RESUMO
Peri-implantitis, characterized by inflammation of tissues around implants and gradual loss of supporting bone tissue, has become one of the main causes for implant failure. Thoroughly removing the plaque biofilm on the implant surface is the first principle in the treatment of peri-implantitis. For this reason, various decontamination methods have been proposed, which can be divided into 2 categories: Removing biofilm and killing microorganisms according to the effect of plaque biofilm on the implant surface. However, at present, there is no decontamination method that can completely remove the plaque biofilm on the implant surface, and it lacks of clinical recommended guidelines. To understand the advantages and disadvantages, effectiveness and safety for different implant surface decontamination methods is of great significance to guide the clinical selection for peri-implantitis treatment.
