The purpose of this study was to investigate the prognosis of 50 consecutively autotransplanted teeth to the maxillary incisor region. Thirty-five were transplanted in cases of traumatic injuries, eleven in cases of agenesis and four in cases with impaction of maxillary canines. The average follow-up time was 7 years and 6 months (range 4-17 years). The transplants were examined clinically in respect of tooth vitality and radiographically in respect of root canal obliteration, periradicular changes, root formation, and root length. The results show a success rate of 82 per cent. It is concluded that the procedure of tooth transplantation has the advantage of maintaining or restoring alveolar bone volume and gives the opportunity to replace a missing tooth without involvement of neighbouring teeth as prosthetic abutments.
本研究的目的是调查连续50颗自体移植到上颌切牙区牙齿的预后情况。其中35颗因外伤而移植，11颗因牙胚缺失而移植，4颗因上颌尖牙阻生而移植。平均随访时间为7年6个月（范围4 - 17年）。对移植牙进行临床检查以评估牙齿活力，并进行影像学检查以评估根管闭锁、根尖周变化、牙根形成和牙根长度。结果显示成功率为82%。得出的结论是，牙齿移植手术具有维持或恢复牙槽骨体积的优势，并且有机会在不涉及邻牙作为修复基牙的情况下替换缺失牙。
