- AIM: to determine the prevalence and development of peri-implant mucositis and peri-implantitis and to assess risk factors over time.MATERIALS AND METHODS: The study is a longitudinal case series assessing the occurrence and diagnosis of peri-implant mucositis and peri-implantitis.RESULTS: 218/294 patients who had received dental implants between 1988-1992 were examined between 2000-2002 (exam II; 9-14 years after the first exam). At exam III (20-26 years after exam I, on average 23.3 years), 86 individuals were re-examined. The diagnosis of peri-implant mucositis and peri-implantitis at exam III was 23.8% and 13.7% respectively. Surgical treatment of peri-implantitis after exam II resulted in a bone gain for 2/12 individuals. Individuals with ≥ 3 implants at exam II were at risk for peri-implantitis at exam III (χ2=7.9, p <0.01, LR: 11.6, 95%CI: 1.5, 92.5, p < 0.01). A history of periodontitis (p=0.07), a diagnosis of peri-implant mucositis (p =0.77), or smoking (p=0.86) at exam II, were not predictive of peri-implantitis at exam III.CONCLUSIONS: The diagnosis and occurrence of peri-implantitis and peri-implant mucositis was high. Healthy conditions at implants after 9-14 years were predictive of future implant health. This article is protected by copyright. All rights reserved.
