Abstract

Since the introduction of health insurance coverage for dental implants in 2014 for individuals aged 75 and older, the policy has expanded to cover up to two implants for those aged 65 and older. As a result, more than 600,000 health insurance-covered implant procedures are now performed annually at the local clinic. As of December 2024, South Korea has entered a super-aged society—with over 20% of the population aged 65 and older—it is expected that the number of dental implant procedures for the elderly will continue to increase. With the rise in implant procedures, the incidence of peri-implantitis is also growing. Initially described as a condition similar to periodontitis, peri-implantitis has since been systematically defined through ongoing research. At the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions, peri-implantitis was defined as“a pathological condition of dental plaque origin occurring in the tissues surroundings dental implants, characterized by inflammation of the mucosa surrounding the implant and subsequent progressive loss of sup-porting bone”. In response to this, the Korean Academy of Periodontology published a consensus report in 2024, which outlines a classification system for peri-implantitis based on bleeding on probing, probing depth, and the condition of surrounding alveolar bone. Treatment approaches for peri-implantitis are generally similar to those for periodontitis. Both non-surgical and surgical therapies aim to remove plaque and calculus, control inflam-mation, and promote reattachment of the peri-implant supporting tissues. The aim of this study is to review the latest periodontal perspectives on the treatment of peri-implantitis.
