Peri-implant mucositis Peri-implant mucositis is characterised by an inflammatory lesion in the soft tissues surrounding an implant in the absence of loss of supporting bone. The lesion is located lateral to the junctional/pocket epithelium but does not extend into the supracrestal connective tissue zone “apical” of the junctional/ pocket epithelium. The main clinical characteristic of peri-implant mucositis is bleeding on gentle probing, while other clinical signs of inflammation – such as erythema and swelling – may also occur. An increase in probing depth is often observed in the presence of peri-implant mucositis because of swelling or a decrease in probing resistance. There is strong evidence that plaque is the aetiological factor involved in peri-implant mucositis. There is also evidence that peri- implant-mucositis lesions can resolve after the reinstitution of plaque-control procedures.
Case definition of peri-implant mucositis in day-to-day clinical practice:
• bleeding and/or suppuration on gentle probing; • no bone loss.
