Peri-implant mucositis
Peri-implant mucositis is defined as an inflammatory lesion of the peri-implant mucosa in the absence of continuing marginal bone loss.
The American Academy of Periodontology defines periāimplant mucositis as a disease in which inflammation of the soft tissues surrounding a dental implant is present without additional bone loss after the initial bone remodeling that may occur during healing following the surgical placement of the implant.
Peri-implant mucositis is largely accepted as the precursor of peri-implantitis and corresponds to gingivitis around natural teeth.
Important criteria to defining peri-implant mucositis are, the inflammation of mucosa surrounding an endosseous implant and the absence of continuing marginal peri-implant bone loss.
