title: Effect of history of periodontitis on implant success: meta-analysis and systematic review.
abstract: OBJECTIVE
  To determine if there is a relationship between history of periodontitis and dental implant success (used marginal bone loss [MBL] as the assessment criteria) and survival rates.
  
  
  METHODS
  PubMed search was performed in the period between 2002 and 2012. Studies qualified for the inclusion should have ≥5 years followed-up and reported the incidence of peri-implantitis and/or implant survival and/or MBL in patients with and without a history of periodontitis. A meta-analysis was performed using the random-effects model on the selected qualified articles.
  
  
  RESULTS
  All the 14 studies showed better implant survival rates for non-periodontitis patients' group. Six of 10 studies reported statistically significantly higher MBL and prevalence of peri-implantitis among periodontitis patients. Our meta-analysis did not find implant survival rates to be significantly lower among periodontitis patients (P = 0.99) but revealed a history of periodontitis to be significantly related to the higher prevalence of peri-implantitis (P < 0.001).
  
  
  CONCLUSIONS
  There is no difference, in terms of implant survival rate, between periodontitis and non-periodontitis patients. However, patients with history of periodontitis had lower implant success rate (more MBL and incidence of peri-implantitis) when compared with non-periodontitis patients.
