Autotransplantation is considered a standard procedure with a poorer prognosis for mature than for immature teeth. In this case report, the root tip of an almost fully developed tooth was resected during autotransplantation to fit into a deficient recipient site. As a positive side effect, the apical foramen was enlarged, with potential improvement of the probability of revascularization. Clinical and radiologic follow-up examinations up to 18 months indicated revascularization and uneventful periodontal regeneration and thus successful autotransplantation. This case supports the hypothesis that intraoperative apicoectomy can improve the prognosis for revascularization of mature autotransplanted teeth. Further prospective controlled clinical studies are needed to confirm this innovative surgical approach.
自体移植被认为是一种标准程序,对于成熟牙比不成熟牙的预后较差。在本病例报告中,在自体移植过程中切除了几乎完全发育的牙齿的根尖,以适应缺陷的受植部位。作为一个积极的副作用,根尖孔被扩大,可能增加了再血管化的概率。临床和放射学随访检查长达 18 个月,显示了再血管化和牙周组织再生,因此自体移植成功。本病例支持术中根尖切除术可以改善成熟自体移植牙再血管化预后的假设。需要进一步的前瞻性对照临床研究来证实这种创新的手术方法。
