Autogenous tooth transplantation (ATT) can be considered when there is a hopeless molar tooth and suitable donor present. This report presents an unconventional case of successful ATT of a third molar replacing the adjacent fractured second molar in a 33 year old woman. This wisdom tooth had completely developed roots. Root-end filling with Calcium Enriched Mixture (CEM) cement was performed in the third molar. The second molar was extracted non-traumatically without any bone removal; the wisdom tooth was immediately transplanted into the recipient socket. No endodontic treatment was carried out either during or after the ATT. At six-month and 2-year clinical examination the patient was asymptomatic; the transplanted tooth was still functional, with no evidence of marginal periodontal pathosis. At the same follow ups, radiographic evaluation illustrated bone regeneration, normal PDL, and absence of external root resorption. Transplantation of mature third molar seems to be a promising method for replacing a lost permanent molar tooth and restoring aesthetics and function.
当存在无法保留的磨牙且有合适的供体牙时，可考虑自体牙移植（ATT）。本报告介绍了一例非常规的成功自体牙移植病例，在一名33岁女性中，第三磨牙替代了相邻的折断的第二磨牙。这颗智齿的牙根已完全发育。对第三磨牙进行了富钙混合物（CEM）水泥根尖充填。非创伤性拔除第二磨牙，未去除任何骨质；智齿立即植入受植牙槽窝。自体牙移植过程中及术后均未进行牙髓治疗。在6个月和2年的临床检查中，患者无症状；移植牙仍有功能，无边缘性牙周病变迹象。在相同的随访中，影像学评估显示有骨再生、牙周膜正常且无牙根外吸收。成熟第三磨牙的移植似乎是一种有前景的方法，可用于替代缺失的恒牙并恢复美观和功能。
