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, 92/273 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.
本研究的目的是对自体移植牙进行回顾性研究，以检验诸如供体牙类型、移植时的牙根长度、供体萌出阶段等临床标准对移植总体成功率的影响。本研究的材料包括194例患者，共移植了273颗牙齿。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。随访期从15天到11年不等，平均随访时间为3.8年。273颗牙齿中有58颗出现了一种或另一种形式的吸收，37颗出现了牙根粘连，30颗牙髓腔大小无明显变化，104颗在移植后出现了严重变色，92颗在移植后冷测试结果为阳性，26颗临床袋深度不可接受。进行了临床和影像学评估。发现移植成功与供体牙类型（P<0.01）、移植时的牙根长度（P<0.0001）和受体牙部位（P=0.03）之间存在关联。移植成功与供体萌出阶段之间存在临界关联（P=0.05）。总之，在预期或期望牙根长度的1/2 - 3/4阶段进行仔细的外科手术自体移植牙，可为患者提供非常有用的治疗。
