Abstract
Peri-implantitis is a plaque-associated pathological condition that occurs in tissues around dental implants. It is characterised by inflammation in the peri-implant mucosa and loss of supporting bone and shows a prevalence of around 22%. Peri-implantitis is linked with poor plaque control, history of periodontitis, diabetes and smoking. Non-surgical treatment protocols, with or without the adjunct use of antimicrobials has proven to be insufficient to control the disease progression. Surgical procedures for peri-implantitis treatment include two main approaches: resective and regenerative therapy. Open flap debridement and resective treatment are non-augmentative techniques that are indicated in the presence of a horizontal bone loss in aesthetically non-demanding areas. Various regenerative treatments for peri-implantitis, which include the use of bone grafts/bone substitutes with and without barrier membranes, have been evaluated and have demonstrated improved and stable long-term (> 3 years) clinical and radiographic outcomes.
