Objective: To evaluate the predictability and success rate of implants installed in extraction sites, where the Guided Bone Regeneration (GBR) technique for bone preservation and implant placement was performed. Methods: This is a retrospective study, which included medical records of patients from the clinic of the Specialization in Implantology course from the educational institution, who underwent GBR in the tooth socket with indicated extraction, who delivered the tomographic exams, and had implants installed in these places, from 2007 to 2016. Forty-two participants were included in the research, totaling 55 sites divided into two groups: maxilla and mandible. Results: Two cases (3.7%) of non-bone formation were found after GBR, in the posterior region of the maxilla, with a success rate of 96.3% for predictability of implant placement in GBR sites. Of the 53 implants installed where there was sufficient bone formation, 3 (5.7%) did not return to the clinic and, therefore, 50 were evaluated, with 48 presenting clinical osseointegration with a success rate of 96%. Conclusion: There is predictability of GBR procedures in post-extraction sockets for the installation of osseointegrated implants.

Despite the success of osseointegrated implants, failures have increased significantly, associated with development of peri-implantitis. Multiple factors influence the peri-implant bone loss, including environmental and genetic causes. BMPs (Bone morphogenetic proteins) are growth factors that induce bone formation. FGF (fibroblast growth factors) and their receptors (FGFRs) play important roles by controlling the levels of cell proliferation, differentiation and migration. BMP/FGF relationship is responsible for promoting bone regeneration and bone loss. The aim of this study was to analyze the correlation between BMP4, FGF3, FGF10 and FGFR1 genes and peri-implant bone loss. Two hundred and fifteen volunteers, with 754 dental implants, were submitted to oral examination and divided in healthy group (n=129) and peri-implantitis group (n=86). Thirteen polymorphisms in BMP4, FGF3, FGF10 and FGFR1 genes were analyzed individually and in haplotype. The chi-square test correlated genotypes, allelic and haplotype frequencies. Values of p

O presente estudo teve como objetivo analisar a relação da condição periodontal, tendo como referência os índices de biofilme supragengival e de sangramento gengival, com a qualidade de vida dos pacientes infantis. Foram seleconadas crianças de 5 a 11 anos de idade, sistemicamente saudáveis, atendidas na clínica de odontopediatria da Universidade Salgado de Oliveira. Foram aplicados questionários de qualidade de vida CPQ 11-14 e 8-10 e o ECOHIS e realizado exames clínicos periodontais para obter os scores do índice de O´leary e de sangramento gengival. Os questionários foram respondidos pelo paciente voluntário ou, quando incapaz, pelo seu responsável. A qualidade de vida foi dicotomizada em baixa (G1- score < 15) e alta (G2- score > 15). Foi aplicado o teste t e do Qui-quadrado (p < 0,05). A amostra consistiu de 15 crianças. No G1, o índice de o’leary apresentou média 34,69 (±19,71) e no índice de sangramento a média foi de 13,80 (±5,79). No G2, a média para o’leary foi de 40,31 (±7,78) e para o índice de sangramento foi de 18,66 (±18,21). A qualidade de vida não apresentou diferença estatística para os indices de o’leary (p = 0,16; Teste t) e de sangramento gingival (p = 0,15; Teste t). O presente estudo demonstrou que os índices relacionados a biofilme dentário e a presença de gengivite não impactam na auto-percepção de qualidade de vida das crianças da amostra estudada. Objective: the aim of this study was to evaluate the relationship between the periodontal condition and the quality of life of pediatric patients, using as reference the supragingival biofilm and gingival bleeding indexes. Material and Methods: the study included systemically healthy children from 5 to 11 years of age, treated at the Pediatric Dentistry Clinic of Salgado de Oliveira University. Quality of life questionnaires CPQ 11-14 and 8-10 and ECOHIS were applied and periodontal clinical examinations were performed to obtain the O'Leary index and gingival bleeding index scores. The questionnaires were answered by the patient, or if unable, by the legal guardians. Quality of life was dichotomized as low (G1 score15). The t-test and the chi-square test (p

The aim of this case report was to describe an alternative treatment for the healing and maintenance of peri-implant mucosa in esthetical region. Managing the peri-implant soft tissue is one of the most challenging tasks in anterior implant esthetics, especially when replacing a failing tooth. However, not all patients underwent extraction, and immediate implant placement can receive loading, conducting to uncertain predictability. This is a case report that describes an alternative treatment for the healing and maintenance of the peri-implant mucosa in an esthetically significant region, through the use of a customized abutment to obtain an emergency profile when there is insufficient torque for immediate implant loading. The present technique was able to ensure not only healthy peri-implant soft and hard tissues, but also esthetic maintenance of the anterior region for immediate implant placement. This clinical case demonstrates a different manipulation technique from the peri-implant soft tissues in immediate implants of the esthetic region favoring the peri-implant health and clinical results, promoting treatment success, and patient satisfaction.

