Brief Summary

Peri-implantitis is defined as inflammation in the mucosa surrounding an oral implant with loss of supporting bone. The goals of peri-implantitis treatment are to resolve inflammation and to arrest the progression of disease. It is important to systematically gather information on the effect of surgical peri-implant treatment and to assess different protocols regarding chair-side maintenance of peri-implant tissue after surgery The aims of this clinical investigation are to evaluate the clinical, microbiological and radiographic outcomes of surgical treatment of peri-implantitis and to evaluate the efficacy of 2 supportive treatment protocols based on the use of titanium cyrettes or by the use of a flexible, biodegradable chitosan brush. Furthermore, to evaluate the impact of this therapy on selected biochemical markers associated with chronic inflammation and bone tissue destruction.
