LOPES, Alex Casati; REZENDE, Carlos Eduardo Edwards; FERNANDES, Mariana dos Santos  and  WEINFELD, Ilan. Bacterial leakage of the implant-abutment interface: what the implantologist should know. RGO, Rev. gaúch. odontol. (Online) [online]. 2010, vol.58, n.2, pp. 239-242. ISSN 1981-8637.

Many studies have shown high rates of successful oral rehabilitation with implants. However, complications may occur immediately after the implant is placed or some time later, when the prosthesis has already been used for some time. These complications may lead to implant failure. Late failures can happen in situations where the osseointegration of a previously stable and functional implant is lost because of an overload and/or an infection. One of the causes of infection is the infiltration of bacteria in failures present in the implant-abutment interface. With this in mind, the purpose of this study was to address the infiltration of liquids and bacteria inside the implant due to failures in the implant-abutment interface based on a literature review. In conclusion, despite the development of new implants and abutments and the attempts of some authors to seal microfissures, bacterial infiltration in the implant-abutment interface still occurred.
