples. Wettability was
expressd after the measurement of the contact angle of unstimulated natural saliva and artificial saliva (Xerostom, Biocosmetics Laboratoires, Spain). The measurement was performed using CAM 101
system (KSV Intruments, Finland) which calculated the mean con-
Conclusions: Conclusions: Magnets are relatively easy to use and
to fit in various clinical situations. They are well accepted by the patients because they are significantly increasing their chewing ability
and the retention and stabilization of their removable partial denture. Teeth that suffer from moderate periodontal disease with concomitant bone loss can be used as abutments if the initial design of
the denture is made in such manner that the loss of these auxiliary
abutments does not imply the loss of the denture

assessed by determining the Plaque Index, Gingival Index, Margin
Index and pocket depth of the abutment and control teeth. Statistical analysis was performed by applying Wilcoxon rank sum and
Wilcoxon signed-rank tests
Results: The survival for metal-ceramic restorations was 100%, and
95% for zirconia ones. One biological complication in a zirconia FDP
was observed at the three-year follow-up. No fractures of the zirconia or metal frameworks were observed. Restorations from both
groups were assessed as satisfactory. Minor chipping of the veneering ceramic was observed in two (11%) of the zirconia FDPs. No
significant differences were observed between the abutment and
the contralateral teeth for either type of restoration as well as within
the groups, as regards PI, GI or pocket depth
Conclusions: Zirconia-based FDPs demonstrated a similar success
rate to metal-ceramic FDPs after medium-term clinical use
Universidad Complutense ~ Madrid

Objectives: The aim of the present study was to compare the survival rates and biological and technical complications of 3-unit metal-ceramic posterior FDPs with those obtained when using the Lava
system. The null hypothesis was that no differences would be found
between the parameters studied for each type of restoration
Methods: 37 patients in need of 40 3-unit posterior FDPs were included in the study. The FDPs were randomly assigned to 20 zirconia and 20 metal-ceramic restorations. Abutment preparation
was performed as follows: a circumferentially chamfer (1 mm in
width), an axial reduction of 1 mm, and an occlusal reduction of
1.5-2 mm. The tapering angle was 10-12 degrees. After preparation,
full-arch impressions were taken using addition silicone (Express
Penta Putty and Express Penta Ultra-Light Body; 3M ESPE) and the
double-impression technique. Provisional restorations (Protemp Garant; 3M ESPE) were then made and cemented using a temporary
eugenol-free zinc oxide cement. (Integrity TempGrip; Dentsply De
Trey GmbH). The ceramic restorations were prepared using a Lava
(3M ESPE) CAD/CAM system and the metal-ceramic ones were fabricated from a Cr-Co alloy (Heraenium Pw, Heraeus Kulzer) using the
conventional casting technique. The ceramic FDPs were cemented
using a resin-based cement (Rely X Unicem; 3M ESPE) and the metalceramic ones with a glass ionomer cement (Ketac Cem, 3M ESPE). At
baseline, and 1, 2, 3 and 4 years after cementation, success of both
types of restorations were evaluated. The restorations were assessed using the CDA’s assessment system Periodontal parameters were

Objectives: The purpose of this study was to evaluate the clinical
performance of In-Ceram Ziconia posterior fixed dental prostheses
(FDPs) after 10 years in service
Methods: Eighteen In-Ceram Zirconia FDPs were inserted in 16 patients. The FDPs were placed between January and April 1999. The
abutment teeth were prepared with a 1.0 mm chamfer finish line,
the occlusal reduction was approximately 2.0 mm and the tapered
angle of about 12 degrees. The preparations margins were placed
at the level of the gingival margin. The impressions were made with
a rigid standard tray with an A-silicone putty soft and light-body
material (Aquasil, Dentsply). No cantilever FDPs were included. The
laboratory procedures were performed by a technician authorized
by the Vita supplier, fabricating the FDPs from model to finished construction in accordance with the instructions of the manufacturer.
The occlusogingival height of the core material connector between crown and pontic was 4 mm. Two types of luting materials were
used, one for each operator. Zinc phosphate cement (Fortex, Faciden S.L.) was used in ten cases and glass-ionomer cement (Ketac

Cem, Espe) in eight cases. The patients were scheduled for a final
evaluation 1 week after cementation, and they were then scheduled for follow-up evaluation annually. Neither of the examiners was
involved in treatment of the patients. The California Dental Association quality evaluation system was used for assessment of surface
and color, anatomic form and marginal integrity. The periodontal
conditions were recorded for the crowned abutment and the contralateral tooth (control)
Results: After 10 years, one of the 18 posterior FDPs was lost because of a root fracture and another one because of fracture at the
distal connector. All remaining FDPs were rated as either excellent
or acceptable after the observation period. No loss of retention or
secondary caries was observed. In two cases (11%) fracture of the
veneering ceramic occurred.The cumulative FDPs success rate after
10 years was 89%. No significant differences were observed between the abutment and contralateral teeth regarding the periodontal
parameters
Conclusions: In-Ceram Zirconia posterior FDPs seem to be an acceptable treatment alternative, in a 10-year perspective to conventional FDPs

Objectives: Marginal fit is a very important factor considering the
restoration’s long-term success. However, adding porcelain to frameworks may cause distortion and lead to an inadequate fit which
exposes more luting material to the oral environment and causes
secondary caries. The aim of this study was to compare the marginal fit of 3-unit zirconia-based fixed dental prostheses (FDPs) before
and after porcelain veneering
Methods: Twenty standardized steel specimens were prepared to
receive posterior 3-unit FDPs. FDPs were fabricated using a yttrium
cation-doped tetragonal zirconia polycrystals all-ceramic system
(IPS e.max ZirCAD, Ivoclar Vivadent) according to the manufacturer’s instructions. The vertical marginal discrepancy of the FDPs was
measured before and after porcelain veneering by using an image
analysis system at 240 points along the circumferential margin. Sta-
tistical analysis was performed by Wilcoxon Rank-Sum Test with the
level of significance chosen at 0.05
Results: The means and standard deviations of the marginal fit
of FPDs were 74.1 ± 26.5 µm before porcelain veneering and 33.6
± 20.2 µm after porcelain veneering. Significant differences were
found when analyzing the marginal gaps before and after porcelain veneering (P=0.0054)
Conclusions: Zirconia-based all-ceramic FPDs showed marginal
gaps that were within a reported clinically acceptable range of
marginal discrepancy. Porcelain veneering showed to have a positive influence on the marginal fit of the all-ceramic FPDs

Objectives: To calculate the percentage of the removed tooth structure during the various complete crown preparations
Methods: Maxillary right first molar resin teeth and basic study model (KaVo Dental) were used for this study. Seven preparation designs for the complete crown restoration were chosen: one (1) for
complete metal ceramic crown MCC (facial: rounded shoulder;
oral: chamfer); three for complete all-ceramic crown (ACC) for zirconia (chamfer (2), shoulder (3) and knife edge finish line (4) ); three for
ACC for lithium disilicate (shoulder (5), chamfer (6) and minimal preparation with small chamfer finish line (7) ). For each preparation
design 10 teeth were prepared. All the plastic teeth were weighted
before and after the preparation using the professional precision
balance Sartorius CP225D. One unprepared tooth was separated
close to CEJ in order to know the weight of the root of the plastic
tooth. For standardization of data, the weight of the prepared coronal part of the tooth was calculated removing the same weight
of the root from every tooth. The percentage of the removed tooth
structure was calculated by formula: RS= 100(Wo-W)/ Wo. The statistic analysis was made using Kruskal and Wallis test (p<0.05)
Results: Statistic analysis hasn’t shown the statistical differences
between all the group except the first. Group 1 (43.49%) was statistically different from group 4 (36.99%) and group 7 (35.33%), p<0.05.

Objectives: The aim of this prospective study was to evaluate the
clinical performance of zirconia based (Lava) posterior 4-unit fixed
partial dentures (FPDs) after 4 years of clinical observation
Methods: Twenty one 4-unit FPDs were placed in 12 patients. Thirteen FPDs were placed in the maxilla and eight in the mandible. Two
calibrated examiners evaluated the FPDs independently 1 week
(baseline), 6, mouths, 1, 2, 3 and 4 years after placement using the
California Dental Association (CDA) quality evaluation system. Periodontal health was assessed on abutment teeth and contralateral
control teeth. Periodontal indices utilized were plaque index, gingival index, probing attachment level, and margin index. Statistical
analysis was performed using descriptive statistics and the Wilcoxon
signed-rank
Results: Three restorations were lost due to fractures in the distal
connector areas after a mean clinical service time of 25.3 months.
Also, one abutment tooth was extracted because of root fracture.
Thus, after 4 years, the survival rate of the Lava posterior 4-units FPDs
was 80.9%. There were no dental carious lesions in the abutments.
Regarding the CDA ratings, the restorations were evaluated as satisfactory. There were no significant differences between the periodontal parameters on the test and control teeth. However, the Löe
and Silness scores demonstrated a slight increase in inflammation
for all areas of the abutments after 4 years
Conclusions: The use of zirconia-based posterior 4-unit FDPs have
to be restricted for cases with high aesthetic demand, provided that
the prosthetic space allows us the use of a connector with at least
4 mm height. Further long-term studies must be performed to establish the advisability of these restorations

Objectives: The aim of this study was to evaluate the clinical performance of zirconia-based (IPS e.Max ZirCAD) posterior 3-unit fixed
dental prostheses (FDPs) versus conventional metal-ceramic FDPs
after 3 years of clinical observation
Methods: Forty 3-unit FDPs were placed in 40 patients (20 for group).
The abutment teeth were prepared with a 1.0 mm chamfer finish
line, and an occlusal reduction of approximately 2.0 mm. The tapering angle between the axial walls was 10-12 degrees. After preparation, full-arch impressions were taken using addition silicone (Express Penta Putty and Express Penta ultra-light body; 3M ESPE) and
the double-impression technique. The FDPs were cemented using a
glass ionomer cement (Ketac Cem, 3M ESPE). Two examiners evaluated the FDPs at baseline, 1, 2 and 3 years after placement using the
California Dental Association quality evaluation system. Periodontal
parameters were assessed at the abutment and control teeth
Results: At the 3 year follow-up, the cumulative survival rate and
cumulative success rate were 100 % for all FPDs. Two of the IPS e.max
Zir-CAD restorations had experienced minor chipping of the ceramic veneer and replacement was not neccesary. There were no
dental carious lesions at the abutments. Regarding the CDA ratings,
the restorations were evaluated as satisfactory for 100% of FDPs at
all examinations. There were no significant differences between the
periodontal parameters on the test and control teeth. The patients
found the esthetics to be excellent in zirconia group
Conclusions: Within the limitations of this study, IPS e-max ZirCAD
system can be a suitable alternative for use in posterior FPDs

ticeable difference of percentage: 2 (41.58%), 3 (42.00%), 5 (42.87%)
and 6 (42.44%). There was also an important clinical difference of
the removed structure position - internal angle of the finish line
Conclusions: The minimal preparation and preparation with knife
edge finish line have shown the smallest amount of removed structure. It is important to considerate that the chamfer finish line is more
conservative than round shoulder finish line and helps to avoid destructive tooth preparations

how the tip is positioned relative to the tooth, thus overcoming the main
disadvantage of traditional ultrasonic instruments during tooth preparation
Methods: Materials and methods Inserts with different granulometries were evaluated: diamond diameter was 120 µm for D120 insert,
90 µm for D90 insert, 60 µm for D60 insert. Premolars extracted for
periodontal disease were prepared with a chamfer design using
the different inserts to be tested. Surface roughness of 5 dental
abutments prepared with D120 insert was analyzed by means of a
rough profile gauge, while surface roughness of 5 dental abutments
prepared with D90 and D60 inserts was analyzed with a roughness
tester (Mitutoyo Surf Test SJ-301). A metallographic microscope
(Reichert-Jung, model MF3) and dedicated software were used to
analyze surface roughness of a dental abutment prepared with D90
insert
Results: Ra values for dental teeth prepared by D120 was 7.79 µm.
Ra and Rz values for dental teeth prepared by D90 were 7.17 µm
and 12.60 µm respectively, while for teeth prepared by D60 insert
they were 6.22 µm and 9.99 µm respectively. Metallographic microscope analysis showed Ra values of 6.92 µm for D90 insert
Conclusions: Conclusion The surface roughness values found in
this investigation are consistent with reported values of ideal roughness for teeth prepared for fixed dental prostheses in dental literature ( Ra 5 µm-12 µm) (Gilde H et al. 1984). The new piezoelectric
tools (Tipholder DB basic insert and the Mectron® Crown prep tips
terminal insert D120, D90, D60) can be considered a valuable alternative to traditional ultrasonic devices for teeth preparation
Objectives: The objective of this 3-year randomized controlled trial
is to compare the longevity and the clinical behaviour of single posterior crowns made with pressable ceramic on zirconia or metal
framework, and if failures occur, to delineate factors contributing
the failures
Methods: 72 patients, (range age from 18 to 70 years), who needed
the covering of at least a molar and/or premolar were included in
the study. All teeth presented absence of pain, active periodontal
and pulpal desease, had an occluso-gingival dimension of at least
3mm and presented at least 1 mm of ferrule effect. 90 single crowns
(45 for the test and 45 for the control group) were made with an
IVOCLARVIVADENT system and consists of zirconia (ZirCAD) or metal
framework (IPS d.sign 91) supplemented by a specially designed veneer ceramic (ZirPress). The framework was fabricated using CAD/
CAM procedures. All single crowns were luted with Unicem. Patients
were recalled at 6, 12, 24, 36 months post-cementation for a followup review of the restorations. This included periapical radiographs,
intraoral photographs, measurement of periodontal parameters
and USPHS modified criteria. Wear of the antagonist tooth and ceramic was tested using a replica technique. Tables of percentages
were prepared to summarize the demographic characteristics of
the patients, the distribution of crowns and the baseline data, and to
illustrate the recall findings. The statistical analysis were performed
with the Kaplan-Mayer method
Results: At 36 months, two chipping of the veneering ceramic occurred in metal-ceramic crowns, one chipping in a Zircad/Zirpress
crown and one fracture of the zirconia core. The Kaplan-Mayer survival probability was 95,5% at 36 months for both all-ceramic and
metal-ceramic crowns
Conclusions: According to the results of this clinical study, zirconia
crowns exhibited suficient strength and represent a valid alternative
for posterior single restorations. The overpressing technique seems
to reduce the occurrence of chipping of the veneering porcelain

