OUR EXPERIENCE REGARDING PERI-IMPLANTITIS

Although dental implants are most common prosthetic treatment used to replace missing tooth, it gained considerable importance over a decade owing to the availability of advanced techniques that can help in achieving a greater success rate and much better osseointegration. The chances that the implanted tooth can be rejected due to inflammation caused by oral microflora still persist. The term peri-implantitis is used to describe a destructive inflammatory process affecting the soft and hard tissues around osseo integrated implants, leads to the formation of a peri-implant pocket and loss of supporting bone. Predisposing factors are poor plaque control, inflammation, infection, smoking, diabetes and occlusal overload. It is diagnosed on the basis of clinical and radiographic interpretation and still no definitive criteria have been proposed for the diagnosis and treatment of peri-implantitis. However treatment can be both conservative and surgical. The cumulative interceptive supportive therapy protocol serves as good guide for the treatment of the peri-implantitis. Radiological examination it is very important pre- and post-operative assessment of implant surgery. Among all radiological methods, periapical radiography (PA) and cone beam computer tomography (CBCT) are common to asses post-operative peri-implant bone defects
