Patients with rapidly progressing periodontitis may require extractions of teeth with poor periodontal prognosis. Although replacement with a dental implant is a popular choice, teeth autotransplantation remains a viable option. Herein, we report a case of a 23-year-old patient with rapidly progressing periodontitis resulting in severe clinical attachment loss on the left maxillary first molar, which required extraction. The tooth was replaced by tooth autotransplantation of the unerupted immature left mandibular third molar, which was delivered carefully without compromising the periodontal ligament. Cone beam computed tomography and three-dimensional printing of the third molar donor tooth significantly aided the tooth autotransplantation procedure. Recovery was uneventful. At the 1-year follow-up, healthy periodontal parameters and radiographic features were noted, and the autotransplanted tooth remained vital. This case showed that tooth autotransplantation is a viable option for replacing tooth loss due to rapidly progressing periodontitis.
患有快速进展性牙周炎的患者可能需要拔除牙周预后不良的牙齿。尽管种植牙是一种受欢迎的选择，但牙移植仍然是一种可行的选择。本文报告了 1 例 23 岁快速进展性牙周炎患者，左上第一磨牙出现严重的临床附着丧失，需要拔牙。该牙被未萌出的左下第三磨牙牙移植所替代，在不损害牙周膜的情况下小心地移植。第三磨牙供体的锥形束 CT 和三维打印显著辅助了牙移植手术。恢复顺利。在 1 年的随访中，观察到牙周参数和影像学特征健康，移植牙保持活力。该病例表明，牙移植是治疗快速进展性牙周炎导致牙齿缺失的一种可行选择。
