摘要： 本文报告1例下颌支内阻生第二磨牙自体移植病例。利用数字化外科、微创拔牙等技术将下颌支内阻生第二磨牙取出后即刻自体移植至原第二磨牙区，同期将自体骨粉填入移植牙颊侧和远中骨缺损区，弹性固定移植牙。术后咬合关系良好，即刻动度I度，骨缺损得到填充修复。术后6个月行根管治疗，1年后经临床和影像学检查移植牙愈合良好。下颌支内阻生磨牙自体移植至缺失磨牙区可以成为自体牙移植术的适应证。

Abstract: This paper reported a case with autotransplantation of a mandibular second molar impacted in mandibular ramus to its normal position. By using digital surgery and minimally invasive tooth extraction, an impacted mandibular second molar was immediately autotransplanted from mandibular ramus to its normal position. After the buccal and distal bone defect was filled by autologous bone, the transplanted tooth was elastically fixed. Postoperative occlusal relationship was good, the immediate mobility was I degree, and the bone defect was repaired. Root canal therapy was completed 6 months later. Clinical and radiographic examination showed the transplanted tooth healed well 1 year later. Transplantation of impacted molar from mandibular ramus to its normal position can be an option for autogenous teeth transplantation.

Key words: Autotransplantation, Impacted second molar, Digital surgery
