Treatment of peri-implantitis: surgical therapeutic approaches based on peri-implantitis defects.

Peri-implantitis is a frequently occurring inflammatory disease mediated by bacterial infection that results in the loss of supporting bone. Peri-implantitis should be treated immediately, but there is a lack of evidence regarding the most effective therapeutic interventions. Nonsurgical periodontics may be the treatment of choice in cases of peri-implant mucositis or if the patient has medical contraindications or refuses to consent to more appropriate treatment. Peri-implantitis defects will dictate the therapeutic approach and present a guideline for relative clinical management. The suggested therapeutic solutions are derived from clinical experience and are meant to be a useful guide.
