Resumo(s)
Introdução: Implantes imediatos são colocados após a extracção dentária. As vantagens são a possível diminuição do tempo de tratamento, do número de cirurgias e da reabsorção óssea que, possivelmente, melhora a estética final. As desvantagens poderão ser a dificuldade em atingir a estabilidade primária e o risco aumentado de infeções e complicações. Objetivos: Responder à questão PICO: “Em pacientes que precisem de reabilitação implantar na zona anterior de canino a canino com recurso à técnica imediata, apresentará esta uma taxa de sucesso superior à técnica convencional?” Materiais e Métodos: Foi realizada uma pesquisa nas bases de dados MEDLINE e Cochrane Database of Systematic Reviews no mês de Dezembro de 2015. As palavras chave foram: immediate implant anterior OR immediate implant placement anterior OR immediate implant anterior AND extraction socket OR immediate implant anterior installation OR immediate implant esthetic. Encontraram-se 992 artigos e aplicaram-se critérios de inclusão e exclusão. Foram seleccionados 161 após a leitura do título e abstract. No final, incluiram-se 15 artigos: 5 estudos retrospetivos e 10 prospetivos. Resultados: Foram avaliados 15 estudos, 461 pacientes, 557 implantes com um follow-up médio de 29 meses, apresentando uma taxa de sucesso/sobrevivência médias de 99,5% 99,4%, respectivamente. Avaliou-se ainda as complicações, a existência de carga imediata não funcional, a colocação de membrana, a perda óssea e a estética final. Os resultados dos parâmetros avaliados são semelhantes aos obtidos pela técnica convencional. Conclusão: A colocação de implantes imediatos na zona anterior, de canino a canino, parece ser uma técnica fiável e previsível, no entanto, a análise de viés dos artigos revelou que estes ainda não possuem evidência científica necessária para se recomendar a colocação de implantes imediatos na zona anterior de canino a canino como prática clínica usual.
Introduction: Immediate implants are placed in the same appointment as tooth extraction. The advantages may be treatment time, number of surgeries and dimineshed bone reabsortion, possibly improving esthetic results. The possible disadvantages may be difficulties in achieving primary stability and an increased risk of infection and complications. Objectives: Answser the PICO question: “In pacients who need implant treatment in anterior zone, from canine to canine, will immediate implants present a sucess rate superior to convenional techique?” Materials and Methods: Extensive literature review of the Cochrane Database of Systematic Reviews and MEDLINE electronic databases up to December 2015 identified eligible studies. The key words were immediate implant anterior OR immediate implant placement anterior OR immediate implant anterior AND extraction socket OR immediate implant anterior installation OR immediate implant esthetic, it wasn’t apply any filters for not loose any result of interest. It was found 992 articles, and it was applied inclusion and exclusion criteria. It was selected 161 after reading title and abstract. In the end, this systematic review included 15 articles: 5 and 10 was retrospective and prospective studies, respectively. Results: It was evaluated 15 studies, 461 pacients, 557 implants with a mean follow-up of 29 months, presenting a sucess/survival rate of 99,5% and 99,4%, respectively. Complications, immediate non function loading, grafting materials, bone loss and final esthetic were also evaluated. The results show that all the availed parameters are similar to the results of convencional technique. Conclusion: Immediate implants in anterior zone seems to be a fiable and predictable technique. The risk of bias is very high, so there is no cientific evidence to recommend the use of immediate implants in the anterior zone as an usual clinical pratice.
