Periodontitis as a potential risk factor for peri-implantitis.
OBJECTIVE
To review the literature regarding the possible association between a previous history of periodontitis and peri-implantitis.


METHODS
A search of MEDLINE as well as a manual search of articles were conducted. Publications and articles accepted for publication up to January 2008 were included.


RESULTS
Out of 951 papers retrieved, a total of three papers were selected for the review. Thus, the available evidence for an association between periodontitis and peri-implantitis is scarce.


CONCLUSIONS
Based on three studies with a limited number of patients and considerable variations in study design, different definitions of periodontitis, and confounding variables like smoking that not been accounted for, this systematic review indicates that subjects with a history of periodontitis may be at greater risk for peri-implant infections. It should, however, be stressed that the data to support this conclusion are not very robust.
