Dental implant prognosis in periodontally compromised partially edentulous patients

Abstract

Objectives: The aim to look through the literature published in the recent 10 years regarding the possible association between a previous history of periodontitis, dental implant survival rates and prevalence of peri-implantitis. Methods: The database on PubMed was searched from 2002 January 1st up to 2012 January 1st. Cross –sectional and longitudinal studies reporting on outcomes of peri-implantitis and/or implant survival in patients with a history of periodontitis compared with non-periodontitis patients, including ≥10 implanttreated subjects exhibiting a function time of ≥5years. Results: The search provided 2314 potentially relevant titles and abstracts. After screening the titles and abstracts, 34 full papers were selected for full-text reading. Finally 19 acticles full-filled the selection criteria and were included to the review. 13 studies compare survival rates among periodontally compromised and non-periodontitis patient. All of them showed better implant survival rates for non-periodontitis sub-group compared with periodontally compromised patient. However, a statistically significant difference was only found in 2 studies indicating significantly higher survival rates in periodontally healthy patient. Totally 8 studies reported lower occurrence of peri-implantitis in the non-periodontitis patients in comparison with periodontitis patients. A statistically significant difference was reported in 6 out of the studies included. Conclusions: The survival rates are high and comparable to non-periodontitis patients. However, the incidence of peri-implantitis is higher among this subgroup of patients. Implant treatment appears to be a good treatment option even in periodontally compromised patients. Patients with a history of periodontitis should be informed that they are at higher risk for peri-implant diseases.
