Surgical treatment of peri-implantitis: Prognostic indicators of short-term results.

Resective peri-implantitis surgery seemed to reduce the amount of peri-implant inflammation. However, most of the sites continued to have BoP/suppuration. Thus, long-term maintenance and evaluation is warranted. The effect of treatment was reduced by some prognostic indicators such as the presence of suppuration prior to interception and peri-implant bone loss exceeding 7 mm.
