The aim of autotransplantation of teeth (ATT) is to replace a lost tooth with a functional tooth within the same patient. Although it has recently become more of a recognized and viable treatment approach in dentistry, the long-term outcomes are still not well-documented. The principal author (MT) has performed more than 1000 ATTs for reasons such as treating missing teeth, deep caries, poor endodontic results, and periodontitis over the past 30 years in private practice. During the course of private practice, 2 separate analyses were performed on a total of 319 cases with follow-up ranging from 2 to 26 years. The results showed a tendency toward higher success rates in younger patients; the success rate was highest in ATTs performed on immature teeth (about 95%), about 90% in patients younger than 30 years of age and approximately 80% in patients older than 30. The failures were most often caused by replacement resorption (ie, ankylosis-related resorption). The purpose of this case series was to show successful long-term outcomes of ATT as well as to provide clinical insights and describe tendencies noted over the course of 30 years of performing ATTs.
自体牙移植（ATT）的目的是在同一患者体内用功能性牙齿替代缺失的牙齿。尽管最近在牙科领域，它已成为一种更为公认和可行的治疗方法，但长期结果仍未得到充分记录。主要作者（MT）在过去 30 年的私人执业中，出于治疗缺失牙、深龋、不良牙髓治疗结果和牙周炎等原因，已经进行了超过 1000 例的 ATT。在私人执业过程中，对总共 319 例患者进行了 2 次单独分析，随访时间为 2 至 26 年。结果表明，年轻患者的成功率有升高趋势；未成熟牙（约 95%）的 ATT 成功率最高，30 岁以下患者成功率约为 90%，30 岁以上患者成功率约为 80%。失败的主要原因是替代性吸收（即与牙骨质粘连相关的吸收）。本病例系列旨在展示 ATT 的成功长期结果，并提供临床见解，描述 30 年 ATT 操作过程中注意到的趋势。
