The Impact of Posterior Occlusal Support Recovery by Dental Implant Treatment on the Survival of Remaining Teeth: A Long-Term Retrospective Study.

ABSTRACT: Background: Preservation of posterior occlusal support is critical for maintaining residual dentition in partially edentulous patients. Although implant-supported restorations are widely used, long-term evidence on their role in preventing tooth loss remains limited. Methods: A retrospective cohort study of 225 patients (80 males, 145 females; mean age 53 ± 9 years) who received posterior implant-supported restorations, with a mean follow-up of 21 years. Post-treatment occlusal support was classified using the Eichner classification. Tooth and implant loss were recorded. Associations between residual occlusal support and tooth loss were analyzed using Pearson's chi-square test, with thresholds of ≥1, ≥2, or ≥3 teeth lost. Multivariate logistic regression analyses adjusted for
