13. 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

14. ANÃLISE DE SISTEMAS DE IMPLANTES DENTÃRIOS EM MANDÃBULAS EDÃNTULAS COM APLICAÃÃO DE CARREGAMENTO IMEDIATO / Study of the systems of dental implantations for edentulous mandibula with immediate load
The present study aimed at obtaining comparative elements among the guided systems of fixed complete denture with 4 osseointegrated implants with immediate loading, considering the importance of understanding the implant project as a process where biomaterials and biomechanics are assessed. The three-dimensional finite element method was used to analyze the

15. Loosening torque of prosthetic screws in implante-supported dentures with different fit levels / Torque de afrouxamento dos parafusos proteticos em proteses implanto-suportadas com diferentes niveis de desajuste
O objetivo neste estudo foi verificar a influência da composição da liga (titânio ou ouro) e do re-aperto no torque de afrouxamento dos parafusos protéticos, sob diferentes níveis de desajustes (adaptação passiva e desajuste) de próteses mandibulares implantosuportadas. Foram confeccionadas 10 próteses totais mandibulares implanto-suportadas e cria

16. Assessment of the tensile strength of hexagonal abutments using different cementing agents
The aim of this study was to assess the uniaxial tensile strength after thermal cycling in replicas of CeraOne®abutments (abutment and coping sets), using four types of cements (n = 10). A zinc phosphate cement (Fosfato de Zinco®/ SSW), a resin-modified glass ionomer cement (RelyX®luting / 3M-ESPE), a zinc oxide-eugenol cement (ZOE®/ SSW) and a zinc oxid

17. Electromyographic evaluation of mastication and swallowing in elderly individuals with mandibular fixed implant-supported prostheses
This study evaluated the effect of implant-supported oral rehabilitation in the mandible on the electromyographic activity during mastication and swallowing in edentulous elderly individuals. Fifteen patients aged more than 60 years were evaluated, being 10 females and 5 males. All patients were edentulous, wore removable complete dentures on both dental arc

18. Determinação das forças geradas por resinas acrílicas ativadas quimicamente durante o processo de transferência da posição de implantes Análise fotoelástica
The great number of laboratorial phases during implant-supported prostheses may contribute to deficient passivity fit. This misalignment could lead to screws relieves and also, the loss of osseointegration. Impression technique is an important step to be observed. Many materials and techniques are involved in this stage and acrylic resin is the most frequent

19. Analysis of alteration the number and diameter on stress transfer by protocols implant-supported prostheses / Analise das tensões na estrutura de suporte em protocolos implanto-suportados com alteração do numero e diametro das fixações
Este trabalho teve por objetivo quantificar e qualificar in vitro às tensões geradas pela da alteração do número e do diâmetro de implantes dentários em protocolos clássicos tipo Brånemark, em implantes fixados em modelo aproximado da região anterior da mandíbula, entre os forames mentonianos por meio da técnica da fotoelasticidade. Foram confecc

20. Evaluation of the resistance to the fracture of temporary fixed prostheses implant-supported varying the extension of the cantilever and the fiber type: glass fibers and poliaramid fibers / Avaliação da resistência à fratura de próteses fixas provisórias implanto-suportadas variando o comprimento do cantilever e o tipo de fibra: fibras de vidro e fibras de poli(aramida)
In the oral rehabilitator treatment, the provisory restorations have extremely importance. The resistance and durability of materials used in the execution are critical, especially in extended treatments and in vast toothless spaces. The goal of this work was to demonstrate the resistance and the types of fracture of specimens that simulate a fixed prosthesi

21. Avaliação da precisão da adaptação de próteses sobre implantes, fundidas em monobloco, com ligas de Ni-Cr e Co-Cr e em Ti cp, antes e após soldagem a laser e após a simulação da aplicação de cerâmica / Evaluation of the precision of fit of one-piece implant-retained and supported prostheses cast in Ni-Cr and Co-Cr alloys and Cp Ti, before and after laser welding and after simulated porcelain firing cycles
O objetivo deste estudo foi avaliar o assentamento passivo de supra-estruturas de próteses fixas implanto-suportadas de três elementos, fundidas em titânio comercialmente puro e em ligas à base de Ni-Cr e Co-Cr. Para esta análise foi utilizado o método de Sheffield (EISENMAN, 1997), e as leituras foram realizadas num microscópio óptico comparador (Ni

22. Avaliação da estética gengival em próteses unitárias implanto-suportadas em áreas de fissura alveolar enxertada / Evaluation of gingival esthetics in single implant-supported prostheses at the grafted cleft area.
With the increasing interest on the achievement of esthetics in implant-supported rehabilitations, the peri-implant soft tissues have been addressed in several investigations in Implantology. The congenital alveolar cleft is distinguished within this context because of the inherent esthetic impairment. This retrospective study assessed the gingival esthetics

23. Analise fotoelastica da distribuição de tensões induzidas por infra-estruturas implanto-suportadas apos soldagem a laser ou retificação de cilindros
This study evaluated two techniques indicated to obtain implant-supported fixed prostheses with satisfactory passive fit by means of photoelastic analysis. Two titanium casts groups were fabricated in a metallic master cast: Group I ? three frameworks fabricated by laser welded cylinder technique and Group II ? three frameworks cast in one-piece and submitte

24. A study of the correlation between marginal fit and tensions transmitted to implants by one-piece metal castings - a photoelastic analysis. / Estudo da correlação entre adaptação marginal e tensões transmitidas aos implantes por estruturas metálicas fundidas em monobloco - análise fotoelástica.
Obtaining a good marginal fit of the prosthetic components is one of the main obstacles to the success of rehabilitation with implant-supported prostheses. It is not clear, in the literature, which misfit levels are considered clinically acceptable, but it is known that the absence of a perfect and passive fit may cause inadequate tensions on the osseointegr
