Prevalence of Periimplant Diseases.

PURPOSE To report the prevalence of periimplant diseases (ie, periimplant mucositis and periimplantitis). MATERIAL AND METHODS A literature search was performed in MEDLINE through PubMed database of the US National Library of Medicine for articles published until March 2018 using Medical Subject Heading (MeSH) search terms complemented by free terms and in different combinations. RESULTS A wide range of prevalences of periimplant diseases has been reported in the literature. Subject-based estimated weighted mean prevalences and ranges were reported to amount to 43% (range: 19%-65%) for periimplant mucositis and to 22% (range: 1%-47%) for periimplantitis. CONCLUSION Differences in case definitions impact on extent and severity of periimplant diseases and make comparisons among studies difficult. Convenience samples rather than randomly selected population samples are often analyzed to estimate prevalence of periimplant diseases. More recent studies report implant- and subject-based prevalences of periimplant diseases