Objectives: The aim of this prospective study was to evaluate the
clinical performance of 143 anterior crowns made of NobelProcera
Alumina after 10 years in service
Methods: One hundred forty-three NobelProcera Alumina crowns
were fabricated for 52 patients since 1997 to 2001. Crown placement
involved the anterior maxillary dental arched: 26 upper canines, 62
upper central incisors and 55 upper lateral incisors. All restorations
were cemented with a resin based cement. The California Dental
Association quality evaluation system was used for assessment of the
surface and color, anatomical form and marginal integrity. Followup examinations were conducted at baseline and once a year during 10 years
Results: At 6 months, the cumulative survival rate and cumulative
success rate were 100%, at 5 years were 97% and at 10 years 91%.
Ten crowns had experienced a fracture through the veneering porcelain and the coping material. Three additional crowns were replaced as a result of abutment fractures. Bleeding was somewhat
more often recorded at abutments than the contralateral teeth after
a mean service of 10 years. All remaining crowns were ranked as
either excellent or acceptable for surface/color, anatomic form, and
marginal integrity
Conclusions: Within the limitations of this study, NobelProcera Alumina crowns showed excellent clinical results in esthetical zone, after 10 years of clinical evaluation

Objectives: The aim of this study was to evaluate the vertical misfit
and microleakage of laser-sintered and vacuum-cast cement-retained implant-supported crown structures
Methods: Crown copings were constructed with: 1) laser-sintered
Co-Cr (LS) (ST2724G); 2) vacuum-cast Co-Cr (CC) (Gemium-cn); and
3) vacuum-cast Ni-Cr-Ti (CN) (Tilite). Frameworks were luted onto
machined abutments under constant seating pressure. Each alloy
group was randomly divided into 4 subgroups (n = 12 each) according to the cement system used: 1) Fuji PLUS (FP); 2) Clearfil Esthetic
Cement (CEC); 3) RelyX Unicem (RXU); and 4) DentoTemp (DT). After
30 days of water storage, vertical discrepancy was measured by
SEM, and marginal microleakage was scored using a digital microscope. Misfit data were analyzed by 2-way ANOVA and StudentNewman-Keuls multiple comparison tests. Marginal microleakage
scores were processed by Kruskal-Wallis and Dunn’s tests (a = 0.05)
Results: Alloy/manufacturing technique and luting cement influenced vertical discrepancy (p<0.0001). For each cement type, LS
samples exhibited the best fit (p<0.001) whereas CC and CN frames
were statistically similar. Within each alloy group, CEC and RXU provided comparably greater discrepancies but lower microleakage
scores than FP and DT, which showed no differences
Conclusions: Laser-sintered Co-Cr may be an alternative to
cast base metal alloys to obtain passive-fitting implant-crowns.
Notwithstanding the framework alloy, definitive resin-modified glass
ionomer (FP) and temporary urethane-based (DT) cements demonstrated better marginal fit but superior microleakage than did MDPbased (CEC) and self-adhesive (RXU) dual-cure resinous agents. All
groups presented clinically acceptable misfit values. The possible
correlation between low cement microleakage scores and sealing
capability that may compensate for misfit deserves further investigation

Implant Supported Prosthesis
Objectives: Clinical study to investigate the outcome of full-arch fixed dental restorations supported by immediate loaded axial and
tilted implants, using the ‘one-model technique’. The survival rate of
axial and tilted implants was compared
Methods: Thirty patients (20 females and 10 males) were included in
the study. Six patients received dental implants in the upper and lower
jaw at the same day. A total of 36 arches (20 maxillae and 16 mandibles) were treated with implants. Each arch received a fixed dental
prosthesis screw-retained over axial or axial and tilted implants within
24 hours from the surgery. A total of 202 implants (118 in the maxilla and
84 in the mandible) were placed. Patients were scheduled for followup at 6, 12, 18, 24 months, and annually up to 7 years. Plaque level
and bleeding scores were assessed after 3 months and 1 year of loading; moreover, patient’s satisfaction for function and aesthetics were
evaluated by a questionnaire. Radiographic evaluation for marginal
bone level change was performed at 1 year
Results: Patient follow up ranged from 15 to 67 months (mean 40
months). 43% of the implants were evaluated at the 4-year recall.
Four axial implants were lost in three patients, leading to 98.02% implant (98.8% in the mandible and 97.46% in the maxilla) and 100%
prosthetic cumulative survival rate, respectively. Plaque and bleeding indexes showed decrease over time, parallel to increase of satisfaction for both function and aesthetics. No significant difference
in marginal bone loss was found between tilted and axial implants
at 1-year evaluation
Conclusions: Within the limitations of this study, the mid-term results
confirm that immediate loading of axial and tilted implants provide a viable treatment modality for the rehabilitation of edentulous
arches

Objectives: The aim of this study was to assess the outcomes of prosthodontic rehabilitations with implant overdentures at a 5-year recall
Methods: Edentulous subjects treated with implant maxillary or
mandibular overdentures during 2005 were recalled for a thorough examination; 12 patients (53 fixtures) could be enrolled. The
analysis involved thirteen overdentures. At the 5-year recall, periimplant parameters were recorded by using the following indexes:
plaque index (PI), bleeding index (BI), gingival index (GI), probing
pocket depth (PD). One questionnaire (Q1) was used to assess general satisfaction with the prosthesis, comfort, ability to speak, retention and stability, ability to chew hard and soft food; the ratings
were obtained on a 0-10 Likert scale. Patients were also asked to
answer four additional closed-ended (Yes/No) questions, on another
form (Q2), specifically oriented to the treatment experience. Means
of the clinical parameters were calculated and a statistical analysis
was accomplished to detect differences between mandibular and
maxillary peri-implant health (ANOVA test, a=0.05); means of the ratings for Q1 were calculated, while descriptive statistics (frequency
distribution analysis) was performed for Q2
Results: Overall survival rates for implants was 98,11%: one mandibular fixture (1/53) failed. All examined maxillary and mandibular
overdentures were still in function at 5 year recall, with survival rate
of 100%. Mean probing pocket depth (PD) of the peri-implant mucosa was 3,02 mm (S.D. ± 1,70), with no significant differences between maxillary (3,16 mm ± 1,69) or mandibular fixtures (2,89 ± 1,72).
Mean score values (range: 0 - 3) of the recorded clinical parameters
were: PI = 1,38 ±0,87; GI = 0,77 ± 0,73; BI = 1,38 ± 0,87. Ratings for
the answers of questionnaire Q1 were >= 9 for all investigated area
of patient satisfaction, with few or no functional problems (chewing
or speaking); the main reported concern was food retention under
the prosthesis. In Q2, 83% of respondents would recommend an
implant overdenture rehabilitation to friends with a similar pre-treatment condition
Conclusions: Within the limitations of our study, high survival rates

Objectives: The objective of this randomized clinical trial is to evaluate the aesthetic outcome (perceived by clinician and patient) of
dental implant abutments of different materials (zirconium oxide vs
titanium)
Methods: 30 healthy patients were selected in the periodontal department of the Complutense University of Madrid (Spain) and were
randomly assigned to the intervention or control group. Every patient
received a single maxillary implant (Thommen SPI®). After 4 months,
all implants were successfully osseointegrated (mean RFA 74.4±7.9).
Patients were randomly allocated to receive a zirconia abutment
(test group) or a titanium abutment (control group) for prosthetic restoration. Randomization was computer-generated, with allocation
concealment by opaque sequentially numbered sealed envelopes.
The primary outcome variable was the Implant Crown Esthetic Index (ICAI), whereas secondary outcomes were patient’s expectation,
papilla index, clinical and radiographic measurement. Patient, surgeon and investigator who perform outcome assessment and data
analysis were blinded to group assignment
Results: After implant placement, 15 patients were allocated to each
group. At present, 24 patients (11 test and 13 control) completed the
prosthetic phase, and were included into data analysis. Baseline
ICAI was 7.9 for the test group (with a 95% Confidence Interval (CI) =
5.63 / 10.18), and 9.92 (95% CI = 7.72 / 12.12) for the control group. The
difference between the two groups, -2.01 (95% CI = -5.01 / 0.98) was
not statistically significant (p = 0.08). At 1 year follow-up, ICAI was 7
(95% CI = 4.17 / 9.82) for test group and 9.70 (95% CI = 6.57 / 12 82)
for control group. Neither this difference (-2.7 (95% CI = -6.63 / 1.23))
was statistically significant (p = 0.08). Patient’s opinion was high for
both groups but no statistically difference was found between two
groups. No important adverse event was found
Objectives: Tooth agenesis is one of the most common developmental dental anomalies. Successful and satisfying dental treatment is
always the goal for patients and dentists, meaning that a patient’s
needs are solved in a functional and esthetic way. Patients and
dentists have to find the best way to reach their common goal of
satisfaction. This case report shows the implant and restorative approach. In order to solve successfully this kind of challenges, an interdisciplinary treatment plan has to be worked out and executed
Methods: A 23 years old girl referred from Periodontics Department
in order to replace two congenitally missing lateral incisors to the
Prosthodontics department at Universidad Complutense de Madrid,
School of Dentistry. After completing orthodontic treatment, two dental implants (Straumann Bone Level Narrow CrossFit) were placed in
the lateral incisors spaces. During the healing time the patient used
and orthodontic retainer with the missing teeth added to it. Then,
soft tissue was managed using temporary abutments and crowns.
Customized impression posts were made to transfer the emergence
profile to the dental technician. Final restoration has been made
using individualized CAD-CAM zirconia abutments and crowns
(Straumann Cares Digital Solutions)
Results: Natural aesthetic and functional objectives and needs
were reached by an interdisciplinary approach
Conclusions: Good results only can be reached by an interdisciplinary team. The treatment plan has to be worked out by the orthodontist and preriodontist, but guided by the prosthetic team in order
to have the right space and implant position. Working together as
a team is mandatory to have the best result and a long lasting treatment for our patient

for overdentures based on implants are achievable; considering
the obtained satisfaction ratings, the examined prosthodontic treatment seems well tolerated by edentulous patients

Objectives: The single-tooth implant-supported restoration was a
longed-for option for treatment of missing teeth, especially in the
front region. Esthetic demands of practitioners for implant crown
in anterior region of the dental arches has prompted the development of ceramic abutments. Today, several kinds of implant
abutments are offered by implant manufacturers. When choosing
an abutment for an anterior single-unit case, several factors should
be considered: high vs low smile line; biotype of the gingiva; color
of the neighboring teeth; and finally, esthetic expectations of the patient. The purpose was to evaluate the results in the appearance of
marginal peri-implant soft tissues using zirconia abutments supported single-tooth restorations up to 3 years after insertion
Methods: Two young female patients, both with agenesis in anterior
region. After finishing the orthodontic treatment, received osseointegrated dental implants with internal connexion. The soft tissue can
be sculptured during the healing process by using a customized healing abutment. Astra Tech-Atlantis VAD™ (Virtual Abutment Design)
software, was use to designed the Y TZP (yttria-stabilized tetragonal
zirconia polycrystals) abutments, milled from a zirconia blank. Allceramic crowns were fabricated using the Procera® AllCeram System, solving the problem of transparency of the metal in the cervical margin area
Results: The peri-implant hard and soft tissues were largely healthy
and devoid of inflammation. In order to avoid difficulties removing
excess cement, screw-retained reconstructions may be preferred.
However, the screw access hole should be positioned palatal to the
incisal edge
Conclusions: Zirconia abutments for single-implant crowns seem to
demonstrate good short-term technical and biological results. The
clinical use of zirconia abutments is indicated when esthetics may
be of concern. In patient situations with thin peri-implant soft tissues
or where soft tissue migration occurs, zirconia abutments and allceramic crowns should be used in combination

