This paper is a report on 25 autotransplantations of third molars with complete root formations. The study consists of 23 patients in whom 25 third molars were transplanted. The mean age was 29.6 years (range 20-54). In nine cases third molars were directly transplanted into the new socket. In 11 cases the sockets were widened and made deeper with a bur. In five cases the recipient beds were made by splitting osteotomy of the alveolar region. The transplanted third molars were stabilized with silk sutures, resin, wire splint or circumferential wiring for 1-6 weeks. Two-three weeks after transplantation, the root canals were treated and filled. After operation, the marginal and the periapical conditions were examined clinically and radiographically. The transplanted teeth clinically appeared to become firmer with the passage of time. Progressive root resorption was not found and good results were obtained. This study shows that autotransplantation of third molars with complete root formation produces an acceptable result using the procedures outlined.
本文是关于25颗牙根完全形成的第三磨牙自体移植的报告。该研究包括23例患者，共移植了25颗第三磨牙。平均年龄为29.6岁（范围20 - 54岁）。9例中第三磨牙直接移植到新牙槽窝。11例中用牙钻将牙槽窝扩大并加深。5例中通过牙槽嵴劈开截骨术制备受植床。移植的第三磨牙用丝线缝合、树脂、钢丝夹板或环绕结扎固定1 - 6周。移植后2 - 3周，进行根管治疗并充填。术后，通过临床和影像学检查边缘及根尖情况。随着时间推移，移植牙在临床上似乎变得更稳固。未发现进行性牙根吸收，取得了良好效果。本研究表明，采用所述方法对牙根完全形成的第三磨牙进行自体移植可产生可接受的结果。
