Objectives: Evaluation of the prevalence rates of periimplant mucositis and periimplantitis in partially edentulous patients in a private dental practice.
Material and methods: The data of 89 patients were collected (52 female, 37 male, age at time of implant placement: 51.8±10.3 years). All patients had been treated with dental implants of the same type and fixed superstructures between January 1999 and June 2006 (observational period: 68.2±24.8 months).
Results: The patient-related prevalence rate of periimplant mucositis (probing depth ≥4 mm and bleeding on probing [BOP]) was over all 44.9%. The respective rates in non-smokers without periodontal history were 30.4% and in smokers with periodontal history 80%. The multiple logistic regression analysis identified a significant association of mucositis with the independent variable “smoker” (odds ratio [OR] 3.77; P=0.023). The patient-related prevalence rate of periimplantitis (probing depth ≥5 mm, BOP/pus, radiographic bone loss) was 11.2% (smokers with periodontal history: 53.3%, non-smokers: 2.8%). No periimplant disease was diagnosed in non-smoking patients without periodontal history and with a good compliance after treatment. Statistical analysis identified a significant association of periimplantitis with “smoker” (OR: 31.58; P<0.001) and “compliance” (OR: 0.09; P=0.011). Periodontal history in general showed no significant association with periimplantitis.
Conclusions: Smoking and compliance are important risk factors for periimplant inflammations in partially edentulous patients.
