Peri‐Implant Conditions During Supportive Periodontal Care: A Prospective Study

AimTo assess peri‐implant conditions in a cohort of patients previously treated for periodontitis undergoing supportive periodontal care (SPC).Materials and MethodsA prospective observational study was carried out on previously treated periodontitis patients followed for 5 years in SPC. Peri‐implant diagnosis at baseline and the end of the 5‐year period was assessed.ResultsTwo hundred patients were included in the study. A total of 88 implants were present at baseline in 31 of those patients. A total of 55 (62.5%) implants were diagnosed as having healthy peri‐implant tissues, while 22 (25%) were diagnosed with peri‐implant mucositis and 11 (12.5%) with peri‐implantitis. Five‐year data are available for 68 implants in 23 patients. None of these implants was lost during the 5 years follow‐up. An additional 20 implants were placed during the study period, resulting in a total of 88 implants reassessed at the last study follow‐up, with peri‐implant diagnosis almost unchanged compared with baseline. None of the studied patient and implant factors were associated with implant diagnosis in a multilevel model with logistic regression target distribution.ConclusionsA small percentage of implants in a population undergoing SPC were diagnosed with peri‐implantitis, and peri‐implant conditions were maintained almost unchanged during 5 years of SPC.
