Surgical Treatment of Periimplantitis in Patients With Risk Factors

Surgical Treatment of Periimplantitis in Patients With Risk Factors: Heavy Smokers, Type 2 Diabetic and Chronic Periodontitis Patients

This study evaluates clinical and radiographic parameters among riks factor groups in patients with periimplantitis. This study will also treat and evaluate the patients response before and after surgical treatment.

Periimplantitis (PI) is an inflammatory process that results in tissue attachment bone loss around the implant. Periodontal disease, smoke habit and type 2diabetes mellitus have been recognized as potential risk factor indicators that might lead to complications establishment and progression around dental implants. PI treatment predictability has been shown limited and influenced by factors not totally clarified. The aim of this study is to evaluate the reparative response after PI surgical treatment at clinical and radiographic levelsin risk factors patients: type 2 diabetes mellitus, smokers and chronic periodontal disease.
