Implant therapy in partially edentulous, periodontally compromised patients: a review

Aim: The purpose of the present study was to perform a review using a systematic approach to evaluate the long-term (>= 5 years) success of implants placed in partially edentulous patients with a history of periodontitis as evidenced by loss of supporting bone and implant loss. Material & Methos: An electronic search of the National Library of Medicine, Washington DC (Medline-PubMed) was performed using specific search terms to identify studies assessing, in periodontitis patients, the success of implants with regard to bone level outcomes. Search was performed on abstracts registered up to October 2003. Results: The searches identified 877 abstracts. Titles and abstracts were independently screened by two reviewers (G.A.W. & K.M.B.) to identify publications that met the inclusion criteria. Review of these abstracts resulted in 13 publications for detailed review. These papers were reviewed by the three authors. Finally four papers which met the criteria of eligibility were independently selected by the three reviewers. Conclusion: Based on the limited data, it seems justified to conclude that the outcome of implant therapy in periodontitis patients may be different compared to individuals without such a history as evidenced by loss of supporting bone and implant loss.
