Cross-sectional analysis reveals socioeconomic disparities in oral rehabilitation access for older adults.

To estimate the prevalence of dental implants and assess socioeconomic inequalities in access among older Brazilian adults.
Cross-sectional analysis using data from the 2023 Brazilian Oral Health Survey.
Descriptive analyses, Rao-Scott tests, and multivariable logistic regression were conducted.
Inequalities were assessed via slope and relative indices of inequality for income and education.
21.1% of older adults reported having at least one dental implant, with prevalence higher in those earning ≥5 minimum wages (54.0%).
Absence of implants was linked to lower income (≤1 minimum wage; OR=4.06, 95% CI: 2.36-6.99) and infrequent dental visits (>3 years; OR=2.56).
Socioeconomic position, particularly income, was the strongest determinant of access to implant-supported prostheses.

Drumond et al. (2026) studied this question.
