25. Relação da distância interimplantar e altura do ponto de contato na formação de papilas gengivais: estudo em cães / Influence of interimplantar distance and height from the point of contact in the formation of gingival papilae: a study in dogs
Os implantes dentais são considerados uma modalidade de tratamento bastante previsível para a reposição de dentes perdidos. Os implantes osseointegráveis principalmente quando colocados em regiões anteriores devem oferecer, além de excelente função, ótima estética, e fonética. Sendo que o critério para o sucesso envolve o estabelecimento do cont

26. Mechanisms underlying the differentiation of stem cells from human exfoliated deciduous teeth (SHED) into odontoblasts and endothelial cells / Mecanismos envolvidos na diferenciação de células-tronco de dentes decíduos exfoliados humanos (SHED) em odontoblastos e células endoteliais
Dental pulp tissue engineering aims to replace the inflamed or necrotic pulp by a healthy and functionally competent tissue able to form new dentin in order to repair lost structure. The purposes of this work were: to evaluate the differentiation ability of stem cells from human exfoliated deciduous teeth (SHED) into functional odontoblasts, showing the form

27. In vivo qualitative analysis of the biocompatibility of different cyanoacrylate-based adhesives
Cyanocrylates have been widely used in the medical and dental fields for several years. In Dentistry, cyanoacrylates have been used for suturing, pulp capping, as retrofilling material in endodontic surgeries, and as cervical plug for pulpless teeth bleaching. The biocompatibility of these adhesives has been the topic of many researches and subcutaneous impl

28. Avaliação do comportamento clinico e radiografico do cimento de fosfato de calcio como material de preenchimento em cirurgia de elevação do assoalho seio maxilar / Evaluation of clinical and radiographic of the calcium phosphate cement as fulfilling material in sinus lift surery
Implant placement in the posterior maxilla is frequently challenged by resorbed alveolar processes due to a combination of maxillary sinus pneumatization, the effects of periodontal disease and the physiological bone resorption following tooth extractions. The sinus floor augmentation surgery has been performed since 1980 with the purpose of increasing bone

29. Os Centros de Especialidades Odontológicas como suporte da atenção básica: uma avaliação na perspectiva da integralidade
The public dental services in Brazil were limited, practically, to the basic care, so that the specialized services acted, up to 2002, no more than 3,5% of the total of clinical procedures. That lower offer reveals the difficulty of continuity of the attention, that is, the comprehensiveness in the assistance, particulary, the reference and counter-reference

30. Tensile strenght of NiCr crowns cemented upon usinated titanium alloy abutments, LASER irradiated or not / Resistência à remoção por tração de coroas NiCr cimentadas sobre munhões usinados em liga de titânio, irradiados ou não por LASER
By means of tensile essays, NiCr total crowns were removed from usinated tronco-conical abutments composed by an Ti-6Al-4V alloy; the performance of 4 cementig agents (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelayX Luting 2 composite resin and Panavia 21 TC special acrylic resin) was evaluated. Among a total of 50 abutments, 40 were used

31. Efeito do numero de ciclos de união e separação dos componentes sobre a retenção de sistemas de encaixes para overdentures / Retention force and fatigue strength of overdenture attachment system
The aim of the present study was to evaluate the effect of the number of insertion and removal cycles on retention force of four Overdenture bar-clip attachment systems. Sample included 40 specimens which were assigned to 4 groups (n=10): 1- Conexão Sistemas de Prótese (polymeric clip); 2- Sterngold-Implamed (polymeric clip); 3- 3i- Implant innovation (met

32. Análise das características microscópicas do tecido peri-implantar em diferentes tipos de conexão protética em implantes / Comparative analysis of peri-implant soft tissue microscopic characteristics between two types of implant-prosthetic connections
The microscopic characteristics of the peri-implant soft tissue around different types of prosthetic interface for implants has been evaluated by means of histological analysis, 10 patients carrying implant supported bridges has been selected on the basis of the inclusion criteria and divided in two groups, with group I formed by five patients with external

33. Efeito do tipo de revestimento estetico e da eletroerosão sobre a desadaptação de infra-estruturas metalicas implantossuportadas / Influence of vennering material and spark erosion on marginal misfit of implant-suported frameworks
The demand for a passive fit of frameworks for osseointegrated endousseous implants abutments is well known, because the tightening of an inaccurate framework to the abutments can transmit stress to the bone-metal interface. The purpose of the present study was to evaluate the influence of the veneering application and porcelain firing cycle on the misfit le

34. 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

35. Avaliação da deformação gerada nos componentes intermediários de prótese fixa implanto-suportada com diferentes alturas, com a utilização de extensômetros lineares elétricos / Assessment of the deformation of the generated in different heights of abutments of mandibular implant-supported prosthesis, with the use of strain Gauges
Em prótese total fixa implanto-suportada as diferentes alturas dos intermediários traduzem-se em diferentes braços de alavanca aos quais os implantes são submetidos levando a um efeito de deformação dos componentes que até o momento é desconhecido. O objetivo deste trabalho foi verificar a deformação gerada em diferentes alturas de componentes inte

36. In vitro and in vivo electrochemical studies of nickel-chromium-molybdenum-titanium alloy applied to oral implant suprastructures / Estudos eletroquímicos in vitro e in vivo da liga níquelcromomolibdênio titânio aplicada em supraestruturas de implantes orais
The electrochemical behavior of the nickel-chromium-molybdenum-titanium (Ni-Cr-Mo-Ti) alloy was studied and compared to a gold-platinum-palladium (Au-Pt-Pd) alloy in 0.15 mol.L -1 NaCl medium at 36.5ºC. In vitro studies also involved the electrochemical titanium characterization since these alloys are employed in osseointegrated implant suprastructures. In
