Autogenous tooth transplantation (ATT) is a simple and reasonable choice for replacing the missing teeth when a proper donor tooth is available. This report presents a case of successful ATT of a maxillary right third molar for replacement of mandibular right second molar with a concomitant endodontic-periodontal disease. The mandibular second molar was believed to be hopeless due to a severe damage to coronal tooth structure, inappropriate root canal treatment and apical radiolucency. After extraction of mandibular second molar and maxillary third molar (the donor), the tooth was re-implanted into the extracted socket of second molar site. Root canal therapy was then performed. After 3 years, clinical and radiographic examinations revealed satisfying results, with no signs and symptoms. The patient is asymptomatic and the transplanted tooth is still functional with no signs of marginal periodontal pathosis. Radiographies showed bone regeneration in the site of previous extensive periapical lesion, normal periodontal ligament with no signs of root resorption.
自体牙移植（ATT）是在有合适供体牙时，用于替代缺失牙的一种简单且合理的选择。本报告介绍了一例成功的上颌右侧第三磨牙自体牙移植病例，该牙用于替代伴有牙髓牙周疾病的下颌右侧第二磨牙。由于冠部牙体结构严重受损、根管治疗不当以及根尖区透射影，下颌第二磨牙被认为已无法保留。拔除下颌第二磨牙和上颌第三磨牙（供体牙）后，将该牙重新植入第二磨牙拔除后的牙槽窝内。随后进行了根管治疗。3年后，临床和影像学检查显示结果令人满意，无任何体征和症状。患者无症状，移植牙仍能正常行使功能，无边缘性牙周病变的迹象。影像学检查显示，先前广泛根尖病变部位有骨再生，牙周膜正常，无牙根吸收迹象。