Implant Supported Prosthesis
Objectives: Marginal fit between implant and prosthetic structures is an essential requirement in implant prostheses. Many authors highlighted the importance of obtaining a reduced microgap
between implant and prosthetic components. Inconsistencies can
be found at the margin as a result of unavoidable dimensional
changes that occur during definitive impression, master model fabrication, supporting structures fabrication and final esthetic and
functional coating. Digitalized technologies, defined as CAD/CAM,
are developing significantly. Their utilization has contributed to the
improve of the quality of precision and the predictability of implant
supported restoration. The purpose of this study is to evaluate the
marginal accuracy of full-arch screw retained restorations, fabricated by different technologies
Methods: 6 implant analogs were inserted on a titanium master
model. 20 bars of the same anatomical shape were fabricated on
this model. 5 bars were obtained with the conventional “lost wax
casting” tecnique casting six UCLA abutments with metal alloy. 15
bars were obtained through digitalized CAD-CAM technology. 10
structures were made of titanium and 5 of chromium/cobalt. The
20 bars obtained were measured using a CNC machine. After the
completion of these measurements, all the bars have been layered
with the appropriate ceramics (fifteen bars) and with the appropriate composite resin (5 titanium bars). When the prostheses were
considered completed, new measurements were completed in the
same manner described. All the data obtained has been analyzed
through a “virtual Sheffield’s test” calculating the absolute coordinates of the centers of the elements in the plan and their inclination
Results: The conventional bars presented significantly higher discrepancies from the model. These discrepancies have been substantially reduced after adjustments, performed in dental laboratory. The CAD-CAM bars presented reduced discrepancies from the
master model, with reduced range of variability compared with the
conventional bars. Titanium bars presented the smaller ranges of
variability among the tested groups. Significant differences were
present after layering with the esthetic materials, especially in the
conventional bars
Conclusions: CAD-CAM technologies represent an important alternative in fabrication of full-arch implant supported restorations. Its
utilization might reduce the gap between prosthesis and implants
and can guarantee a more predictable result
= 3.8; P = .08). No significant differences were found between the
upper and lower arch (P = .94), while a greater number of shifted
implants were found in post-extraction sites compared to healed sites (P<.05)
Conclusions: A shift of implant position can occur in immediate loading protocols during the first 4 months of healing and even more
frequently when implants are placed in post-extraction sites

Objectives: The aim of the present research is to evaluate if a shift in
dental implant position occurs during a four-month period, in case
of osseointegrated implants and in case of immediately loaded implants
Methods: Thirty-nine patients were selected and treated with fixed
full-arch dentures supported by 4-6 immediately loaded implants.
Twenty-nine patients were included in the test group. In this case
implant shift was evaluated comparing plaster impressions taken
at the moment of implant placement and then at 4 months post
implant insertion. In the control group (10 patients) the plaster impressions evaluated were taken at 4 months and then at 8 months
post implant insertion. Plaster casts were realized incorporating implants’ analogues. Special devices were screwed on the analogues.
Plaster casts were evaluated by 3D scanner laser and special software measured any implant shift that might be present between
the two casts for each patient. Only differences > 75 µm were taken
into consideration. Statistical analysis was performed by logistic regression and chi-square test
Results: There were no drop-outs and only one implant failed in the
test group (total: 195 implants evaluated). In the test group 34.5% of
the implants (50 out of 145 implants) showed a discrepancy of their
position > 75 µm. In the control group 28% of the implants (14 out
of 50 implants) showed a discrepancy > 75 µm. Considering only
displacements > 100µm the test group showed a four times greater
probability to present implant shifting than the control group (OR

Objectives: In some clinical situations, the length of either a prepared tooth or an implant abutment is shorter than ideal, and the
occlusal clearance to be restored by a porcelain crown is large. Incisal thickness of the coping and the veneering porcelain should be
considered to prevent mechanical failure of the crown. The purpose of this study was to investigate the influence of incisal veneering
porcelain thickness of a zirconia based all ceramic system (Etkon
Straumann) on failure resistance after cyclic loading
Methods: With a standardized technique, 48 anterior crowns with
2 different incisal thicknesses of porcelain veneer (2.0 and 4.0 mm)
and 2 different framework materials (Etkon Straumann Zirconia (Z),
and Ivoclar Leo (N), high noble metal) were fabricated to fit a implant abutment and divided into 4 groups (Z20, Z40, N20, N40) (n=12).
The crowns were cemented using resin cement (PANAVIA 21), thermal cycled and mechanically cycle loaded (49-N load) for 2,000,000
cycles. The specimens were evaluated for cracks and/or bulk fracture with an optical stereomicroscope (×10) and assigned a score of
success or failure. The specimens without bulk fracture after cyclic
loading were loaded along the long axis of the tooth, on the incisal
edge, in a universal testing machine at a crosshead speed of 1.5
mm/min until fracture. The fracture strength value (N) was recorded. The exact logistic regression and Fisher’s exact test was used to
study the effect of different alloys and porcelain incisal thicknesses
on the success and survival rates after cycle loading. The forces at
failure (fracture) of different groups was compared using the rank
transform-based nonparametric 2-way ANOVA (a=.05)
Results: A statistically significant difference (p<0.05)was detected in
the success rate after cyclic loading of all ceramic crowns vs me-

tal ceramic crowns (Z20 +Z40 vs N20+N40). The crown of group Z40
had a significantly higher success rate (p<0.05) compare to crown
in group N40
Conclusions: In conclusion, the all ceramic crowns showed significantly higher success rates after cyclic loading. Zirconia crowns
may allow up to approximately 4 mm of feldspathic porcelain on
the incisal area without increasing the failure rate

Objectives: The aim of the work was to verify the possibility to use
a non-conventional heating system, such as microwave sintering,
to consolidate commercial zirconia (Y-TZP) pre-sintered samples and
then comparing the results to the ones obtained with a traditional
electric furnace sintering
Methods: Two kinds of zirconia pre-sintered commercial samples,
METOXIT and BIOTECH, have been used. Microwave sintering: on
CEM-MAS 7000 multimode applicator (2.45 GHz, 950W nominal power) and on TE10n single mode applicator, connected to a 2.45GHz
TM030 microwave generator (Alter Srl, Italy, 0.5-3kW output power).
Conventional sintering on a traditional electric furnace
Results: METOXIT samples can be successfully sintered by using
single-mode microwave applicator. BIOTECH samples can be successfully sintered by using both multi-mode and single-mode applicator. No grain coarsening was observed after the treatment respect to pre-sintered samples
Conclusions: Microwave sintering allows to consolidate zirconia
commercial pre-sintered samples, with a decrease of sintering temperature and time; - The method produces specific advantages in
terms of energy, efficiency, saving costs, process simplicity and lower
environmental hazards; - Further experiments are still in progress
Objectives: Zirconia is a metastable material that is transformed
and stabilized in the tetragonal (t) polymorph phase from a monoclinc (m) phase during crown preparation. The re-transformation
from t to m phase can be induced by the application of external
tensions, increasing remarkably the fracture toughness of the material. This t-m phase transformation of zirconia crystals under load
is known as “transformation toughening”. The present study aimed
to evaluate if different marginal preparation of zirconia crowns (i.e.
deep-chamfer, slight-chamfer, feather-edge) produces a premature phase trasformation of zirconia immediately after the preparation and after chewing simulation using micro-Raman spectroscopy
Methods: 15 zirconia copings were prepared with a deep-chamfer, slight-chamfer or feather-edge finish line (n=5 per group), and
placed in a chewing simulator (CS-4.4, SD Mechatronik, Munich,
Germany) under a cyclic occlusal load of 50N for a total of 172,800
cycles to simulate one year of clinical service. 20 spectra for each
specimen were acquired with a modular spectrograph (Renishaw
InVia; Renishaw plc, Gloucestershire, UK, wavelenght 785 nm ) along
the cervical margin and 5 at the top of each coping, thus where
the load was distributed and applied before and after chewing respectively. When phase-transition of the zirconia occurs, the typical
bands of monoclinic zirconia (181 cm-1, 192 cm-1) appear near the
peaks attributed to tetragonal zirconia (148 cm-1, 264 cm-1). Acquired data were then analyzed with spectrographic analysis software
(Grams/AI 7.02; Thermo Galactic Industries Corp., Salem, NH, USA)
Results: The spectral region between 100 and 300cm-1, which contains all the vibrational bands necessary to provide reliable information on the extent of the t-m transformation, did not show the
typical monoclin bands at 181 cm-1and 192 cm-1. No changes were
detected in any of the tested group
Conclusions: After one year of simulated chewing activity, zirconia
crowns did not show any signs of t-m transformation, neither where
the load was applied, neither at the margins. Further studies are
needed to investigate if a longer chewing time can produce negative effects on zirconia

Objectives: The aim of the present study was to analyze the influence of the alloy, the cervical finish line design and the luting process
on the marginal fit of metal-ceramic restorations. The null hypothesis was that the alloy, the finish line design and cementation do not
have influence on the marginal fit of the restorations
Methods: One hundred and sixty specimens of brass were prepared to receive metal-ceramic crowns. The dies were divided
into two groups (n=80) according to the cervical finish line design:
chamfer or rounded shoulder. Every group was divided randomly
in four subgroups (n=20) according to alloy used: a) Pd-Au (Cerapall, Metalor), b) Ni-Cr (Viron 99, Bego) c) Ni-Cr-Ti (Tilite, Talladium)
and d) Ti (Biotan, Schütz Dental). All restorations were manufactured
using the traditional lost-wax casting technique according to the
manufacturer´s instructions. Glass-ionomer cement (Ketac Cem, 3M
ESPE) was used for cementation of the restorations. The marginal fit
was measured at four points before and after cementation: buccal,
lingual, mesial, and distal. The fit was assessed by measuring the
distance between the crown margin and preparation cavosurface angle, with an image analysis program (Optimas 6.1, Optimas).
Two-way analysis of variance (ANOVA) and Student paired t-test
were performed
Results: Accuracy of fit achieved for the groups analyzed was
within the range of clinical acceptance (<120µm), except for titanium group post cementation. The best marginal fit was observed
in the Pd-Au group with both finish lines precementation (rounded
shoulder 40 ± 15 µm and chamfer 27 ± 15 µm) and postcementation
(rounded shoulder 50 ± 14 µm and chamfer 38 ± 13 µm), showing
statistically significant differences (P=.05) with the other three alloys.
Chamfer finish line obtained lower marginal discrepancy values
than rounded shoulder pre and postcementation, but no significant
differences were demonstrated between the two finish line designs.
Luting process resulted in a significant increase of the marginal discrepancy in all groups (P=.001). Significant interaction between alloy and finish line design was demonstrated for values before luting
but not for values after luting
Conclusions: Based on the methodology used in this study, the fol-

Objectives: The aim of this investigation was to assess the influence
of several surface treatments on the shear bond strength of a selfadhesive resin cement containing MDP to densely sintered zirconia
ceramic, before and after thermal cycles
Methods: 60 densely sintered zirconia cylinders were divided into
three groups (n=20). Each of them received a different surface treatment: 1) control [No_T], with the zirconia surface unconditioned , 2)
low pressure air abrasion [Sand_S], (50µm, 1 bar) 3) standardized air
abrasion [Sand_H], (50µm, 2.8 bar). Three more surface-treated only
specimens were addressed to scanning electron microscope (SEM)
for qualitative observations. After specimen fabrication, subgroups
of ten bonded samples were stored in water either for 24 hours (T1)
or subjected to 5000 thermal cycles (T2); shear bond strengths (SBSs)
were determined with a universal testing machine at a crosshead
speed of 1 mm/min
Results: At T1, mean shear bond strengths (MPa) obtained for
[Sand_H] and [Sand_S] were 16.24 ± 2.95 and 16.01 ± 2.68, respectively; both low and hard pressure air abrasion positively affected
(p<0.05) the initial self-adhesive cement adhesion to zirconia with
respect to No_T (13.30 MPa). Artificial aging decreased the bond
strength in all test groups significantly, but no spontaneous debonding was observed in [No_T]: at T2, SBS values ranged from 7.77 ±
2.37 (No_T) to 8.89 ± 1.74 (Sand_S), with no statistically significant difference between groups (p=0.3849)
Conclusions: Hard and low pressure air abrasion produced comparable effects on cement-zirconia interface before and after
thermal cycles. After artificial aging, minimal differences in bond
strength values between sandblasted and control groups were not
of statistical significance

