Young, growing individuals with one or more upper incisors missing due to trauma, agenesis or extraction of abnormal teeth can be treated with autotransplantation to restore aesthetics and function and to preserve the volume of the alveolar process. Studies have been performed to evaluate the prognosis, indicating a good prognosis, especially if an immature transplant is available, developed to 3/4 of the full root length. The purpose of this study was to analyse the result of all autotransplantation of teeth performed to the upper incisor region between 1979 and 1990 at the Department of Oral Surgery, Eastmaninstitutet, Stockholm, Sweden. The material consists of 23 immature and 22 mature teeth in 40 patients with a mean age of 12 years. They were systematically followed up clinically and roentgenologically for up to four years after surgery. 22 of the 23 immature (96%) and 18 of the 22 mature teeth (82%) were observed to be without serious complications. The complications occurred, with one exception, within the first year of observation. The conclusion drawn from this study is that autotransplantation to the upper incisor region can be performed with a good prognosis, both for mature and immature teeth.
由于外伤、发育不全或拔除异常牙齿而导致一颗或多颗上颌切牙缺失的年轻生长个体，可以通过自体牙移植来治疗，以恢复美观和功能，并保留牙槽突的体积。已经开展了多项研究来评估预后情况，结果表明预后良好，尤其是当有发育至牙根全长3/4的未成熟移植牙可用时。本研究的目的是分析1979年至1990年期间在瑞典斯德哥尔摩伊斯特曼研究所口腔外科对40名平均年龄为12岁的患者在上颌切牙区进行的所有牙齿自体移植的结果。该材料包括40名患者的23颗未成熟牙齿和22颗成熟牙齿。术后对他们进行了长达四年的系统临床和影像学随访。23颗未成熟牙齿中的22颗（96%）以及22颗成熟牙齿中的18颗（82%）未观察到严重并发症。除一例例外，并发症均发生在观察的第一年内。本研究得出的结论是，上颌切牙区的自体牙移植，无论是成熟牙齿还是未成熟牙齿，预后都良好。
