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

Abstract

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.