Objectives: The aim of this in vitro investigation was to analyze the
influence of the alloy and melting and casting technique on the
marginal fit of metal-ceramic restorations. The null hypothesis was
that the alloy and melting and casting technique do not have influence on the marginal fit of the restorations
Methods: One hundred and sixty standardized specimens of brass
were prepared to receive metal-ceramic crowns. The dies were divided randomly in four groups (n=40) according to the alloy: Pd-Au (Cerapall, Metalor), Ni-Cr (Viron 99, Bego), Ni-Cr-Ti (Tilite, Talladium), and Ti
(Biotan, Schütz Dental). Every group was divided into 3 subgroups according the melting and casting process: (A) induction and centrifuge
B) torch and centrifuge and C) electric arc and vacuum/pressure. All
restorations were manufactured using the traditional lost-wax casting
technique. The Pd-Au, Ni-Cr and Ni-Cr-Ti alloys were melted and casted using: A) Gas-oxygen torch and centrifugal casting machine (G3,
Mestra); B) Induction and centrifuge (MIE 200, Orodenta). The Titanium
alloy was melted and casting using Electric arc and vacuum/pressure (Ramantitan, Dentaurum). Glass-ionomer cement (Ketac Cem,
3M ESPE) was used for cementation of restorations. Image analysis
software connected to an Olympus microscope with a magnification
of 40x was used for measurements. Data obtained were statistically
analyzed using two-way analysis of variance (ANOVA) and Student´s
paired t-test. Level of significance (a) was set at .05 for all the tests
Results: The best marginal fit was observed in the Pd-Au group before and after cementation (33±16µm and 44±15µm respectively),
showing statistically significant differences with the other three alloys
groups (P=.05). Torch and centrifuge and induction and centrifuge
showed the lowest marginal discrepancies before cementation (43
± 20 µm and 49 ± 22 µm respectively) and after cementation (57 ±
22 µm and 59 ± 22 µm respectively) with no significant differences
between both groups but showing significant differences with the
electric arc and vacuum/pressure group (P=.05). The best marginal
discrepancies were observed for Au-Pd group and torch and centrifuge. No significant interaction between casting technique and
alloy was demonstrated
Conclusions: Accuracy of fit achieved for the groups analyzed was
within the range of clinical acceptance. The alloy and the melting
and casting technique had influence on the marginal fit of the restorations

Objectives: a 90-year-old healthy female patient was referred for
a fixed prosthetic rehabilitation of upper frontal teeth. After preliminary evaluation (photos, plaster casts, x-rays, periodontal probing,
scaling/rootplaning) a chronic periodontitis was diagnosed. A diagnostic wax up was planned for maxillary incisors replacement. Patient refused partial removable prosthesis. A computed tomography
was prescribed in order to make a treatment plan
Methods: maxillary incisors were extracted together with an enclosed cuspid. Implants were placed through a computer aided implantology technique, an immediate provisional was delivered and
after 4 months a zirconia CAD-CAM prosthesis was placed
Results: Definitive wax up, casts, framework and esthetic/functional teeth design were completely CAD procedures. The connection
between the framework and the implants was obtained using a
bonded titanium nitride system converter
Conclusions: Patients ask for esthetic, functional and immediate
fixed teeth. If they have good health, new technologies can help
dentists to obtain results even in the most difficult clinical cases because of age, treatment plan, anatomical conditions. This case report shows how patient desires can be satisfied by the dental team,
according to newest CAD-CAM procedures

Objectives: To assess the impact of prosthetic treatment on the oral
health-related quality of life of dental patients attending the University Clinic in Salamanca (Spain)
Methods: We performed a prospective cohort study at the University
Clinic in Salamanca in which a consecutive sample of dental patients was examined clinically at baseline and was later classified
according to the type of dental treatment received. Baseline oral
wellbeing was captured using the OHIP-14sp (Oral Health Impact
Profile 14-Spanish version). One month after treatment, the oral wellbeing was reassessed using the POST-OHIP questionnaire, in which
patients answered whether the treatment received had generated
a poorer, equal, or better effect on the 14 items of this retrospective instrument. The global score of the POST-OHIP test was obtained
by summing the response registered in the 14 items, in which the 3
response options were coded as better = “+1”; the same = “0” and
worse = “1”. Thus a global POST-OHIP score of >0 would imply a net
therapeutic benefit
Results: The sample comprised 255 dental patients (51.8% females)
with a mean age of 63.1 ± 12.7 years, distributed among the Prophylactic (15.7%), Restorative (11.8%), Perio-Surgery (7.5%), Prosthetic
(24.3%) and Comprehensive (40.8%) Treatment Cohorts. The baseline
scores of the OHIP-14 were not significantly different among cohorts,
but the Post-OHIP scores were significantly better among the PerioSurgery (3.5 ± 3.9), Prosthetic (3.7 ± 2.9) and Comprehensive Cohorts
(4.7 ± 3.1). On average, the patients followed up (n=227) perceived
global benefit after treatment (Post-OHIP mean score= 2.7 ± 4.0).
The risk ratio for perceiving a global benefit effect was more than
3 times higher for the patients receiving prosthesis (1.7; CI-95%= 1.32.2) than their counterparts (0.5; CI-95%: 0.3-0.7), and more than twofold higher for those receiving dental extractions (1.6; CI-95%: 1.1-2.2)
than their counterparts (0.8; CI -95%: 0.6-0.9), and those receiving
dental fillings (1.4; CI -95%: 1.1-1.8) than their counterparts (0.6; CI

Objectives: In the last decade, the use of laminate veneers have
become popular as a less invasive and conservative treatment modality for smile design enhancement. This study evaluate the clinical performance of pressed ceramic veneers placed at the Faculty
of Dentistry Timisoara, Department of Prosthodontics, after five years
of clinical service
Methods: 67 pressed porcelain veneers were placed in 21 patients
with age between 19 and 48 years, between March and July 2005.
The cases were carefully selected and occlusal guards were provided to patients with parafunctional habits. All veneers were fabricated with pressed ceramics (IPS Empress Esthetic). The veneers were
sandblasted, etched, silanated and were cemented using a dualcure cement. Clinical evaluations were performed at 6, 12, 24, 36, 48
and 60 months after insertion of the veneers. Modified Ryge criteria
were used to evaluate the veneers marginal adaptation, interfacial
staining, secondary caries, postoperative sensitivity and the satisfaction of the patients regarding the color of the veneers
Results: After 60 months of clinical service, 64 from 67 ceramic veneers were defined as successful, 2 restorations failed because of
chipping and one was debonded. The survival rate was estimated
to be 95,52% after 5 years
Conclusions: Within the limitation of this clinical study, pressed ceramic veneers showed good clinical results, after 5 years of clinical
service. They are considered an esthetic, conservative and durable
alternative for the restoration of the frontal teeth

Objectives: “Toothwear” is a generic term describing irreversible
tooth surface loss. One or more processes, not of bacterial origin,
may occur in toothwear. Dental erosion is a frequently underestimated pathology, recently recognized as a dental health problem
increasing in young individuals. For functional or aesthetic reasons,
toothwear may lead to an oral rehabilitation. In the past full mouth
rehabilitations, using fixed prosthodontics or removable overdentures, has been recommended in toothwear cases. Nowadays, as a
result of the improvements in composite restorative materials and
adhesive techniques, it is possible to rehabilitate eroded dentitions
in a less invasive way. A new 2-steps composite technique is described
Methods: We examined a 55-year-old man presenting extensive
erosive loss of tooth structure. Only after having visited and obtained a detailed history we determined that the cause of the problem
were attrition and erosion. In order to achieve the most predictable
aesthetic and functional outcomes, with the maximum of healthy tissue preservation, a 2-steps-composite-adhesive technique has been
used. During the first step a new posterior occlusion, with increased
vertical dimension, has been created using indirect composite onlays; at the same time direct anterior composites, were fabricated.
After 1 month, having tested the new vertical dimension as well as
the anterior guidance and aesthetic, the second step, consisting of
anterior composite veneers, was realized
Results: Rehabilitation has been functionally and aesthetically well
accepted by the patient. One year after treatment no signs of periodontal or temporomandibular joint dysfunctions were found and
composite restorations showed optimal adaptation and good clinical behavior
Conclusions: This experimental approach allows minimal tooth
preparation, maintenance of tooth vitality and optimal wear of the
antagonist dentition. This first positive outcome should be confirmed
by further clinical investiga
Implantology Research
Objectives: To compare periimplant bone resorption around machined and dual acid-etched (DAE) surfaced implants submitted to
an immediate loading protocol with a 36-months follow-up
Methods: Thirty-four patients were treated with maxillary full-arch
screw-retained prosthesis supported by 4-6 immediately loaded implants. The implants inserted (total: 163) were either implants with
DAE surface (n. 116) or implants with DAE surface and a machined
coronal portion (n. 47). Radiographic examinations were accomplished to assess interproximal bone levels at baseline and at the 12, 24
and 36-months follow-up appointments. Bone levels were analysed
using the repeated measures analysis of variance (ANOVA)
Results: All patients appeared at the scheduled recall visits. Ten implants (6.1%) failed while no prosthetic failures were detected. Significantly less bone loss was found using the DAE surfaced implants (P
< 0.001) at 24 and 36 months. At 24 months post implant placement
mean bone resorption was 1.41 mm next to the DAE implants and
1.58 mm next to the implants with machined coronal portion. At 36
months it was 1.54 mm and 1.65 mm respectively
Conclusions: Immediately loaded implants with dual acid-etched
coronal portion favored periimplant tissue integrity and showed less
interproximal bone resorption than implants with a machined coronal portion

Objectives: In the porcelain veneer technique a thin porcelain shell is
bonded to a minimally prepared tooth surface with a luting composite
in combination with an adhesive system. Two adhesive interfaces are
formed: resin to etched porcelain and resin to tooth structure. The aim
of this study was to investigate the ultra-structure and nanoleakage of
these two adhesive interfaces using different preparation designs and
luting times
Methods: Twenty maxillary anterior teeth were restored with porcelain
veneers, prepared with feldspathic ceramic, according to conventional procedures and divided into two groups as follows: 1) A) window
preparation (n=10) or B) butt-joint preparation (n=10) + impression +
storage in artificial saliva for 15 days at 37 C° + bonding with the adhesive system (Clearfil DC BOND, Kuraray Medical, Japan) + luting with
the cement (Clearfil Esthetic Cement EX, Kuraray Medical, Japan); 2)
A) window preparation (n=10) or B) butt-joint preparation (n=10) +
immediate application of the adhesive system (Clearfil DC BOND) +
impression + storage for 15 days in artificial saliva at 37 C° + luting
with the cement (Clearfil Esthetic Cement EX). Dye penetration (microleakage) at the veneer/cement/tooth interface was examined under
a stereomicroscope at a magnification of 40× by two different observers. Additional bonded interfaces were evaluated under scanning
electron microscope (SEM) for nanoleakage expression
Results: No significant differences of microleakage were found
between the groups. The different preparation designs and luting
times did not produce a significant nanoleakage expression. SEM
imaging of tooth/luting composite/porcelain interface showed
strong micromechanical interlocking
Conclusions: This study suggests that different preparation designs
and different luting times can all produce a stable interface between luting composite/porcelain and enamel. Further clinical research
is necessary to evaluate the long-term retention and sealing of porcelain veneers

Implant Supported Prosthesis
Objectives: Modern prosthetic rehabilitation of totally edentulous
patients is achieved by inserting implants into the residual alveolar
ridges, in order to provide support and anchorage for the future
restoration. There are several connection systems between implants
and overdenture, and bar rider system is one of them.
Dental technology and materials have evolved a lot over the past
decade. Today, the most popular materials for their oral biocompatibility and also aesthetic properties are considered to be zirconium
and gold. For this reason, we wanted to extend the use of these materials in prosthetic restorations on implants, too.
The aim of this paper work is to present a patient restored with a
mandibular overdenture retained by a continuous gold galvanoformed rider over a CAD-CAM zirconia milled bar supported by four
interforaminal implants that were early loaded
Methods: In this case report, the clinical and technical steps involved in fabrication of the implant prosthesis are described and prognosis of this type of restoration is discussed. The clinical and radiographic aspects at 2 years follow-up are also evaluated
Results: During this period of time no loss of retention was notice,
and patient was satisfied and felt comfortable with this type of prosthetic restoration
Conclusions: The accuracy of respecting clinico-technical steps
and mechanical principles applied to implants, combined with the
use of the most biocompatible materials and latest technology resulted in no clinical signs of periimplantitis and minimal periimplantar
bone loss on panoramic x-ray, at 2 years recall. Thus, the principle
of splinting implants for improving the primary stability, especially
needed when we are talking about an early loading protocol, was
implemented through the zirconium bar, and the principle of passive fit which is critical for the longevity of the whole assambly was
achived using galvanoforming technology

