Survival outcomes of third molar autotransplantation according to impaction severity: a retrospective cohort study
Year: 2025
Type: article
Study design: Observational Study
Abstract: Objectives: : Autotransplantation of third molars with complete root formation is a well-established surgical approach for replacing missing teeth, offering biological advantages over conventional prosthetic or implant therapies. The severity of third molar impaction may significantly influence autotransplantation prognosis, yet its clinical significance has not been thoroughly investigated. Materials and Methods: : This retrospective cohort analysis assessed for autotransplantation of the third molar. Patients were categorized based on impaction severity, and Kaplan-Meier survival analysis was conducted to estimate cumulative Survival rates. Differences in survival according to impaction severity were assessed using the log-rank test, with further evaluation of associated factors. Results: =0.002). No significant survival differences were found regarding sex, splinting period, extra-socket time, or healing period. Conclusion: Impaction severity is a critical prognostic factor influencing the prognosis of autotransplantation by using the third molars. Comprehensive preoperative evaluation of donor tooth condition, particularly regarding impaction severity, is essential to maximize transplantation outcomes.
