ABSTRACT

Objectives: This study aimed to compare the characteristics of partial dentures supported by dental implants and to analyze related factors to provide data. This data can serve as a basis for oral health-related insurance policies for the elderly. Methods: Using data from the 8th National Health and Nutrition Survey, we analyzed the data from 4,304 individuals aged ≥65 years. Based on the Andersen behavioral model, we set the antecedent, possible, and necessary factors as independent variables. We performed logistic regression analysis with dental implants and partial dentures as dependent variables. Results: Implant possession was affected by male sex, younger age, higher education, income levels, and healthy lifestyle habits. In contrast, partial denture possession was affected by older age, lower education and income levels, unhealthy lifestyle habits, and chewing discomfort. Conclusions: The factors affecting the possession rates of dental implants and partial dentures demonstrated opposite trends. Implants were more affected by health behaviors, whereas partial dentures were more affected by socioeconomic factors. Therefore, a policy to expand the dental coverage must establish a differentiated strategy that considers the characteristics of each type of prosthesis.
