This case report describes the technique and 24-month follow-up of autotransplantation of a well-shaped, healthy supernumerary maxillary central incisor as a replacement for a fused maxillary incisor. Because the alignment of the teeth neighboring the fused incisor was not suitable as an abutment for post-transplantation splinting, a custom palatal splint that took anchorage from permanent first molars was fabricated. Following extraction of both teeth, the supernumerary incisor was immediately autotransplanted into the extraction site of the fused incisor. The autotransplanted tooth was secured to the custom splint with acid-etch composite, and the splint was removed 2 weeks later. Closure of the apex was observed at 18 months. Both the esthetics and function were restored to an ideal level in the absence of postoperative complications, as evidenced by 24-month clinical and radiographic findings.
本病例报告描述了自体移植形态良好、健康的上颌多生中切牙以替代融合上颌切牙的技术及24个月随访情况。由于融合切牙相邻牙齿的排列不适合作为移植后夹板固定的基牙，制作了一种从恒第一磨牙获取固位的定制腭侧夹板。拔除两颗牙齿后，将多生切牙立即自体移植到融合切牙的拔牙部位。用酸蚀复合树脂将自体移植牙固定在定制夹板上，2周后拆除夹板。18个月时观察到根尖闭合。24个月的临床和影像学检查结果表明，在无术后并发症的情况下，美观和功能均恢复到理想水平。
