Biomechanical study of prosthetic interfaces: A literature review

Angelo Marcelo Tirado dos Santos

Implantology has improved its biological and mechanical characteristics. However, the big challenge nowadays is to offer esthetic rehabilitation treatment that is durable and, at the same time, enables maintenance of the surrounding structures, such as bone and mucosa, where this balance depends on several factors, including 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, as well as fractures of implants and prosthetic components. To reduce these failures, mechanical connections — hexagonal, triangular, octagonal or conical — were developed with internal fitting. With the advent and the several options of prosthetic interfaces available for rehabilitation planning, greater knowledge about their biomechanical characteristics and longevity is required.