Subjects susceptible to chronic periodontitis (CP) show a high risk for the development of peiimplantitis (PI). Both diseases are multifactorial, presenting similarities in their pathophysiology and polygenic profile. MMP-13 (matrix metalloproteinases 13/ collagenase 3) is a collagenolytic enzyme, which expression is induced by TGF beta 3 (transforming growth factor type 3) in human gingival fibroblasts and inhibited by TIMP-2 (tissue inhibitor of metalloproteinase type 2). The aim of this study was to investigate the occurrence of peiimplantitis (PI) in subjects with history of chronic periodontitis (CP) and polymorphisms frequency in MMP13, TIMP2 and TGFB3 genes. One hundred and sixty-three volunteers received dental implant placement were submitted to oral and radiographic examination in order to identify past history of CP or presence of PI. Volunteers were divided into 4 groups: Control (without PI and CP, n=72), CP (with CP and without PI, n=28), PI (with PI and without CP, n=28) and diseased (with CP and PI, n=35). The chi-square test correlated genotypes in specific regions of MMP13 (rs2252070), TIMP2 (rs7501477) and TGFB3 (rs2268626) genes, considering the interaction between CP and PI. The results showed that volunteers with CP had 3.2 times more susceptibility to develop PI (p=0.0004) compared to those without CP. No significant association was observed in MMP13, TIMP2 and TGFB3 genes with CP or PI. CP is a risk factor to develop PI, however, there is no association of both diseases with polymorphisms in the MMP13, TIMP2 and TGFB3 genes. Resumo Indivíduos susceptíveis à periodontite crônica (CP) apresentam alto risco para o desenvolvimento de periimplantite (PI). Ambas doenças são multifatoriais e apresentam similaridades na patofisiologia e perfil poligênico. A MMP-13 (metaloproteinase da matriz tipo 13) é uma enzima colagenolítica cuja expressão é induzida por TGF beta 3 (fator transformador do crescimento tipo 3) nos fibroblastos gengivais humanos e inibida por TIMP-2 (inibidor tecidual de metaloproteinase tipo 2). O objetivo deste estudo foi investigar a ocorrência de periimplantite em sujeitos com periodontite crônica e a frequência dos polimorfismos nos genes MMP13, TIMP2 e TGFB3. Cento e sessenta e três voluntários submetidos à instalação de implantes endósseos foram analisados clínica e radiograficamente quanto à presença de histórico de CP e PI, sendo divididos em 4 grupos: Controle (sem história de CP e PI, n=72), CP (com CP e sem PI, n=28), PI (com PI e sem CP, n=28) e Doentes (com CP e PI, n=35). O teste do qui-quadrado correlacionou os genótipos nas regiões dos genes MMP13 (rs2252070), TIMP2 (rs7501477) e TGFB3 (rs2268626), considerando a interação entre CP e PI. Os resultados mostraram que voluntários com CP possuem 3.2 vezes mais chances de desenvolver PI (p=0.0004) comparados aos sem CP. Nenhuma associação significativa foi observada entre os genes MMP13, TIMP2 e TGFB3 e CP ou PI. A CP é um fator de risco ao desenvolvimento de PI, no entanto, não há associação entre ambas as doenças com polimorfismos nos genes MMP13, TIMP2 e TGFB3.

O objetivo do presente estudo é analisar o perfil socioeconômico dos pacientes atendidos na Clínica de Especialização em Im-plantodontia da Faculdade de Odontologia da Universidade Federal Fluminense - FOUFF. Para isto 31 pacientes da Clínica do Curso de Especialização em Implantodontia da FOUFF, acima de 18 anos responderam um questionário para analisar faixa etá-ria, gênero, grau de instrução, renda familiar, situação de propriedade de domicilio, se possuem plano de saúde e odontológico, e finalmente o porquê da procura pela FOUFF. Os resultados obtidos mostraram que os pacientes, a maioria mulheres, tem um grau de instrução em nível de ensino médio, além de possuírem uma renda familiar entre 2 a 4 salários, possuem casa própria quitada, plano de saúde, e procuraram a FOUFF pelo custo e qualidade do serviço oferecido. Foi possível concluir que apesar dos pacientes poderem arcar com o tratamento em uma clínica odontológica, eles procuram a FOUFF pela qualidade dos tratamentos prestados aos pacientes e pelo baixo custo.palavras-chave: perfil socioeconômico, Odontologia, Implantodontia.