Objectives: Besides fullfilling the aesthetic standards, the ear epithesis should offer protection to the ear canal from harmful external
agents. The limitations in the construction of prosthetic ear depends on the type of material available, the amount of soft tissue not
perfectly adherent to the bone below, the prosthetic retention and
acceptance by the patient.
In large neoplastic defects, final results of a prosthetic reconstruction
can not be foreseen and are often limited
Methods: Total ear defects, secondary outcomes of neoplastic surgery, are fairly easy to repair, compared to partial defects in which
parts of the ear remain.
If possible,the tragus should be spared because it defines the line of
junction between the prosthesis and the skin.
After informing the patient about the nature of the defect and the
future prosthesis, before surgery, an impression of the patient’s ear
was made.
The silicone impression was taken with the patient in the supine position, considering the condylar movements, surrounding the area
of defect with boxing wax and closing the external auditory meatus
with gauze Vaseline.
Once cured, the impression material has been consolidated by the
interposition of Vaseline gauze, to the plaster impression, so as to
remove it.
The entire surface of the epithesis was modeled to mimic the skin as
much as possible.
Then the model was duplicated obtaining the ear wax, which was
then positioned and adjusted after the surgery.
With the help of mittens the wax prosthesis is transformed into silicon,
adapted to the patient and colorful
Results: As it is clearly portrayed in the pictures,the aesthetics was
so satisfactory to successfully mimic the lost ear. Thus a complete
image restoration could be achieved
Conclusions: Unsatisfactory aesthetic creates a state of anxiety, with
consequent difficulties in social interaction and the inclusion of the
patient
Objectives: Head and neck cancers represent about 10% of the total malignant tumours in males and 4% of total malignant tumours
in the female population, in Italy. There was an incidence of head
and neck cancers of 4,600/year in males and 1,300 in women, in
Italy in the early ‘90s. A glossectomy is performed to treat cancer of
the tongue. In most cases only part of the tongue is removed (partial
glossectomy). If the tissue loss left by the excision of the cancer is
small, it is commonly repaired by sewing up the tongue immediately or by using a small graft of skin. If the glossectomy is more extensive, care is taken to repair the tongue so as to maintain its mobility.
Complete removal of the tongue, called a total glossectomy, is rarely
performer, although it is currently accepted as a useful means of
managing selected cases of advanced tongue cancer
Methods: Approximately a month postoperatively, when the incisional wound healed well and granulations lined the floor of the
mouth, two dental implants were placed in the anterior region of
the mandible to create a retention site for the lower prosthesis wich
the artificial tongue will be anchored to. After four months, an alginate impression of the dental arches was taken and bases and wax
rims was made by the determination of horizontal and vertical relationships. After the assembling of the front teeth and the approval
of the patient, final resin prosthesis were constructed. The next step
was the reconstruction of the artificial tongue: first a wax tongue
was made respecting the anatomical spaces, then the final tongue
was made by Tecnovent silicon
Results: The patients who do survive often endure major functional,
cosmetic, and psychological burdens as a result of their difficulties
in speaking and eating. These aspects may be improved by the implant retained artificial tongue as portrayed in the current report
Conclusions: The normal process of swallowing consists of three
main phases: oral, pharyngeal and esophageal. The tongue normally plays the most important part in the oral phase, propelling
the masticated food material from the oral cavity to the oropharynx.
The volume occupied by the artificial tongue during chewing allows to push the bolus on the palate, thus facilitating the grinding of
food. An artificial tongue is immobile and cannot replace the pro-
pulsive movement of the tongue. The food is placed as far back as
possible near the molar teeth and after mastication it is decanted
into the pharynx by tilting the head backward

difference between the mean of the pixel values corresponding
to each PCR product treatment and control groups were evaluated with the Student’s t-test. A statistically significant difference was
found only at T1
Conclusions: Glycine powder air polishing has been shown to be
significantly more effective in reducing the probing depth and the
bleeding on probing index along with subgingival cultivable microflora (only at time 1). Therefore, this technique may be considered
as a viable alternative to the largely diffused hand instrumentation
Dental School ~ Università degli Studi di Torino - Turin
[1]
Objectives: The aim of this split-mouth clinical study was to compare
the efficacy of traditional plastic curettes to that of glycine powder
air-polishing in periodontal supportive therapy of dental implant
abutments.
A total of 15 patients with edentulous mandibles wearing overdentures supported by two implants were treated, between April and
July 2010. In each patient, the two implant abutments were randomly assigned either to hand-instrumentation by Teflon curettes
or to glycine based air-flow. The air-polishing device adopted was
used for 5 seconds onto each surface to remove the oral biofilm.
The hand-instrumentation was carried out with Teflon curettes for
the sub-gingival deposits and a scaler to remove the plaque from
the intra-oral part of the abutments
Methods: Patients were visited before the treatment (T0), 1 hr (T1),
1 week (T2) and 4 weeks (T3) after the treatment. Different parameters were considered: periodontal probing depth, bleeding on
probing and bacterial content within the gingival sulcus. Probing
maneuvers were performed by a plastic probe at T0, T2 and T3.
Regarding the microbiological samples, plaque was harvested (all
the time points) from the peri-implant sulcus with a sterile adsorbent
paper point. After the DNA extraction, the bacterial semiquantitative
analysis was performed with a broad range PCR in the conserved
16S rRNA bacteria genome region following an established protocol
Results: The results of the robust proportional odds regression model
an effect modification on bleeding with respect to time. Among the
patients treated with glycine, the odds of being in a higher category
of bleeding score at T0 is 3.55 the odds for those treated with curette
(95%CI: 0.98-12.9, p-value=0.054). Conversely, this OR reduces to 0.08
(p-value <0.001) and 0.1 (p-value= 0.04) as time increases. An effect
modification of the technique with respect to time is significant (pvalue= 0.01) also in the model for periodontal probing depth. The

Objectives: Our aims were: a) to obtain and fully characterize chemical/physical properties of titanium coated with PLL (PLLTi); b) to
perform in vitro studies on osteoblast cell line growth onto PLLTi disks,
to elucidate osteoblast cytotoxicity and cytodifferentiation, calcium
deposition into secreted matrix, pro-inflammatory cytokines production; c) to obtain in vivo evidence of osseointegration, through the
positioning of PLLTi implants in sheep mandibular bone
Methods: Sand blasted titanium disks. Titanium grade 4 was used in
this study to obtains disks (Ø 10 mm ) and oral implants (length 8 mm,
Ø 3.5 mm). Both disks and implants were sandblasted using MgC03
powder and then etched. Titanium PLL coating. Titanium disks/implants were incubated in PLL solutions (0.01M), at 37°C for 24 hours
(1 µg of PLL/mm of titanium surface). Material characterization. Contact angle, Atomic Force Microscopy and X-ray Photoelectron Spectroscopy were applied. In vitro tests. Mouse osteoblast-like cells were
seeded onto PLLTi disks, evaluating MTT, ALP activity, Alizarin Red S
assays, and pro-inflammatory interleuchin-6 production, at 1-7-1428 days. Cell morphology was ascertained using fluorescence microscopy. In vivo test. Ten Appenninica adult female sheeps were

euthanized at 12 and 24 weeks. Histology, microhardness (hardness
Vickers degree) and histomorphometric measurements were performed. Statistical analysis. Student’s t test (significance p<0.05)
Results: A homogeneous PLL coating was obtained, providing higher hydrophilicity and roughness to titanium disk surface: mean
contact angle of 45°; AFM images roughness of PLLTi with an average value of 291.708 nm/µm2; XPS highr N content.
No cellular toxicity, significantly enhanced osteodifferentiation (7
days) and calcium deposition (28 days), other than decreased interleuchin-6 production (at all experimental times), were found in
relation to osteoblasts onto PLLTi.
After 24 days, in vivo experiments revealed cortical bone microhardeness (90 ± 30 Vickers vs 40 ± 2 Vickers of the control site) and
bone-to-implant contact (80% vs 60% of the control site) significantly
improved in presence of PLL coating
Conclusions: Titanium PLL coating safely enhances osteoblast differentiation and implant osseointegration in animal, providing promising evidence for further in vivo studies with the final attempt to
optimize surface properties for dental and orthopedic implants

Objectives: From a review of literature is highlithed that the ability
of impression materials to retain copying and avoid its movements,
is essential for the prothesis precision on implant abutments restorations.
In the present study the Osstell Mentor device is used to evaluate the
skills of various impression materials to retain the transfert/copying.
This device analyses the resonance frequency (RFA) of a small
transducer linked to a dental implant. It assesses with a range of
ISQ (implant stability quotient)values, from 0 to 100, the quality of the
implant bone interface.
In the literature an ISQ value of 40 is considered as the minimum
value to allow an occlusal load of a succesfully osteointegrated implant.
In the present study this value has been considered as the cut off
between materials that produce a strong interface with the copying
or not
Methods: Neoss Implant Replica were used to simulate the transfert/
copying because they are able to be linked to the Osstell Mentor
transducer and because their geometry is very similar to the transfert/copying one. The speciments were produced with small boxes
because for their dimention and section has been possible to simulate an impression tray situation .
The measurements were taken after 10 minute,
after unscrewing and screwing the transducer on the head of analog/transfert and after 24 hours in order to simulate the clinical and
technician procedures
Results: The best material was the Ramitec Penta (single material
technique) and Ramitec Penta + Impregum Penta (double material
technique)
Conclusions: More than valuation of the analysis method proposed, considering the results obtained and literature consulted, which
states that an implant with a ISQ value higher than 40 is clinically
safe to substain a prothesic load, this work brings us to considering
the opportunity to evaluate Ramitec Penta for taking an impression
technique for single implant and more implants cases without splint
with acrylic resin or composite.
This mean a simplified impression technique and not influenced by
the dimentional deformations of resin based materials

Objectives: Thanks to the significant progress adhesive dentistry
has made, post placement might be avoided in light of a less-invasive tooth build-up approach. Objectives: To evaluate the influence of
the ferrule effect (1) and the fiber-post placement (2) on the fracture
resistance of endodontically treated teeth subjected to cyclic fatigue

Implantology Research
Objectives: The aim of this clinical retrospective study is to analyze
clinical and radiographic parameters of implants placed with ultrasonic implant site preparation (4 year follow-up). The data obtained
are compared with those reported in literature about conventional
implant site preparation with twist drills
Methods: One hundred eleven implants placed on 37 patients (on a
total of 1654 implants placed on 551 patients) were examined. The following parameters were analyzed: bone quality and quantity, implant
site and characteristics, loading protocols, prosthetic rehabilitation
type, peri-implant bone loss, plaque index and gingival index, implant
probing depth, peri-implant buccal soft-tissue recession, implant and
prosthetic survival rate
Results: Mean Plaque Index: 0,99 ; mean Gingival Index: 0,85 ;
mean Probing Depth: 1,9 mm; average bone resorption of 1,12 mm
during the first year and 0,13 mm/ year for successive years; mean
soft-tissue recession 0,17 mm/year; survival rate 99,09%; prosthetic
survival 100%
Conclusions: Preliminary data obtained from this study on 111 implants, in support of various types of prosthetic rehabilitation, are
comparable and in some cases better than the data available in the
scientific literature.Although this is a preliminary study, ultrasonic implant site preparation is able to guarantee superimposable survival
and prosthetic success rate to those reported in literature for traditional implant site preparation

Objectives: The first examination of a patient who requires complete functional and esthetic prosthetic rehabilitation, is one of the
most challenging tasks for the dentist. In the present study a clinical
complex case is described and reported, and an analysis is made of
the parameters of crucial importance in making the diagnosis and
in choosing a complete treatment plan; a further end-point was to
review the methods currently used for data collection
Methods: After obtaining the patients’ complete medical and dental history, we proceeded to collecting the data necessary for deciding upon and planning treatment. The clinical and radiographic
examinations were carried out, facial and intra oral photographs
taken, the study model analyzed and the virtual wax-up defined
Results: A virtual wax-up clearly showing the outcome of the procedure planned is of great value in communicating with the patient,
since it strengthens trust between the dentist and the patient (who
thus tends to be more ready to accept the treatment plan) The virtual wax-up is also a valuable tool for communicating to the dental
technician the data required for developing the diagnostic wax-up,
and for the subsequent indirect and direct mock-up
Conclusions: The virtual wax-up is a simple and economically viable means for showing the treatment plan to the patient, who is thus

ter storage at 37°C, specimens were restored according to four build-up approaches (n=10 per group): a. NF-NP (no ferrule, no post),
b. NF-P (no ferrule, fiber-post), c. F-NP (ferrule, no post), d. F-P (ferrule,
fiber post). RelyX Posts (3M-ESPE) were used in groups NF-P and F-P,
and were cemented with Panavia F 2.0 (Kuraray). A standardized
composite core was built, after which the specimens were restored
with an all-ceramic crown (IPS Empress CAD, Ivoclar-Vivadent) that
was cemented with Panavia F 2.0. Specimens were fatigued by exposure to 1,200,000 cycles using a chewing simulator (Willytech). All
specimens that survived fatigue loading were fractured using a universal loading device (Microtester, Instron). Data were statistically
analyzed using ANOVA
Results: Only one NF-NP specimen failed under fatigue. The ferrule
effect significantly enhanced the fracture resistance of the restored
teeth, regardless the use of a post (p=.003). F-NP obtained the highest
fracture resistance (758.52±121.89 N), which was not significantly different from F-P (647.58±132.95 N); NF-NP presented the lowest fracture resistance (361.52±151.69 N). For all groups, only ‘repairable’
failures were recorded. Interestingly, the 40% of F-P and F-NP failed
because of crown fractures
Conclusions: Avoiding extra-removal of sound tooth structure, rather than placing a fiber post, can protect endodontically treated
teeth against catastrophic failure. However, when any ferrule can
be preserved, a fiber-post may improve the retention and fatigue
resistance of the restoration

