Newer proposed classification of periimplant defects: A critical update

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 definite 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. There is lack of a standard classification system to differentiate the various degrees of peri-implantitis, which produces dilemma in evaluating the stages clinical and radiological status, treatment and its outcome. Many classification has been proposed in medical literature with their pros and cons but still there is lack of standard classification system of implant defects and definite treatment protocol according to the same. The classification should be easy to use, clearly understandable and help in communication by clinicians of different speciality. This review aimed to introduce a classification system based on added clinical, and detailed radiological parameters with prognosis and staged treatment algorithms.
