CONTRIBUTING FACTORS TO THE SUCCESS OF AUTOGENOUS TOOTH TRANSPLANTATION

Abstract

Autogenous tooth transplantation (ATT) is a procedure that has been documented for decades, yet it remains underutilized in Brazilian dentistry. Its limited use stems from the historical stigma that only children and adolescents achieved good results, leading many professionals to disregard its application in adults. However, scientific and technological advancements demonstrate that, when properly planned, ATT can offer functional, aesthetic, and biological restoration without the use of artificial materials. The success of the treatment depends on multidisciplinary factors, involving systemic, periodontal, endodontic, surgical, and orthodontic analyses. The objective of this study was to identify, through a literature review, the main factors influencing the prognosis of autogenous transplantation, understanding the importance of pre-operative planning, surgical execution, and post-operative follow-up. It also sought to understand how different areas of dentistry correlate to ensure better outcomes. The methodology consisted of a bibliographic search in the PubMed database, including articles, systematic reviews, and case reports without exclusion criteria, prioritizing publications in English. Seventeen studies from various countries were analyzed, covering surgical techniques, pulp vitality, digital planning, the use of 3D models, and clinical risk factors. It is concluded that autogenous tooth transplantation is an effective and viable alternative for oral rehabilitation, especially in cases where implants are not indicated, such as in young patients or those with systemic contraindications. The success rate, reported in studies with large samples, reaches approximately 91% when proper planning is in place. The use of technologies, such as 3D printing and tomography, associated with a multidisciplinary approach, significantly increases the predictability of the procedure. Despite the promising results, more clinical studies are needed to standardize techniques and deepen the understanding of factors influencing long-term success.
