Abstract

To identify factors associated with the use of dental implants in Brazilian adults and older adults.
This cross-sectional analytical study utilized population-based data from the 2023 National Oral Health Survey. The sample comprised adults (35-44 years) and older adults (65-74 years). Two dichotomous outcomes were modeled: self-reported implant use (yes/no) and clinically observed presence of implants (none/one or more). Adjusted odds ratios (ORs) were estimated using multiple logistic regression for complex samples, with demographic and socioeconomic factors, type of dental service used, and number of missing teeth as independent variables.
The prevalence of dental implants ranged from approximately one-tenth to one-fifth of the sample, depending on the method of identification. In the adjusted analysis for self-reported use, older adults, individuals with higher income, those who used private dental services, and those who sought care for treatment or rehabilitation had significantly higher odds of reporting implant use. Conversely, when analyzing clinically observed implants, only the number of permanent teeth lost showed a significant association.
The use of dental implants in the Brazilian population reflects both the accessibility of dental services and the clinical need for rehabilitation. Using different identification methods provides a more comprehensive understanding of the distribution of implants across the country. These findings can allow the refinement of clinical and organizational criteria for the provision of implant-supported oral rehabilitation within the public system, thereby promoting greater equity and sustainability.
