The prevalence of peri-implant mucositis and peri-implantitis based on the World Workshop criteria: A systematic review and meta-analysis
Abstract
OBJECTIVES
This systematic review and meta-analysis aimed to estimate the worldwide prevalence of peri-implant mucositis and peri-implantitis using the 2017 World Workshop criteria.
DATA AND SOURCES
A comprehensive electronic search was performed in MEDLINE/PubMed, SCOPUS, EMBASE, and Web of Science databases. Cross-sectional studies assessing the prevalence of peri-implant diseases according to the 2017 Classification of Periodontal and Peri-Implant Diseases and Conditions classification were included. The risk of bias was assessed according to the Joanna Briggs Institute Critical Appraisal tool for Studies Reporting Prevalence Data. A mixed-effects model meta-analysis was performed.
STUDY SELECTION
Twenty out of 1979 studies were included. The weighted mean prevalence of peri-implant mucositis was 63.0% (CI: 57.6%-68.2%) at the patient level and 59.2% (CI: 55.8%-62.4%) at the implant level. Peri-implantitis was observed in 25.0% (CI: 21.1%-29.3%) of patients and 18.0% (CI: 15.8%-20.5%) of implants. Subgroup analyses revealed significant differences in the prevalence of peri-implant mucositis and peri-implantitis across continents. In non-smokers, the implant-level prevalence of peri-implant mucositis and peri-implantitis was 38.2% (CI: 33.4%-43.2%) and 5.2% (CI: 3.6%-7.5%), respectively. The risk of bias was high in 50%, moderate in 45%, and low in 5% of the studies.
CONCLUSIONS
Based on the 2017 World Workshop criteria, the prevalence of peri-implant diseases represents a…
