Peri-implantitis is a serious plaque-associated inflammatory condition that affects the soft and hard tissues surrounding dental implants, leading to progressive bone loss and potential implant failure. It usually develops due to the accumulation of bacterial biofilm around the implant surface, which triggers an inflammatory response in the surrounding gum and bone tissue. Poor oral hygiene, inadequate plaque control, and irregular professional maintenance visits significantly increase the risk of developing peri-implantitis. Once established, the condition can be difficult to manage because conventional cleaning methods—such as mechanical debridement or chemical disinfection—often fail to completely remove biofilm from the complex implant surface. Additionally, aggressive cleaning techniques may damage the implant’s delicate surface, compromising its ability to integrate with the surrounding bone. Therefore, there is an increasing need for a safe, effective, and minimally invasive approach to decontaminate implant surfaces and control infection.