Preprosthetic Surgery and Implant Surgery
Objectives: Several of surgical techniques used for horizontal and
vertical ridge augmentation have been described by different authors. Especially in esthetic zone it is imperative to choose the appropriate technique for the patient in question
Methods: The first case showed an implant placed through simultaneous horizontal bone regeneration with non resorbable membrane and bovine bone mineral graft material.
In the second case a single implant was placed and the bone regeneration was conducted with split crest for ridge expansion. The
gap created by sagittal expansion underwent spontaneous ossification, following a mechanism similar to that occurring in fractures.
In the third case, the placement of a single implant was performed
with autogenous onlay bone graft harvested from mandibular
site. Particulated bone was associated as a filling material around/
between the bone block
Results: The augmentation of the bone and implant success were
obtained with all the three surgical techniques.
On the basis of available data and results, it appears difficult to
demonstrate that a particular surgical procedure offers better outcomes compared to another. Efficacious regeneration rate requirs
both a high level of technical skills and a thorough understanding
of major biological principles
Conclusions: Preoperative analysis of horizontal, vertical and sagittal defects, allows the oral surgeon to choose the appropriate surgical technique to ensure to the patient a functional and esthetic
prosthetic rehabilitation

welcome to our 30th International Congress!
Thanks to your always growing participation it has become one of the most important international events in
the prosthodontic field.
To held such an important meeting is a true responsibility. We must offer to each and every one of the members
of the prosthodontic community a valuable experience.
This has to be done also for every other member of the
dental community who is referring to prosthetic dentistry for coordination in an ever growing interdisciplinary
environment.
In the light of this reasons we have developed our 30th
International Congress as a joint between the future,
which is already among us in technologies and materials, and the past, which is of course still with us and our
patients in the fundamentals of biology, biomechanics
as well as in the principles of human relationships between clinicians and patients.
Our program is focused on a review of “fundamentals”
of prosthodontic treatment in its relation with the other
dental specialties: endodontics, restorative dentistry,
Saturday morning both the Martignoni Award and the
Polcan Award will be assigned.
Pleased to have you as our privileged guests after celebrating our 30th Congress we will also celebrate together Italy’s 150th anniversary on the last day of the
congress with a big surprise for everyone.
Welcome in Bologna!

periodontology, implantology. Each speaker will go
through precise questions dealing with clinical reality. A “counter speaker” will handle the discussion after
each lecture. The same approach will be held in the
dental technician section, a one day course on Friday
which we are sure will be of interest to all participants.
The technical session will also include the presentation
of the three best competitors to the Polcan Award.
On Saturday clinicians and technicians will meet in a
common session. Communication between clinicians
and technicians is a founding principle in AIOP history
and of course it is most important to achieve valuable
results.
From the pre-congress course to the collateral courses
for hygienists, assistants, a clinical course in dentures
as well as a special course in digital technologies: Digital Dentistry@AIOP is a new entry in AIOP ever growing
schedule, as digital has entered our practices and our
labs.
This year the Scientific session will see an even larger
participation thanks to high quality research coming
from Italian as well as international universities, all of
them will compete in the Mario Martignoni Award. On

Much is said about teamwork and it is now a
commonplace to say that it is absolutely essential in
implant dentistry (and in prosthodontics in general),
particularly in complex cases, to achieving a result
that best reconciles quality requirements, operating
times, prognosis and the financial and physical
resources both of the patient and of the team…
but is teamwork enough for the obtaining of
excellence?
This is no rhetorical question, teamwork in implant
dentistry presupposes rigorous organisation, shared
therapeutic aims and careful operational planning.
All these aspects will be shared with the audience
and a team of speakers who have pioneered
this approach from the birth of implant dentistry,
anticipating guided prosthodontic surgery using
implants not as a surgical “virtuosity” but as
restorative support for prosthodontic purposes, and
hence maintaining the centrality of the prosthetic
treatment plan from the planning stage to final
technical execution to ensure the very best for the
patient’s appearance and function. Strategies,
techniques and verification procedures will be
covered in a day that we are confident will add to
the cultural and operational assets of clinicians and
dental technicians, while offering food for thought
in the field of guided prosthodontic surgery.

The fundamentals of the prosthetic
abutment: endodontic, restorative
and periodontal aspects
The frequency with which the prosthetic abutment is
a vital and structurally intact element is increasingly
diminishing as the reliability and spread of implant
treatments spread. There are however many
situations where compromised teeth become a part of
prosthodontic treatment planning for various reasons
where reliability over time is essential. This congress
session will examine the fundamental endodontic,
restorative and periodontal requirements necessary to
ensure a good long term outcome.

The fundamentals of aesthetics in prosthodontics:
implant abutments and edentulous areas
Even in the absence of the periodontium, the treatment
of soft tissue is a crucial stage for the obtaining of a good
aesthetic outcome. The interaction between surgical
and prosthodontic skills is a determining factor for
marrying the tissue integration of the restoration with a
good prognosis. What can the surgeon do to create a
favourable environment for the prosthodontist? And what
can the prosthodontist do to ensure it is maintained.

Good communication between the prosthodontist, the laboratory and the patient:
a fundamental link in the chain for prosthodontics success
Communication is fundamentally important any time
that different individuals interact in furtherance of a
common aim. While the relationship between dentist and
dental technician is necessarily close, it happens all too
often that the patient tends to get left out, despite being
the person directly affected by the therapy.
What means can be employed to ensure the patient is
involved as the treatment plan unfolds? What means of
communication should be used as between dentist and
dental technician when formulating a therapeutic plan?
And which should be used during the execution stage?
This session will aim to answer these questions
particularly in relation to full arch rehabilitation and the
aesthetic sector.

The Italian Academy of Prosthetic Dentistry is associated with the
INTERNATIONAL FEDERATION ESTHETIC DENTISTRY (IFED), an organization born in 1994 on initiative of the American, European
and Japanese Academies of Esthetic Dentistry. Its purpose is to
contribute to the progress and development of worldwide esthetic and oral health and to enhance communication between
member Academies. Twenty-three dental societies from around
the world which focus on esthetic dentistry are now members of
this organization, and AIOP is the only Italian Academy to be recognized by IFED as representative of Esthetic Dentistry. Among
the other societies, you can find:
The International College of Prosthodontists (ICP) is an international organization founded by the American College of Prosthodontists and by a group of prosthodontists from different countries: Sweden (Bo Bergman), Australia (Lloyd Crawford), the U.K. (the
late Rowland Fereday, William Murphy, Harold Preiskel), Japan
(Makoto Matsumoto), the U.S.A. (Jack Preston), Switzerland (Peter
Scharer), and Canada (George Zarb). The ICP main purpose is to
promote the prosthetic activity and to spread and reinforce the
professional status of the prostodontist as a specialist. Last year
the AIOP was asked to join the ICP as Italian representative of the
specialty. The other Organization members are: the Academy of
Australian and New Zealand Prosthodontists, Academy of Prosthodontics of South Africa, American College of Prosthodontists,
Association of Prosthodontists of Canada, Chinese Prosthodontic
Society, Israeli Society of Prosthodontics e Korean Academy of

I principi endodontici fondamentali per il protesista
In molti casi, la protesi può essere realizzata su denti vitali. Spesso è tuttavia necessario un trattamento endodontico del dente
interessato. Il trattamento canalare rappresenta le fondamenta
su cui si andrà a costruire il restauro del dente.
Sebbene gli obiettivi dell’endodonzia siano rimasti immutati da
una cinquantina di anni, negli ultimi 15 anni c’è stata un’evoluzione delle tecniche e della tecnologia che ha reso i trattamenti
endodontici più affidabili, aumentandone i tassi di successo.
In quest’intervento si illustreranno le indicazioni e la prognosi
del trattamento e del ritrattamento endodontico. Si descriveranno inoltre gli aspetti fondamentali della clinica, nonché le tecniche che assicurano l’efficienza e la riproducibilità del trattamento endodontico, discutendo i diversi parametri che incidono
sull’esito a lungo termine.
Fundamental endodontics principles for the prosthodontist
In many cases, prosthodontist can be performed on vital teeth.
Nevertheless in some instances, an endodontic treatment of the
concerned tooth is required. The root canal treatment consitutes
then the foundations on which the restoration of the tooth will be
built.
Eventhough the objectives of endodontics have remained unchanged for the past half century, the evolution in techniques
and technology in the last 15 years have made endodontic treatments more reliable and have increased the success rate of the
treatments.
This lecture will review the indication and the prognosis of endodontic treatment and retreatment. It will describe the fundamental aspects of the clinics and the techniques that will allow the
endodontic treatment to be achieved efficiently and in a reproducible manner and will discuss the different parameters that
influence long-term success.

I principi ricostruttivi fondamentali per il protesista
I restauri protesici sono soggetti a fallimenti tecnici e biologici,
reversibili o irreversibili.
Una significativa quota di tali fallimenti è strettamente associata alle proprietà fisico-meccaniche e geometriche del pilastro
protesico. Risulta quindi di importante rilevanza clinica operare
adeguate strategie di trattamento, tecniche restaurative e selezione dei materiali nella ricostruzione del pilastro protesico.
Si configurano differenti tipologie di restauro preprotesico in relazione all’entità del deficit di sostanza dentale e conseguenti
capacità di contribuire alle forme di resistenza e ritenzione del
moncone protesico. Numerosi materiali e tecniche sono utilizzati
per la realizzazione dei differenti tipi di restauro pre-protesico.
I fattori che portano alla corretta scelta di tale restauro sono primariamente correlati al problema biomeccanico ovvero all’a-
nalisi della negativa distribuzione degli stress funzionali e parafunzionali al pilastro protesico.
Evidenza scientifica e clinica sottolineano come, ai fini del successo a lungo termine, realizzare un adeguato controllo delle
forze che incidono sul restauro protesico di denti strutturalmente compromessi, sia più rilevante della tecnica ricostruttiva. Ne
consegue l’importanza di individuare la presenza di un eventuale habitus bruxista del paziente, nonché realizzare progetti protesici e occlusione che mirino al massimo controllo delle
forze.
La sostanza dentale sana residua, dopo il controllo in quantità e
qualità delle forze incidenti, rappresenta il fattore più importante nella prognosi e nella selezione della tecnica di ricostruzione
del pilastro protesico. Anche le esigenze estetiche e la necessità di associare il restauro preprotesico a soluzioni protesiche
metal-free contribuiscono a tale decisione.
Fundamental restorative principles for the prosthodontist
Prosthetic restorations are subject both to technical and biological failure, which may or may not be reversible.
A significant portion of failures is strictly associated with the
physical, mechanical and geometric properties of the prosthetic
abutment. It is therefore clinically important to have in place a
suitable treatment and technical and restoration strategy, carefully selecting the materials to usedfor the reconstruction of the
prosthetic abutment.
There are different kinds of preprosthetic restoration according to
the extent of the deficiency of dental substance and the consequent ability to contribute to the resistance and the retention of
the prosthetic stump. Numerous materials and techniques are
employed in the making of different types of preprosthetic restoration.
The factors leading to correct restoration decisions primarily relate to the biomechanical problem, that is to say analysis of the
negative distribution of functional and parafunctional forces on
the prosthetic abutment.
Scientific and clinical evidence shows that for long term success,
correctly ascertaining the forces on the prosthetic restoration of
structurally compromised teeth is more important than the restoration technique itself. It is thus important to identify any habitus
bruxista of the patient as well as working out prosthetic and occlusion plans that maximise control of the forces.

Residual healthy dental substance, after checking on the quantity and quality of forces exerted, is the most important factor for
prognosis and for the selection of restoration method of the prosthetic stump. Also affecting the decision are aesthetic considerations and the need to associate preprosthetic restoration with
metal-free prosthetic responses.

I principi fondamentali per il protesista
In corso di terapia protesica del settore antero-superiore la decisione di posizionare per motivi estetici il margine del restauro
all’interno del solco implica, onde evitare lesioni tissutali ed ottenere una stabilità marginale nel tempo, i) una corretta valutazione dello stato di salute dei tessuti di supporto e del grado di
maturazione raggiunto dagli stessi quando sottoposti a terapia
chirurgica parodontale, ii) una attenta esecuzione sia durante
la fase di preparazione dentale sia nella gestione del profilo di
emergenza intra-tissutale del manufatto protesico.
Nel corso della presentazione saranno analizzate e discusse:
• Le basi anatomo-biologiche che determinano la risposta dei
tessuti marginali alle manovre terapeutiche. L’influenza del
biotipo genetico nel condizionare le modificazioni tissutali
post-chirurgiche. I criteri clinici per stabilire, nei casi trattati
chirurgicamente, l’appropriata tempistica di finalizzazione
protesica.
• Le precauzioni da osservare nella fase clinica della preparazione dentale.
• l’influenza del biotipo genetico nell’esecuzione e nella gestione del profilo di emergenza del manufatto protesico e le relative reazioni tissutali.
Fundamental periodontal principles for the prosthodontist
During prosthetic therapy for the upper frontal sector the decision
to position the restoration margin within the sulcus for aesthetic
reasons means it is necessary, to prevent tissue lesions and to
obtain margin stability over time, i) to correctly assess the state of
supporting tissue and the degree of maturation achieved by this
when subject to periodontal surgery, ii) to carry take particular
care in the execution of the therapy both during dental preparation and in the management of the emergence profile within the
tissue of the prosthesis itself.
During the presentation the following pints will be analysed and
discussed:
• the anatomical and biological factors that determine the response of marginal tissue to therapeutic manoeuvres The influence of the genetic biotype on post surgical changes. The
clinical criteria for establishing, in surgically treated cases,
the appropriate time frame for the completion of the prosthesis. work
• the precautions that need to be followed during the clinical
dental preparation stage.
• the influence of the genetic biotype on the performance and
the management of the emergence profile one of the prosthesis and the corresponding relationship with surrounding tissue.

