No. of bitstreams: 1 469538 - Texto Completo.pdf: 1770446 bytes, checksum: 90b8e8696e775e37ea2dd8f6aec011bc (MD5) Previous issue date: 2015-03-31 / Purpose: The purpose of this retrospective investigation was to evaluate, radiographically and clinically, a group of patients treated with immediate single-tooth placement, immediate restoration implants with a customized definitive abutment with a flapless approach in the area between both maxillary canines. Marginal bone level (MBL) and marginal bone level of neighboring teeth (MBLN) were assessed. Methods: A sample of 20 subjects received 20 tapered platform-switching implants using a minimally invasive surgery (trimodal approach). The mean age was 55.2 years (range 25 - 71 years), and the mean follow-up period was 2.2 years (range 12 - 48 months). Results: The overall treatment survival was 100%. There was no statistically significant difference between MBLN in both mesial and distal aspects, comparing baseline to final follow-up and between the four radiographs independently (i.e., at baseline, at 06 months, at 12 months, and at final follow-up). There was a statistically significant difference between MBL in both mesial and distal aspects at baseline and at final follow-up (p<0.05). Conclusion: Within the limitations of this study, it has demonstrated that the trimodal approach might offer an advantage in terms of marginal bone levels, especially in MBLN, in a mean follow-up time of 26 months. Additionally, reduced overall treatment time, one surgical intervention, and immediate esthetics can be obtained with 100% survival and success rates using a minimally invasive approach. / Objetivos: O objetivo desta investiga??o retrospectiva foi avaliar, radiograficamente e clinicamente, um grupo de pacientes tratados com instala??o imediata de implantes unit?rios, provis?rio imediato com um pilar prot?tico personalizado, com uma abordagem sem descolamento de retalho mucoperiostal na regi?o ?ntero superior. N?vel da crista ?ssea marginal e crista ?ssea marginal a n?vel dos dentes adjacentes foram avaliados. Materiais e m?todos: Uma amostra de 20 indiv?duos recebeu 20 implantes c?nicos com mudan?a de plataforma atrav?s de uma abordagem minimamente invasiva (abordagem trimodal). A m?dia de idade foi de 55,2 anos (variando de 25 a 71 anos) e o per?odo m?dio de acompanhamento foi de 2,2 anos (variando de 12 a 48 meses). Resultados: A taxa total de sobreviv?ncia dos implantes e coroas definitivas foi de 100%. N?o houve diferen?a estatisticamente significativa entre MBLN nas faces mesial e distal, comparando-se baseline ao controle final, assim como n?o houve entre as quatro radiografias independentemente (i.e. baseline, 6 meses, 12 meses e controle final). Houve diferen?a estatisticamente significativa entre MBL nas faces mesial e distal entre baseline e o controle final (p<0,05). Conclus?o: Dentro das limita??es deste estudo, demonstramos que a abordagem trimodal pode oferecer uma vantagem em termos de n?veis de crista ?ssea marginal, especialmente em MBLN, durante um per?odo m?dio de acompanhamento de 26 meses. Adicionalmente, reduzido tempo total de tratamento, apenas uma etapa cir?rgica e est?tica imediata podem ser obtidos com 100% de taxas de sobreviv?ncia e sucesso, utilizando uma abordagem minimamente invasiva.
