Classification of Peri-implantitis according to Froum and Rosen, 2012.

Stuart J. Froum, DDS & Paul S. Rosen, DMD, MS recently published an interesting paper on peri-implantitis. Peri-implantitis is a frequent problem that affects dental implants, specially if patient does not keep up with regular maintenance. Incidence of this type of complication ranges from 18-48% depending on the criteria adopted. Given the lack of standardization in the definition of peri-implantitis and peri-mucositis, the authors attempt to establish some guidelines in order to assist the clinician in the treatment of this type of complication. While still lacking a strong clinical validation, this classification system is definitely interesting.

Abstract from Pubmed

The lack of a standardized classification to differentiate the various degrees of peri-implantitis has resulted in confusion when interpreting the results of studies evaluating the prevalence, treatment, and outcomes of therapy. The purpose of this paper is to propose a classification for peri-implantitis based on the severity of the disease. A combination of bleeding on probing and/or suppuration, probing depth, and extent of radiographic bone loss around the implant is used to classify the severity of peri-implantitis into early, moderate, and advanced categories. The rationale and method of measurement for the classification are presented and discussed. This classification should help in communication between researchers and clinicians and thus provide a better understanding of peri-implantitis.
