The goal of tooth autotransplantation is to restore a missing tooth by using a functional tooth from the same patient. Although this procedure is gaining more recognition as a viable treatment option in dentistry, it is important to monitor and report long-term results. This case report presents the long-term follow-up of a fused maxillary central incisor that was extracted and replaced with a supernumerary tooth. Although the donor tooth displayed favorable characteristics, including an intact periodontal ligament and minimal extraoral time, which contributed to the success of the transplantation, it also presented certain disadvantages, such as having a fully developed root apex. Over a 9-year follow-up period, no clinical symptoms indicative of functional failure were observed. However, external cervical root resorption, first detected at the 6-year follow-up, progressed by the ninth year. Despite the lack of clinical symptoms, radiographic findings suggested that the root resorption was a significant concern. This case underscores the potential for long-term success of autotransplanted teeth, even in complex scenarios involving fused teeth. However, it also highlights the importance of thorough, long-term monitoring to detect complications such as root resorption. The findings suggest that, while autotransplantation can offer favorable outcomes, careful management and periodic evaluations are essential to ensure the longevity of the transplanted tooth.
牙齿自体移植的目的是通过使用同一患者的一颗功能牙来修复缺失牙。尽管该手术作为牙科领域一种可行的治疗选择正获得越来越多的认可，但监测和报告长期结果很重要。本病例报告展示了一颗融合上颌中切牙拔除后用一颗多生牙替代的长期随访情况。尽管供体牙具有有利特征，包括完整的牙周膜和最短的口外时间，这有助于移植成功，但它也存在某些缺点，比如根尖已完全发育。在9年的随访期内，未观察到提示功能失败的临床症状。然而，在6年随访时首次发现的颈缘外牙根吸收在第9年时有所进展。尽管没有临床症状，但影像学检查结果表明牙根吸收是一个重大问题。本病例强调了即使在涉及融合牙的复杂情况下，自体移植牙也有长期成功的可能性。然而，它也凸显了进行全面、长期监测以发现诸如牙根吸收等并发症的重要性。研究结果表明，虽然自体移植可以带来良好的效果，但仔细管理和定期评估对于确保移植牙的长期留存至关重要。
