Risk Indicators of Peri-Implant Diseases in Public and Private Clinics: A Multicenter Study

Background and Objective. The success of implant treatment may be compromised by peri-implant diseases. It would be advantageous to identify the factors that could make implants more susceptible to these conditions in order to prevent and manage peri-implant diseases. This study aimed to determine the prevalence of peri-implantitis, peri-implant mucositis, and their potential risk indicators. Methods. Patients examined during postloading maintenance visits were included in this study. The presence of peri-implant mucositis, peri-implantitis and several patient- and implant-related independent variables was recorded. Statistical analysis was performed using the logistic regression analysis. The odds ratios (OR) of the potential association between each variable and the occurrence of peri-implant diseases were evaluated. Results. Among the 114 participants with 403 implants, peri-implantitis was found in at least one implant of nine individuals (7.89%), and a total of 13 implants were affected by peri-implantitis (3.22%). The univariate regression analysis revealed a statistically significant association between arch (OR = 4.81; 95% CI = 1.27-31.36) and soft tissue thickness (OR = 4.07; 95% CI = 1.33-13.73) with the occurrence of peri-implantitis. The multivariate analysis confirmed the significant impact of soft tissue thickness (OR = 3.60; 95% CI = 1.16-12.24). Conclusion. The occurrence of peri-implant diseases can be influenced by various factors. However, in order to accurately identify risk indicators, it is necessary to conduct long-term prospective studies.
