Peri-implantitis is a condition defined by progressive bone loss mediated by an inflammatory response to pathogenic bacterial colonization of the peri-implant pocket. This disorder follows an acceleratory and non-linear pattern of progression. Peri-implantitis lesions are about two times larger than periodontitis lesions and are dominated by plasma cells. Altogether, the prognosis of implants with peri-implantitis tends to be poorer than the prognosis of teeth with periodontitis.
