Autotransplantation is a viable option for treating missing teeth when a donor tooth is available. This retrospective study reports the success rate for the autotransplantation of 19 molars with complete root formation.
The study enrolled 19 patients (11 men and 8 women) in whom 19 molars were transplanted. The mean age was 38.5 years (range, 19-67). The transplanted third molars were stabilized with a silk suture or wire splint for 2 to 3 weeks. Root canal treatment of the transplanted teeth was performed before surgery in six patients and 1 to 2 weeks after transplantation in 13 patients. Postoperatively, the marginal and periapical conditions were examined clinically and radiographically.
In 16 of the 19 cases, the outcome met the success criteria, for an 84% success rate.
In autogenous tooth transplantation, even if the donor tooth has complete root formation, a high success rate can be achieved if the cases are selected and treated properly.
当有可供利用的供体牙时，自体移植是治疗缺失牙的可行选择。本回顾性研究报告了 19 颗完全形成根的磨牙自体移植的成功率。
本研究纳入了 19 名患者（11 名男性和 8 名女性），共移植了 19 颗磨牙。平均年龄为 38.5 岁（范围 19-67 岁）。移植的第三磨牙用丝线或金属丝夹板固定 2-3 周。6 名患者在手术前进行了根管治疗，13 名患者在移植后 1-2 周进行了根管治疗。术后，临床和影像学检查了边缘和根尖状况。
19 例中有 16 例符合成功标准，成功率为 84%。
在自体牙移植中，即使供体牙完全形成根，只要选择和治疗得当，仍可获得较高的成功率。
