Definitions of peri-implant mucositis and peri-implantitis vary in the literature, and no clear criteria have been
established for the diagnosis and treatment of such disorders. This study proposes a classification for peri-implant mucositis
and peri-implantitis based on the severity of the disease, using a combination of peri-implant clinical and radiological
parameters to classify severity into several stages (Stage 0A and 0B = peri-implant mucositis, and Stage I to IV = periimplantitis).
Following a review of the literature on the subject and justification of the proposed peri-implant disease classification,
the latter aims to facilitate professional communication and data collection for research and community health
