RESUMO
A Implantodontia tem se aperfeiçoado para aprimorar suas características biológicas e mecânicas. Contudo, o grande desafio atual é oferecer tratamento reabilitador estético, duradouro e que possibilite manutenção das estruturas circunvizinhas, tais como o tecido ósseo e a mucosa, onde esse equilíbrio depende de diversos fatores, entre eles, o tipo de interface protética. Os primeiros implantes desenvolvidos apresentavam uma junção externa por sobreposição hexagonal; no entanto, vários relatos clínicos descrevem complicações que resultaram em afrouxamento de parafusos e, até mesmo, fraturas de componentes protéticos e implantes. Para diminuir essas falhas mecânicas, foram desenvolvidas conexões de encaixe interno, sendo hexagonais, triangulares, octogonais ou cônicas. Com o advento e maior opção de interfaces protéticas para planejamento reabilitador, faz-se necessário melhor conhecimento sobre suas características biomecânicas e longevidade.
ABSTRACT
The implantology has been improved to enhance its biological and mechanical characteristics. However, the big challenge now is to offer rehabilitation treatment aesthetic, durable and enabling maintenance of surrounding structures such as bone and mucosa, where this balance depends on several factors among which the type of prosthetic interface. The first implants were developed by superimposing external hexagonal interface, however, several reports have described clinical complications that resulted in loosening of screws and even fractures implants and prosthetic components. To reduce these failures were developed mechanicals connections internal fitting, being hexagonal, triangular, octagonal or conical. With the advent and greater choice of interfaces for prosthetic rehabilitation planning it is necessary to better knowledge about their biomechanical characteristics and longevity.
