Definition and prevalence of peri-implant diseases.
OBJECTIVE
The aim of the current review was to describe the prevalence of peri-implant diseases including peri-implant mucositis and peri-implantitis.


METHODS
A MEDLINE search (PubMed) until December 2007 was conducted and different keywords related to the prevalence of peri-implant diseases were used. Cross-sectional and longitudinal studies including > or =50 implant-treated subjects exhibiting a function time of > or =5 years were considered.


CONCLUSIONS
The current review revealed that only a few studies provided data on the prevalence of peri-implant diseases. Cross-sectional studies on implant-treated subjects are rare and data from only two study samples were available. Peri-implant mucositis occurred in approximately 80% of the subjects and in 50% of the implants. Peri-implantitis was found in 28% and > or =56% of subjects and in 12% and 43% of implant sites.
