There are three types of implant-related disease:
Implant-related mucositis affects the soft gum tissue immediately surrounding the implant. This inflammation is caused by plaque and characterized by swollen gums that bleed when probed. Dentists treat this condition the same way they treat plaque.
In peri-implantitis, inflammation of the soft tissues around the implant is accompanied by the progressive loss of supporting bone. Peri-implantitis is associated with poor plaque control and occurs in people with a history of severe periodontitis. Dentists treat it the same way they treat periodontitis.
