In 68 patients, 79 tooth germs of the third molar were transplanted. Out of this group, 43 patients with 50 transplantations under-went a follow-up examination. All surgery was performed by one surgeon. Retrospectively, we tried to establish whether the success of postoperative healing depends on the donor and receiver regions. Crossing the jaw border clearly worsens the prognosis for transplantation. Altogether 9 transplantations turned out to be failures, 7 of which had been transplanted from the upper to the lower jaw. The results of this investigation showed incomplete root development in 34%, the necessity of endodontic treatment in 6% and enlarged periodontal pockets in 8%. Ankylosed teeth were found in 10%; we did not see any root resorptions.
在68例患者中，移植了79颗第三磨牙牙胚。在该组患者中，43例患者的50次移植接受了随访检查。所有手术均由一名外科医生进行。回顾性地，我们试图确定术后愈合的成功是否取决于供体和受体区域。跨越颌骨边界明显会使移植预后变差。总共有9次移植失败，其中7次是从上颌移植到下颌。这项研究结果显示，34%的移植牙牙根发育不完全，6%需要进行牙髓治疗，8%出现牙周袋增大。发现10%的移植牙发生了牙根粘连；未观察到任何牙根吸收情况。
