Peri-implantitis is a serious inflammatory disease that develops around dental implants as a result of bacterial contamination and plaque accumulation on the implant surface. It affects both the surrounding gum tissue and the supporting bone, leading to progressive bone loss and, if left untreated, eventual implant failure. The condition often begins with mild symptoms such as redness, swelling, and bleeding of the gums, which can easily go unnoticed until significant damage has occurred. Poor oral hygiene, smoking, systemic conditions like diabetes, and irregular professional maintenance are major contributing factors. Traditional cleaning methods often fail to completely remove bacterial biofilm from the rough implant surface, making treatment challenging. As the infection progresses, the bone that anchors the implant deteriorates, compromising its stability and function. Early diagnosis and intervention are crucial to prevent irreversible damage. Effective management typically involves mechanical debridement, antiseptic or antibiotic therapy, and, in severe cases, surgical regeneration of lost bone.
