本研究的目的是对自体移植牙进行回顾性研究，以检查临床标准（如供体牙的类型、移植时的根长、供体萌出阶段等）对移植总体成功率的影响。本研究的材料包括194例患者，其中273颗牙齿移植。自体移植时的平均年龄为18.1岁，标准差为7.5岁。移植手术在两家医院进行。随访时间从15天到11年不等，平均随访时间为3.8年。58/273颗牙齿显示一种或另一种形式的吸收，37/273颗牙齿显示强直，30/273颗牙齿显示髓室大小无重要变化，104/273颗牙齿在移植后显示严重变色，92/213颗牙移植后冷试验结果为阳性，26/273颗牙的牙周袋深度临床上不可接受。进行了临床和放射学评价。移植成功率与供牙类型、牙根类型有关（P < 0.01）.移植时长度（P < 0.0001）和受牙区长度（P = 0.03）。移植成功率与供者萌出期之间存在临界相关性（P = 0.05）。结论：自体牙移植术是一种非常有效的治疗方法，在牙根长度达到预期长度的1/2-3/4时，通过外科手术进行。
The aim of the present study was to perform a retrospective study of autogeneously transplanted teeth in order to examine the influence of clinical criteria such as the type of the donor tooth, the root length at the time of transplantation, donor eruption stage and others on the overall success rate of the transplantation. The material of this study consisted of 194 patients in whom 273 teeth were transplanted. The mean age at the time of autotransplantation was 18.1 years with a standard deviation of 7.5 years. Transplantations were performed in two hospitals. The follow-up period varied from 15 days to 11 years, and the mean follow-up time was 3.8 years.58/273 teeth showed one or other form of resorption, 37/273 teeth showed ankylosis, 30/273 showed no important changes in pulp chamber size, 104/273 showed major discoloration after transplantation, 92/213 teeth showed positive results for cold test after transplantation and 26/273 teeth showed clinically unacceptable pocket depth. Clinical and radiological evaluations were performed. An association was found between successful transplantation and donor tooth type (P < 0.01), root. length at the time of transplantation (P < 0.0001) and recipient tooth site (P = 0.03). There was a borderline association between successful transplantation and donor eruption stage (P = 0.05). In conclusion, autotransplantation of teeth performed with a careful surgical procedure at the stage of 1/2-3/4 of their intended or expected root length can render a very useful service to patients.
