13. Avaliação da resistência de união de um cimento resinoso a um filme vitrocerâmico depositado em superfície de Y-TZP / Evaluation of bond strength of a resin cement to ceramic film deposited on a surface Y-TZP
The use of Y-TZP for dental ceramics strengthening has expanded significantly its mechanical properties, allowing its use in various clinical situations such as intraradicular, crowns, fixed partial dentures and implants. With the development of these new ceramic systems the use of traditional methods for surface treatment have been observed to be ineffectiv

14. Desajuste marginal e influencia na pre-carga de parafusos e nas tensões induzidas as fixações de pilares metaloplasticos sobre-fundidos / Marginal misfit and influence in the pre-load and the stress-induced setting of the metaloplastic abutments
Castable UCLA abutments are of wide applicability in dental implants, because they allow the manipulation in the laboratory at low cost and individualization of abutments for each patient. However, they show the worse results of marginal adaptation then the fabricated, although these aggregate costs significantly higher. UCLA premachined abutments for castin

15. Effect of pontic framework design on the fracture resistance of implant-supported all-ceramic fixed partial dentures
OBJECTIVE: The purpose of this study was to compare the fracture resistance of implant-supported all-ceramic fixed partial dentures, which have three different pontic designs. MATERIAL AND METHODS: Two implants were placed in a metal model simulating mandibular left second premolar and mandibular left second molar. Thirty standardized 3-unit all-ceramic fixe

16. Ceramic restoration repair: report of two cases
The esthetic and functional rehabilitation of patients with multiple missing teeth can be performed with several techniques and materials. Ceramic restorations provide reliable masticatory function and good esthetics. However, fracture can occur in some cases due to their brittle behavior. In some cases, the replacement of an extensive prosthesis is a proble

17. Influência do contato interproximal em próteses fixas implanto-suportadas na mandíbula edentada posterior análise fotoelástica
O uso de próteses parciais fixas em reabilitações de áreas edentadas posteriores inferiores com implantes é um fato bem documentado, apesar de haver controvérsias sobre a esplintagem ou não de coroas sobre implantes nessas condições. Logo, o objetivo deste estudo foi analisar o efeito da separação das coroas de uma prótese parcial fixa sobre impl

18. Influência do formato do pilar na capacidade retentiva de copings metálicos cimentados sobre implantes
This study evaluated the influence of the abutment design on the retention of cementretained, implant-supported metallic copings. Two abutments of the same system, with the same height, indications and total occlusal convergence, but of different designs were evaluated. Ten RN SynOcta abutments and ten RN solid titanium abutments both manufactured by Strauma

19. Accuracy of stone casts obtained by different impression materials
Several impression materials are available in the Brazilian marketplace to be used in oral rehabilitation. The aim of this study was to compare the accuracy of different impression materials used for fixed partial dentures following the manufacturers' instructions. A master model representing a partially edentulous mandibular right hemi-arch segment whose te

20. Reasons for determining the election or rejection of the types of prosthetic treatment in partially edentulous / Motivos determinantes da eleição ou recusa de tipos de tratamentos protéticos em desdentados parciais
The aim of the study was to explore preferences and reasons for choosing or refusing prosthetic treatments in partially edentulous patients. Clinical and oral-related quality of life measures were collected from 165 patients undergoing dental treatment in undergraduate clinical activities in the School of Dentistry of the University Federal of Goiás. Reason

21. Implant supported prosthesis : influence of abutment and porcelain firing cycles on misfit and stress around implants / Proteses fixas implanto-retidas : influencia do pilar intermediario e dos ciclos de cocção da ceramica nos desajustes e nas tensões induzidas as fixações
It is speculated that porcelain firing cycles cause an increase on marginal misfit. This effect is imagined to origin an increase on strains around implants, when screwing the metallic frameworks, and it is supposed to be decreased by the use of an abutment between the framework and the implant. Thus, the aim of this study was to evaluate the influence of th

22. Influência da distância inter-pilar e tipos de fibras de reforço na resistência à fratura de próteses adesivas indiretas
This study evaluated the fracture strength of fiber-reinforced composite inlay fixed partial dentures according to the pontic distance and the type of fiberreinforcement. One hundred and twenty bovine incisors were selected and grounded with 600-grit silicon paper to get an incisor platform, simulating a human molar incisal surface. The teeth were included i

23. All-ceramic and porcelain-fused-to-metal fixed partial dentures: a comparative study by 2D finite element analyses
All-ceramic fixed partial dentures (FPDs) have an esthetic approach for oral rehabilitation. However, metal-ceramic FPDs are best indicated in the posterior area where the follow-up studies found a lower failure rate. This 2D finite element study compared the stress distribution on 3-unit all-ceramic and metal-ceramic FPDs and identified the areas of major r