I fondamentali dell’estetica in protesi:
pilastri implantari e zone eduntule
The fundamentals of aesthetics
in prosthodontics: implant abutments
and edentulous areas
Ricostruzione delle zone edentule
L’estrazione di un dente, e il conseguente processo di guarigione, comportano delle alterazioni morfologiche imprevedibili a
carico della zona edentula: tali alterazioni spesso provocano
problemi estetici di difficile soluzione. Esistono diversi metodi sia
per limitare la contrazione, qualora si possa intervenire al momento dell’estrazione o addirittura prima, che per correggere le
deformità della cresta quando queste siano ormai intervenute.
La relazione verterà sulla affidabilità e prevedibilità dei diversi
approcci secondo la letteratura scientifica attualmente disponibile e secondo l’esperienza dei relatori.
Restoration of edentulous areas
Tooth extraction and the ensuing healing process lead to unpredictable morphological changes in the edentulous area. These
changes often cause aesthetic problems that area not easily resolved. There are various methods in existence that can be employed both to limit contraction, where it is possible to intervene
at the time of the extraction or even before extraction, and to correct ridge deformity when this has already developed. The talk
will consider the reliability and the predictability of different approaches according to the literature currently available and on
the basis of the personal experience of the speakers.

Il piano di trattamento implanto-protesi
Nella regione mascellare anteriore, il risultato estetico è un fattore fondamentale nel determinare il successo complessivo della terapia implantare. Eppure, tale risultato è tutt’altro che scontato. Oltre all’osteointegrazione, uno dei fattori determinanti per
il successo del trattamento implantare è l’integrazione durevole
dei tessuti molli. Tuttavia, alcuni componenti implantari possono
interagire con il tessuto molle perimplantare che funge da sigillo biologico influenzando l’outcome. Nel trattamento ricostruttivo, l’interfaccia perimplantare è un tema di grande rilevanza
per la ricerca scientifica, poiché può risultare fondamentale nel
determinare la longevità dei restauri implantari e la loro sostenibilità estetica. Si sono identificati e segnalati vari fattori che
possono interagire con i tessuti perimplantari, influenzando rispettivamente la localizzazione verticale della cresta ossea e la
localizzazione dei tessuti molli perimplantari. Questi fattori sono
il morfotipo individuale, la qualità dei tessuti perimplantari, il
contesto del restauro e le proprietà del pilastro, tra cui anche la
natura della connessione.
Entrambi gli approcci, quello chirurgico e quello ricostruttivo,
hanno un’influenza sull’interfaccia perimplantare, e quindi anche sull’aspetto estetico delle ricostruzioni su impianti dentali.
Ciò sottolinea la necessità di comunicazione e linee guida per
entrambe le parti, per soddisfare le aspettative reciproche. La
presentazione identificherà i fattori di rischio e di successo, rispondendo all’interrogativo di quando, dove e come manipolare i tessuti molli perimplantari, con un approccio chirurgico o
ricostruttivo.
Aesthetic treatment planning in implant dentistry
In the maxillary anterior area, the esthetic outcome is a critical
determinant in the overall success of implant therapy and yet remains a challenge. Besides osseointegration, a long lasting soft
tissue integration is a key factor for implant success, but restorative components may interact with the peri-implant soft tissue that
serves as a biological seal and have an impact on the outcome.
This peri-implant restorative interface is a highly relevant subject
for scientific research, as it may be the key to longevity of implant
restorations and sustainability of implant esthetics. Different factors
have been identified and reported to interact with the peri-implant
tissues, respectively influence the vertical localization of the crestal
bone and the dimension and localization of the peri-implant soft
tissues. These are the individual morphotype, the peri- implant tissue quality, the restorative environment, and the property of the
abutment, including nature of the abutment connection.
Both, the surgical approach and the restorative concept have an
influence on the peri-implant restorative interface and thus the
esthetic appearance of implant-borne restorations. This underlines the need for communication and guidelines for both sides,
in order to meet the mutual expectations. The presentation will
identify risk- and success factors and address the question when,
where and how to manipulate the peri-implant soft tissue with a
surgical approach or either with a restorative approach.

Eccellenza nell’estetica dentale: nuove tendenze
e materiali in implantologia estetica
Nel corso della presentazione verranno illustrate le nozioni di
estetica di cui tenere conto nella gestione di impianti in zona
estetica, per raggiungere un’estetica e una stabilità ottimali a
lungo termine. Si insisterà sulla comprensione e sull’applicazione dei fattori biologici e tecnologici che influenzano l’esito del
trattamento. Restauri dentali con una grande attenzione per i
particolari, senza mai perdere di vista il quadro generale. L’estetica è rossa e bianca. L’odontotecnico ha un ruolo fondamentale nel raggiungimento di un risultato estetico ottimale, sia per
l’estetica rossa che per quella bianca. La vera sfida non sta nella stratificazione della ceramica, ma nell’assicurare l’armonia
dell’estetica rossa e di quella bianca.
Oggigiorno, le nostre azioni sono guidate dalle esigenze estetiche dei pazienti, che noi dobbiamo soddisfare. I materiali ceramici sono i materiali del futuro. Si intendono tutte le ceramiche,
con la zirconia al posto del metallo. Questo materiale apre molte
porte per l’implantologia estetica.
In questo contesto, i restauri senza metallo stanno diventando
sempre più importanti. Le moderne tecnologie CAD/CAM sono
finalmente in grado di assicurare una qualità costante e la precisione dei restauri privi di metallo.
L’odontotecnico non è più principalmente un tecnico, ma è diventato parte integrante dell’odontoiatria e delle professioni sanitarie. Per una gestione ottimale dei casi è fondamentale un
approccio interdisciplinare, come si vedrà attraverso una carrellata di casi che vanno dai casi singoli alle ricostruzioni complesse di più elementi.

optimum long term aesthetics and stability. The emphasis will be
on an understanding and application of the biological factors
and technology that influence our treatment outcomes. Dental
restorations with loving attention to detail, while never losing
sight of the overall picture. Aesthetics is red and white. Dental
technology has a considerable share in achieving an excellent
aesthetic result - red aesthetics and white as well. The true challenge does not lie in ceramic layering, but in bringing red and
white aesthetics into harmony.
Today, the aesthetic demands of the patients guide our actions
- and we have to satisfy these demands. Ceramic materials are
the materials of the future-and that means all ceramics, with
zirconia replacing metal. This material opens many doors for
aesthetic implantology.
In this context, metal-free restorations are becoming increasingly
important. And modern CAD/CAM technologies are finally able to
ensure consistent quality and precision of metal-free restorations.
Dental technology is no longer primarily a technical craft, but
has become an integral part of dentistry, a member of the healing professions. An interdisciplinary approach is the key to optimal case management and this will be demonstrated by cases
ranging single tooth to complex multiple tooth restoration.

PROTOCOLLO OPERATIVO PER IL LABORATORIO
ODONTOTECNICO: DALLA “FILOSOFIA” ALLA PRATICA
Operating protocol for the dental
laboratory: from “philosophy” to practice
Oggi prendere la decisione di costruire una attività odontotecnica significa sviluppare un modello di un’idea geniale, unica, un
qualcosa che non esiste nel mercato odontotecnico; sembra un
semplice laboratorio senza vocazione, trova difficoltà di interessare. Questa idea si basa su una filosofia concettuale.
Questo concetto non funziona se i collaboratori non condividono
questa idea. Però anche un odontotecnico che cerca collaborazione con altri è costretto a sviluppare una idea personale.
Questa idea deve svilupparsi nel periodo di insegnamento e
questo sviluppo è l’obiettivo dell’insegnamento
In occasione di questa relazione ci chiediamo: dove si cela il
segreto del successo di un odontotecnico?
Quali sono i criteri di un lavoro di successo?
In tutti i nuovi scenari emergenti è fondamentale valutare il proprio prodotto in modo critico, nella consapevolezza del fatto che
nessuna tecnologia e nessuna produzione industriale è possibile senza l’intervento dell’odontotecnico.
Si domanda, quale tipo di odontotecnico o quale idea di lavoro
è ricercato?
La domanda centrale è: come crescere con il proprio lavoro?
Come odontotecnici siamo talvolta divisi tra fascino e disagio?
La richiesta di materiali sembra essere sempre più al centro
dell’interesse. L’odontotecnico dovrebbe usare materiali facili
da lavorare e dovrebbe lavorare con processi tecnici semplici
e con maggiore concentrazione sul proprio prodotto, dovrebbe
quindi poter ottenere risultati gradevoli con mezzi semplici.
Quanto conta il materiale richiesto?
Quando e dove inizia la collaborazione con l’Odontoiatra?
Come procedereste?
Come cerchereste il vostro posto nella professione?
Che innovazioni scelgo?
Si vuole suscitare il coraggio e motivare gli odontotecnici, a prescindere dalla scelta dei materiali e dei sistemi con i quali si
struttura il proprio lavoro.
Questo richiede un procedimento ben definito nell’ambito della
collaborazione, nonché conoscenze profonde della tecnica effettiva e dei relativi effetti tecnici sulla realizzazione delle sottostrutture. Queste conoscenze hanno un influsso diretto sull’effettiva pianificazione dei casi di entrambi i partner professionali.
Con questo intervento desidero deviare l’attenzione dell’ascoltatore dal mito dei segreti dell’arte e contemporaneamente illustrare con precisione quali dati devono essere comunicati per
la pianificazione dei casi, per garantire il massimo in termini di
successo del medico nel trattamento.
La collaborazione strutturata in maniera conseguente assumerà quindi un posto centrale in questo intervento.
Today deciding to build up a prosthodontics business requires
the development of a unique idea and model, to provide something that does not already exist in the market – it seems that
a simple laboratory with no real vocation is unlikely to interest
anyone.
The idea has to be based on a conceptual philosophy. This will
not work if those working with you do not embrace the Ide a–
However, even a dental technician that seeks to work with others
must also develop his or her own personal idea.
This Idea must be developed during the training period, and its
development is the objective of the teaching
During the talk we will ask ourselves:
Wherein lies the secret of success for a dental technician?
What are the criteria for a job well done?
In all of the newly emerging scenarios it is fundamentally important to critically appraise your own product, fully aware of the
fact that no technology and no industrial production is possible

without the intervention of the dental technician himself. It must
be asked what type of prosthodontics is involved and what working idea is being sought.
The question is central to the growth of the business.
As dental technicians we are sometimes torn between appeal
and discomfort. The demand for materials seems to be increasingly the centre of interest. The prosthodontist must use materials
that are easily worked and must employed simple techniques
with greater concentration on his own product, and should therefore be able to achieve pleasing results using simple means.
How much does the material requested cost? When and where
does the cooperation with dentist start.
How should you proceed? How you find your place in the profession? Which innovative process should be selected?
The dental technician should be encouraged and motivated, irrespective of the question of choice of materials and systems by
which his work is structured.
This requires a well defined procedure in the area of cooperation, as well as expert knowledge of the actual method and the
technical effects on the building of the sub-structure. These areas
knowledge directly affect the planning of cases for both of the
professional partners.
The aim of the talk is get away from the myth of arcane secrets
of the trade while illustrating exactly what information needs to
be communicated for good planning in any given case, ensuring the best possible outcome for the dentist’s treatment of the
patient.
The idea of cooperation structured in relation to such needs will
form the central pillar of this talk.

LA CORRETTA COMUNICAZIONE FRA STUDIO,
LABORATORIO E PAZIENTE: ANELLO FONDAMENTALE
NELLA CATENA PER IL SUCCESSO PROTESICO
Good communication between the
prosthodontist, the laboratory and the
patient: a fundamental link in the chain for
prosthodontics success
La comunicazione nella riabilitazione della zona estetica
L’obiettivo è disegnare un sorriso che soddisfi le esigenze funzionali, estetiche ed emozionali dei pazienti.
Le tecniche e i materiali, per quanto moderni, possono risultare
inutili se il risultato finale non soddisfa le aspettative estetiche
del paziente.
Si insisterà sull’utilizzo di strumenti digitali per migliorare e semplificare il lavoro del team e la comunicazione con il paziente.
Il protocollo proposto migliorerà la diagnosi, la comunicazione
e la predicibilità delle riabilitazioni estetiche.
Obiettivi di apprendimento:
1. L’importanza dell’analisi del viso e il suo ruolo fondamentale
per un disegno del sorriso ottimale.
2. Strumenti di comunicazione interdisciplinare.
3. Un protocollo semplice ed efficace per le fotografie.
4. Il ruolo dei mock-up e delle cerature per migliorare il processo di disegno del sorriso.
5. Migliorare la comunicazione tra l’odontoiatra e il paziente.
6. Strumenti digitali per migliorare la comunicazione tra l’odontoiatra e il ceramista.
Communication in the field of aesthetic rehabilitation
The goal is to design a smile that fits the patients functional, esthetic and emotional needs.
Modern techniques and materials can be useless if the final outcome doesn’t achieve the patient esthetic expectations.
Emphasis will be given to the utilization of digital tools to enhance and facilitate the team work and communication with the
patient.
The protocol proposed will improve the diagnosis, communication and predictability of esthetic rehabilitations.

