The use of dental implants has revolutionized the treatment of partially and fully edentulous patients today. While in many cases dental implants have been reported to achieve long-term success, these are also not immune from the complicationsincludingperi-implant mucositis and peri-implantitis. Peri-implantitis is an inflammatory process which involves bone loss around osseointegrated implant in function. The etiology of the disease has been attributed to bacterial infections, occlusal overload, surgical trauma, faulty or incorrect prosthetic design and/ or improper implant placement. Diagnosis is based on changes in colour of the gingiva, bleeding and probing depth of peri-implant pockets, suppuration, x-ray and gradual loss of bone height around the tooth. Treatment modalities will differ depending upon whether it is a case of periimplantmucositis or periimplantitis, Therapeutic objectives focus on control of infection, detoxification of the implant surface and regeneration of the alveolar bone. This review article gives a brief description of etiopathogenesis, diagnosis and various treatment options in the management of periimplant disease.
