Dental autologous transplantation: an integrative literature review

Abstract

Introduction: Autologous dental transplantation is a surgical technique in which there is the transposition of a tooth to a new recipient area within the same patient. It is a viable option for treating dental absenteeism and impactions. The method offers benefits such as the maintenance of vital periodontium, alveolar bone volume, and dental papilla, the possibility of dental movement through orthodontic or physiological forces, and favorable aesthetics. Objective: To promote a literature review on autologous dental transplantation, aiming to report the main indications, benefits, and contraindications of the technique, in addition to describe the surgical protocol and factors influencing success, providing guidance for clinical management. Methodology: For this purpose, the analyzed databases included PUBMED, LILACS, and SCIELO, obtaining Systematic Review and Meta-Analyses articles from the years 2018 to 2023. Results: Autotransplantation presents survival rates between 93% and 100% and success rates between 89.4% and 96.6%, depending on factors related to the patient, the donor tooth, the recipient area, and the surgical technique. Anterior teeth with open apices present better survival and success rates compared to posterior teeth with closed apices, however, there is no conclusive evidence that other factors directly influence the method. Conclusions: Therefore, we can understand that the establishment of preoperative, intraoperative, and postoperative protocols, along with clarification of all factors influencing the technique, should be the focus of studies for Dental Surgeons, bringing significant benefits to these individuals’ health.
