25. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

26. 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

27. 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

28. Análise de tensões pelo método de elementos finitos em próteses dento-implanto-suportadas: Influência da extensão da prótese e diâmetro do implante
The impossibility of using implants as independent supports of the prosthesis in the patients treatment partially edentulous, mainly in cases of anatomical limitations, makes possible for the implants to be added to the natural teeth, characterizing the tooth-implant-supported prosthesis. The conditions for it to be a viable prosthetic option, justifies know

29. 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

30. 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

31. 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

32. 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

33. Fracture of abutment screw supporting a cemented implant-retained prosthesis with external hexagon connection: a case report with sem evaluation
One of the causes of implant failures in cemented implant-retained prostheses is the fracture of abutment screw or UCLA abutment. This article reports a case of simultaneous fracture of two UCLA abutments screws occurring in an implant-supported prosthesis placed in the mandibular molar region. The fractured structures were examined under scanning electron m

34. Determinação de níveis ótimos de passividade em prótese sobre implante em função da deformação dos intermediários / Optimum passivity levels of implant prosthesis according to abutment deformation
Passive fit has been considered one of the most important requirements for the success of implant supported prostheses. This in vitro study investigated the abutment deformation of an implant-supported prosthesis after screw tightening of palladium-silver and cobalt-chromium prosthetic cylinder. A master model was used to simulate a human mandible with five

35. Photoelastic analysis of stress transmitted from implant-supported frameworks achieved by cilinders lutingand laser welding techniques before and after eletric discharge machining / Analise fotoelastica das tensões induzidas por infra-estruturas implanto-suportadas obtidas pelas tecnicas de cimentação dos cilindros e soldagem a laser, antes e apos eletroerosão
The purpose of the study was to evaluate the passive fit of fixed implantsupported prothesis titanium frameworks, through photoelastic stress analysis. Two frameworks welded in commercially pure titanium (Tritan® -Dentaurum -Germany) were fabricated by two methods based on a metal model composed of five analogous Micro-Unit (Conexão -São Paulo): Framework

36. Comparisions of maximum bite force with mandibular conventional dentures and implant-supported overdentures / "Estudo comparativo da intensidade da força de mordida de próteses totais convencionais e overdentures inferiores retidas por sistema barra/clip sobre implantes"
The objective of the research was to compare the intensity of the bite force, using an gnatodinamometer in edentulous patients that use superior complete denture and inferior Overdentures retained by clip bar system and to evaluate general satisfaction of these patients after the rehabilitation with the prostheses on implants through a questionnaire. The stu
