摘要

牙齿自体移植是将一颗供体牙齿移植到同一患者的颌骨内,以替代缺失的牙齿。供牙根形态和牙周韧带完整性是影响手术成功的关键因素。我们报告一个半即时自体移植的上颌第三磨牙与90°发散根到一个地方以前受影响的根尖周脓肿。在拔出受损牙齿(#15)并去除根间间隔后,留下该部位愈合,以便软组织关闭和感染解决。在此期间,使用CBCT成像和3d打印供牙复制品(CARP模型)来计划手术,包括预定的牙根截肢。两周后进行自体移植。受体部位只需要软组织和肉芽组织处理,不需要额外的骨准备,允许最小创伤的方法。供牙移植时间不超过6分钟。在18个月的随访中,牙齿保持功能,无症状,影像学稳定。本病例强调了感染后延迟自体移植的可行性,以及在手术计划中结合影像学和原型设计的临床价值,特别是在处理牙根解剖不良的供牙时。

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.
