Tooth autotransplantation is a procedure in which a donor tooth is transplanted within the same patient's jaw to replace a missing tooth. Donor tooth root morphology and periodontal ligament integrity are key factors influencing success. We report a semi-immediate autotransplantation of a maxillary third molar with a 90° divergent root into a site previously affected by a periapical abscess. After the extraction of the compromised tooth (#15) and removal of the interradicular septum, the site was left to heal to allow soft tissue closure and infection resolution. During this period, CBCT imaging and a 3D-printed donor tooth replica (CARP model) were used to plan the procedure, including the intended root amputation. Two weeks later, autotransplantation was performed. The recipient site only required soft tissue and granulation tissue management, with no additional bone preparation, allowing for a minimally traumatic approach. The donor tooth was transplanted with an extraoral time of under 6 min. At the 18-month follow-up, the tooth remained functional, asymptomatic, and radiographically stable. This case highlights the feasibility of delayed autotransplantation following infection and the clinical value of combining imaging with prototyping in surgical planning-particularly when dealing with donor teeth with unfavorable root anatomy.
牙齿自体移植是一种将供体牙齿移植到同一患者颌骨内以替代缺失牙齿的手术。供体牙齿的牙根形态和牙周膜完整性是影响手术成功的关键因素。我们报告了一例将上颌第三磨牙（牙根呈90°分叉）半即刻自体移植到先前受根尖周脓肿影响部位的病例。拔除患牙（#15）并去除根间间隔后，让该部位愈合，以实现软组织闭合和感染消退。在此期间，使用CBCT成像和3D打印的供体牙齿模型（CARP模型）来规划手术，包括预期的牙根截断。两周后，进行了自体移植。受体部位仅需进行软组织和肉芽组织处理，无需额外的骨预备，从而实现了微创方法。供体牙齿的口外操作时间不到6分钟。在18个月的随访中，该牙齿保持功能正常、无症状且影像学稳定。该病例突出了感染后延迟自体移植的可行性以及在手术规划中将影像学与模型制作相结合的临床价值——尤其是在处理牙根解剖结构不利的供体牙齿时。
