In this case report, the authors aim to review the standard protocols for endodontic treatment of autotransplanted molars and report on the 5-year follow-up of a clinical transplantation case.
The authors transplanted a mandibular third molar into the position of the adjacent second molar. The authors performed extraoral apicoectomy and retrograde restoration after atraumatic extraction of the donor tooth and before transplantation. The authors did not perform conventional orthograde root canal treatment after transplantation. The patient was followed up 5 years after the autotransplantation. Results of follow-up radiography showed a regular root surface without evidence of periapical lesions or root resorption.
If appropriate sterility of the working field is maintained during surgery and a tight apical seal is achieved during the extraoral treatment, orthograde endodontic treatment should be delayed or avoided.
在本病例报告中，作者旨在回顾自体移植磨牙的根管治疗标准方案，并报告一例临床移植病例的 5 年随访结果。
作者将下颌第三磨牙移植到相邻第二磨牙的位置。作者在微创拔牙并移植前对供体牙进行了体外根尖切除术和逆行修复。作者在移植后未进行常规的顺行根管治疗。患者在自体移植后 5 年进行了随访。随访 X 光片的结果显示，根面规则，无根尖病变或根吸收的证据。
如果手术过程中保持工作区域的适当无菌性，并在体外治疗时达到紧密的根尖封闭，那么应该延迟或避免进行顺行根管治疗。
