AB  - BACKGROUND: The pathophysiology and pathology of peri-implantitis remain unclear; 
      however, its similarity to periodontitis has been described. The evaluation of 
      peri-implant tissue and the diagnostic criteria of peri-implant disease are not 
      currently standardized as they are for periodontitis. In this study, we evaluated 
      clinical parameters during the implant maintenance period to determine 
      significant correlations between these parameters. METHODS: We examined 55 
      implant patients at the time of maintenance visits between April and September 
      2016 and classified patients into a healthy group (H) and a 
      history-of-periodontitis group (HP). For each implant, we evaluated the modified 
      plaque index, probing pocket depth, and bleeding on probing as clinical 
      parameters. Statistical analyses were performed with Spearman's rank correlation 
      coefficient. RESULTS: A total of 130 implants were assessed. The mean time since 
      implant placement was 6 years and 6 months. The prevalence of implant-based 
      peri-implantitis was 10.8% of all the implants. All cases of implant-based 
      peri-implantitis came from the HP group, and many were present in patients with a 
      history of severe periodontitis. The probing pocket depth around the implant was 
      significantly greater in the HP group than in the H group. We found weak positive 
      correlations between the probing pocket depth and bleeding on probing (r (s) 
       = 0.401, p < 0.05) in the H group and between the probing pocket depth and 
      bleeding on probing (r (s)  = 0.241, p < 0.05) and the modified plaque index (r 
      (s)  = 0.228, p < 0.05) in the HP group. CONCLUSIONS: Our findings suggest that 
      probing pocket depth and bleeding on probing as clinical parameters are important 
      indicators for the diagnosis of peri-implant disease during the maintenance 
      period among healthy and history-of-periodontitis groups.