La comunicazione nella riabilitazione estese
La relazione verterà essenzialmente sulla comunicazione fra
dentista, odontotecnico e paziente nella fase di pianificazione
delle riabilitazioni complesse.
La pianificazione è troppo spesso sottovalutata a vantaggio della gestione: in realtà una corretta gestione trova il suo presupposto solo in un’ accurata fase di pianificazione.
La ceratura rappresenta la concretizzazione del progetto clinico-tecnico elaborato durante il piano di trattamento preliminare, ed è anche lo strumento fondamentale di comunicazione fra
il dentista ed il paziente durante la rivalutazione del caso e la
presentazione del progetto.
Le fasi di esecuzione tecnica della ceratura rispecchiano il processo logico di pianificazione clinica, riassumibile in tre punti:
1)utilizzo dei rapporti oro facciali per posizionare i denti ed
orientare i piani occlusali
2) creazione di guida anteriore e contatti uniformemente distribuiti posteriori
3) sviluppo di una forma protesica che assicuri agevole mantenimento igienico.
Verranno presentati casi di gravi disarmonie scheletriche, su
denti ed impianti, per mostrare come, con la ceratura, possiamo verificare, prima dell’inizio della terapia attiva, la possibilità di soddisfare contemporaneamente tali obiettivi, sulla base
dell’assunto che quanto non è raggiungibile con la ceratura,
non potrà essere raggiunto neppure clinicamente.
Communication in full arch rehabilitation
The talk will essentially concentrate on communicationsbetween the dentist, the dental technician and the patient during
complex rehabilitations.
Proper planning is all too often undervalued through special emphasis on management, while the fact is that the basis of proper management rests on the foundations of a careful planning
stage.
Waxing is the realisation of the clinical and technical plan
worked out during the preliminary treatment plan, and is also
the fundamental instrument for communication between the
dentist and the patient during reassessment of the case and the
presentation of the plan.
The technical execution of the waxing reflects the clinical planning process that can be summarised in three major points:

Learning Objectives:
1. The importance of facial analysis, the key for ideal smile design.
2. Interdisciplinary communication tools.
3. Easy and effective digital photography protocol.
4. The role of mock-ups and wax-ups to improve the Smile Design process.
5. Improving the dentist/patient communication.
6. Digital tools to improve the dentist/ceramist communication.

1) the use of orofacial ratios for the positioning of the teeth and
the guiding of the occlusion planes
2) the creation of a frontal guide and uniformly distributed posterior contacts
3)the development of a prosthetic form that ensures easy hygiene maintenance.
Cases will be presented that illustrate serious disharmonies skeletally, dentally and in relation to implants while showing how
waxing can be used to assess, before the start of active treatment,
the possibilities of satisfying the all objectives simultaneously, on
the assumption that what something cannot be achieved in the
waxing stage will also be unobtainable clinically.

Basic CAD-CAM CONCEPTS: CLINICAL AND
TECHNICAL ASPECTS
Impronta ottica: due anni di esperienza nella realtà clinica
Il trasferimento delle informazioni relative alla bocca del paziente, necessarie al laboratorio odontotecnico per la progettazione e la realizzazione del dispositivo protesico, è sempre stato
oggetto di grande interesse. L’avvento dell’impronta ottica fornisce nuove prospettive nella gestione virtuale della realizzazione
protesica, ponendo d’altro canto quesiti riguardanti l’intero sviluppo del flusso di lavoro. La relazione sarà basata sugli aspetti
gestionali (comunicazione con il laboratorio, costi, organizzazione e formazione del personale di studio…), e operativi (integrazioni delle differenti fasi di realizzazione del dispositivo, utilizzo
integrato di altre informazioni digitali, la precisione del dispositivo… ) che oggi ne condizionano l’utilizzo alla luce di due anni
di esperienza nella pratica clinica.
Optical impressions: two years of clinical experience
The transfer of information regarding the mouth of the patient,
clearly essential for the prosthodontics laboratory and for the design and construction of the prosthetic device, has always been
a matter of special interest. The advent of the optical impression
provides new perspectives for virtual management of the realisation of the prosthesis, while raising questions about the whole way
in which the work develops. The paper will be based on management aspects (communication with the laboratory, costs, the
organisation and training of personnel and so on), and on operational matters (integrating different stages in the construction of
the device, the integrated use of other digital information and the
specifications of the device … ) which determine practice today,
with input gathered from two years of clinical practice.

Tecnologia CAD-CAM: come, quando e perché
La tecnologia CAD-CAM entra prepotentemente sempre più nel
mondo della protesi dentale, sia nella realizzazione che in diagnosi.
Ma le macchine possono sostituire l’operatore?
Esiste corrispondenza, nei protocolli lavorativi già noti agli operatori, tra virtuale e “manuale”?
Si può integrare a 360° una tecnologia CAD-CAM nella routine
lavorativa e nel rapporto tra laboratorio e studio?
Questi sono solo alcuni quesiti che ci dovremmo porre e a cui
dare una risposta prima di affrontare l’argomento. Dopo di che
avremmo sicuramente le idee più chiare su quali sistematiche
CAD-CAM porre la nostra attenzione.
CAD-CAM technology: how, when and why
CAD-CAM technology is ever more imposingly entering the world
of dental prostheses, both as regards construction work and in
diagnostics.
But can the machine take the place of the professional?
Is there correspondence between working protocols already
known to the operators with regard to both to virtual and to “manual” skills?
Can CAD-CAM technology in the round be fully integrated into
the working routine and into the relationship between the laboratory and the dental surgery?
These are just some of the questions that need to be raised and
answered before the argument can be addressed. This will clear
the air and enable us to concentrate on which CAD-CAM systems
should be considered.

La riabilitazione di un paziente edentulo, è, senza dubbio, un’esperienza estremamente impegnativa per un team-work protesico, indipendentemente dalla multidisciplinarietà del piano di
trattamento, e, spesso, può rivelarsi tra le più complesse della
nostra branca specialistica.
Quando le scelte terapeutiche si orientano verso una soluzione
rimovibile, ad esclusivo appoggio osteo-mucoso, le difficoltà
aumentano in termini esponenziali, in virtù, soprattutto dei seguenti fattori:
- la qualità delle strutture anatomiche residue, che rappresentano le coordinate del sistema stomatognatico, in cui inseriremo i nostri manufatti protesici;
- la psiche dell’essere umano che, nella fattispecie, è il paziente che si accinge a sottoporsi al trattamento di riabilitazione;
- infine l’esigenza di dover realizzare un manufatto a perfetta
imitazione del modello naturale, che risulti essere un elemento integrante essenziale.

Pertanto, quali strategie vanno adottate per una predicibilità
di successo? Gli autori risponderanno a questo quesito, proponendo, la propria sistematica di lavoro che ha come obiettivo
primario preservare l’omeostasi del sistema stomatognatico,
che, nel contesto dell’edentulia totale, si identifica nel ripristino
a lungo termine della funzione masticatoria con la conservazione dell’altezza delle creste residue e nel rispetto dei parametri estetici e fonetici che hanno un importante ruolo nella
vita di relazione. Trattasi, nella fattispecie, di una metodica di
lavoro, che si ispira, sì, ai principi della scuola americana con
la quale si identificano ed, in particolare, agli insegnamenti del Maestro Prof. Gino Passamonti, a cui va la loro infinita
riconoscenza, ma, contestualmente, prevede alcuni aspetti

The rehabilitation of the edentulous patient is without doubt the
most challenging of situations for the prosthodontic team, irrespective of the interdisciplinary nature of the treatment plan,
while these are often among the most complex areas in our
branch of medicine.
When the treatment plan suggests a removable solution with
only osteo-mucosal rest, the difficulties increase exponentially
due particularly to the following factors:
- the quality of the remaining anatomical structures which are
the coodinates of the stomatognathic system into which the
prosthetic devices will be inserted,
- the emotional situation of the human being facing rehabilitation therapy;
- the need to construct a prosthesis that is a perfect immitation
of the natural model, for which it will be an essential integrating element.
What, then, are the strategies to be employed that will ensure a
successful outcome?
The authors will addres the question by proposeing their own
working system which has as its primary aim that of preserving
the homeostasis of the stomatognathic system which, in the case
of complete edentulia amounts to long term masticatory function with the conservation of the remaining ridge heith and in
accordance with the aesthetic and speech needs that are so important to interpersonal relations.
In this case it is a working method baded on the principles of
the American school with which the team identifies and in particular the teachings of Professor Gino Passamonti to whose great
thanks are due. This simultaneously involves certain aspects of
performance and materials that are extremely innovative and
hence of certain interest to all. There will therefore be a very detailed presentation of several cases of complete edentulia, with
educational importance, that will hopefully encourage the audience to wish to study further the area of full arch prostheses.

IL MANTENIMENTO DELLA PROTESI: QUELLO CHE
L’IGIENISTA DEVE SAPERE E FARE
PROSTHESIS MAINTENANCE: WHAT THE HYGIENIST
NEEDS TO KNOW AND DO
Il corso odierno ha come argomento la longevità dei diversi
trattamenti protesici. In particolare sarà discusso il ruolo dell’igienista sia nel mantenimento delle riabilitazioni protesiche, sia
nell’intercettazione delle loro complicazioni.
L’igienista deve conoscere i risultati degli studi clinici sulla durata della protesi fissa, rimovibile ed implantare, i diversi fattori
che influenzano la prognosi di una riabilitazione protesica, le
principali cause di fallimento, le diverse complicazioni e la loro
frequenza.
L’igienista deve essere in grado di rispondere correttamente alle
domande dei pazienti sulla durata del lavoro protesico, educarli alla necessità del mantenimento periodico, valutare l’integrità
delle protesi, ed intercettare l’eventuale presenza di recidive cariose o parodontali.
Sarà inoltre descritto come l’igienista può aiutare il dentista nella determinazione della prognosi della riabilitazione protesica,
e saranno confrontati i protocolli di mantenimento personalizzati sulle necessità dei singoli pazienti.
Today’s is a refresher course whose subject is the length of life of different prosthetic therapies. The discussion will in particular consider the
role of the dental hygienist in the maintenance of prosthetic rehabilitation and in helping to prevent complications arising.
The hygienist must be aware of the result s of clinical studies on the
life of fixed, removable and implant prostheses, the various factors that
influence the prognosis for the prosthetic rehabilitation, the principal
causes of failure and the complications that can ensue and their frequency.
The hygienist must be able to answer the patient’s questions about the
length of life of the prosthetic work, to educate the patient about the
need for periodic maintenance, to assess the integrity of the prosthesis
and where necessary to intercept any presence of carious or periodontal recidivism.
There will also be an explanation of how the hygienist can help the den-

IL RUOLO DELL’ASSISTENTE NELLO STUDIO
ODONTOIATRICO. IL LAVORO IN TEAM
THE ROLE OF THE DENTAL ASSISTANT IN THE DENTAL
OFFICE. TEAM WORK.
La complessa organizzazione di uno studio dentistico efficiente
prevede la suddivisione di competenze specifiche tra i vari componenti l’equipe odontoiatrica.
L’Odontoiatra deve dedicarsi alla cura del paziente delegando
le tematiche burocratiche e organizzative a personale preparato e competente: le assistenti di studio e la segreteria.
Dall’accoglienza dei pazienti al loro congedo, tutto deve essere curato nei minimi particolari. L’assistenza e la preparazione
dell’atto odontoiatrico, ovvero al sterilizzazione, la pulizia delle
sale operative, la gestione del magazzino e il rapporto con il laboratorio devono essere organizzate con rigore affinchè il flusso
di lavoro all’interno dello studio scorra senza problemi o ritardi.
L’Odontoiatra ed il suo Team devono lavorare in sinergia partecipando attivamente sia all’atto medico che all’organizzazione
di tutto lo studio per proiettarlo nel suo insieme ad ottenere il
massimo risultato nell’interesse del paziente.
The complicated organisation of an efficient dental surgey subdivides work into specific areas of competence as between the
various members of the dental team.
The dentist must dedicate his or her efforts to the treatment of
the patient and delegate the bureaucratic and organisational
aspects to well trained and competent staff, i.e. to dental assistants and secretaries.
Every detail from the time the patient is welcomed to the surgery
to the time he leaves must be attended to with care. The assistance and the preparation work for the dental work itself, include
the sterilisation and cleaning of operating rooms, the management of stock and dealings with the laboratory must all be strictly
organised in such a way that the work within the dental surgery
flows freely and without problems or delays.
The dentist and the team must work together in synergy and actively participate both in the medical side and in the organisation of the whole of the dental surgery system as a whole to assure
the best possible results in the interest of the patient.
