Peri-implantitis
Pronunciation: peh-ree-im-plan-TY-tis
An inflammatory condition affecting both the soft and hard tissues surrounding an osseointegrated dental implant, resulting in progressive bone loss.
Full Definition
Peri-implantitis is characterised by bleeding on probing, suppuration, and radiographic bone loss beyond the expected remodelling at the implant neck. It is distinguished from peri-implant mucositis by the involvement of the supporting bone. The 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases established standardized diagnostic criteria. Editors must hyphenate 'peri-implantitis' consistently and distinguish it from 'periodontitis', which affects natural teeth, as the two conditions share clinical features but have different aetiological and management considerations.
Usage
Usage note: Always hyphenate: 'peri-implantitis', not 'periimplantitis'. The hyphen is retained consistently in the indexed literature and in EFP/AAP classification documents.
