25. Avaliação clínica e histológica de implantes imediatos e tardios associados a matriz óssea xenógena e membranas: acompanhamento de 10 anos / Clinical and histological evaluation of immediate and late implants associated with xenogeneous bone matrix and membranes: 10 years follow-up
The aim of this research is to evaluate the clinical and histological findings of installed implants immediately after exodontics (Group 1) and later after the alveolus regeneration (Group 2). In both groups, xenogeneous lyophilized bone matrix was used in association with resorbable bovine collagen membrane and/or nonresorbable expanded politetrafluoretane

26. Clinical and histopathological analysis of intramucosal zirconia inserts used for improving maxillary denture retention
Intramucosal inserts made of zirconia ceramic have been used for the rehabilitation of edentulous patients. This study aimed to follow up on patients with complete dentures having intramucosal zirconia inserts and to perform a histological analysis of biopsies of the epithelium surrounding the inserts. Twelve 31-66-year-old subjects of both genders received

27. Avaliação da expressão imunoistoquímica das proteínas β-Catenina e Wnt-5a em carcinoma escamocelular de boca.
Oral squamous cell carcinoma (OSCC) is the most common histological form of head and neck cancer. Because of the highly aggressive evolution of some tumors, more knowledge is needed about its biological behavior, which may be achieved using immunohistochemical markers. Wnt-5a, of the Wnt family, is frequently upregulated in certain human cancers, and it can

28. Comparative study of single and multislice computed tomography for assessment of the mandibular canal
OBJECTIVE: The purpose of this study was to evaluate the accuracy of relative measurements from the roof of the mandibular canal to the alveolar crest in multislice (multidetector) computed tomography (MDCT) and single-slice computed tomography (SSCT). MATERIAL AND METHODS: The sample consisted of 26 printed CT films (7 SSCT and 19 MDCT) from the files of th

29. Avaliação da aplicabilidade clínica do ultra-som e pontas CVDentus na cirurgia de levantamento do assoalho do seio maxilar
A perda parcial ou total de dentes da região posterior do processo alveolar do osso maxilar leva a pneumatização dos seios maxilares, fazendo com que o osso seja remodelado, dificultando a reabilitação através de próteses sobre implantes. A cirurgia de elevação do assoalho do seio maxilar (sinus lift) foi desenvolvida para superar este problema. A p

30. Análise da distribuição das tensões nas estruturas de suporte de overdentures, rebordo residual e implantes, com sistema de conexão de coroas cônicas (Syncone-Dentsply). / Analysis of the tensions distribution in the structures of overdentures support, residual alveolar ridge and implants, with connection of conical crowns system (Syncone-Dentsply)
O sistema de osseointegração desenvolvido por Branemark revolucionou o campo das reabilitações protéticas, incentivando os profissionais a indicar e realizar próteses do tipo overdentures. Estes dispositivos representam uma ótima alternativa para solucionar os problemas dos pacientes desdentados, insatisfeitos por diversos fatores. Várias são as ass

31. Evaluation of ridge preservation after castor bean alloplastic polymer bone graft post-extraction sockets of rats a radiographical and histological study / Avaliação da manutenção da dimensão de rebordo alveolar após enxerto aloplástico de composto ósseo de rícino pós-extração dental em rato, estudo radiográfico e histológico
The aim of this work is to study the behavior of the castor bean alloplastic polymer bone graft on ridge preservation. The dental extraction cicatrization process is an atrophy process. There are preventive techniques for maintenance of the dimensions of the alveolar ridge. These techniques are: dental implant, guided bone regeneration, bone graft and the co

32. "Análise comparativa, pelo método dos elementos finitos bidimensional, das tensões geradas nas estruturas de suporte de prótese parcial removível de extremidade livre inferior, em rebordo horizontal e descendente-ascendente" / A two-dimensional finite element analysis of the stress distribution in the supporting structures of a distal extension base removable partial denture over a horizontal and descending/ascending residual ridge.
This study is a two-dimensional finite element analysis (FEA) of the stress distributionin the supporting structures compact and cancellous bone; periodontal ligament and oral mucosa for a distal extension base removable partial denture (RPD) modeled on mandibular dental archs with two residual ridge forms: horizontal and descending-ascending. The two

33. Estudo imunohistoquimico das citoqueratinas, do indice de proliferação celular e da resposta inflamatoria na paracoccidioidomicose bucal
Paracoccidioidomycosis (Pmycosis) is a common systemic mycosis in Latin America, with variable clinical presentation. The chronic form frequently involves the oral mucosa, showing multiple moriform like lesions. Microscopically, oral Pmycosis is cha_acterized by pseudoepitheliomatous hyperplasia (PEH), and granulomatous inflammatory response, besides polimor

34. Avaliação do tratamento de defeitos de rebordo alveolar com regeneração ossea guiada : estudo histometrico em cães
The aim of the present study was to histometrically evaluate the bone regeneration obtained in surgically created ridge defects in dogs treated or not with guided bone regeneration. Nine female mongrel dogs were included. All molars in the mandible were extracted. After three months, a bone defect was surgically created bilaterally in the mandible with dimen

35. Eficacia do exame clinico e tomografia computadorizada na detecção de metastases linfonodais e da linfocintilografia na avaliação da drenagem linfatica em carcinoma espinocelular de boca e orofaringe
Clinical examination alone is not enough to establish the true extenuation of local involvement and regional metastases in oral and oropharyngeal carcinomas. The objectives of this work were to evaluate the sensitivity and specificity of computed tomography (CT) to determine regional metastases, and to verify the migration of 99mTc-Dextran by Iymphoscintigra

36. Avaliação da localização do canal mandibular por meios de exames tomografico (linear, Pluridirecional e computadorizados de alta resolução) em comparação com a anatomia ossea topografica
The aim of this study was compare the vertical and horizontal dimensions in images obtained from dried skulls by means of three types of tomographic exams: linear; transversal pleuridirectional panoramic and computerized high resolution with bone topographic anatomy. The selection of a precise radiographic method proved to be of great importance in the plann
