title: Prevalence of peri-implant inflammatory disease in patients with a history of periodontal disease who receive supportive periodontal therapy.
abstract: OBJECTIVE
  To describe the status of implants in periodontally compromised patients who regularly receive supportive periodontal therapy (SPT) and to determine the factors associated to peri-implant inflammatory disease in those patients.
  
  
  METHODS
  Clinical and radiographic data of implants in periodontal patients who, after being treated and included in a SPT programme, wore implant prostheses for at least 6 months were recorded. The implants were classified according to the criteria of the 6th European Workshop on Periodontology in health, mucositis and peri-implantitis. Logistic regression analysis was performed to analyse the individual and adjusted effects of each study variable on mucositis or peri-implantitis, using SUDAAN to account for clustering (multiple implants within the patient).
  
  
  RESULTS
  A total of 786 implants were placed in 239 patients. At patient level, 60.3%, 24.7% and 15.1% were classified as healthy, mucositis and peri-implantitis patients, respectively. At implant level, the respective percentages were 77.4%, 12.8% and 9.8%. For mucositis, at implant level, the adjusted ORs indicate a significant association with plaque index (P = 0.050), type of periodontitis (P = 0.030) and location (P = 0.045). For peri-implantitis, the adjusted ORs indicate a significant association with plaque index (P < 0.001) and location (P = 0.002).
  
  
  CONCLUSIONS
  The prevalence of peri-implant inflammatory disease in periodontal patients who regularly undergo SPT is clinically significant. The factors associated with peri-implant inflammatory disease were plaque index and implant location, and mucositis was also affected by the type of periodontitis the patient had.
