摘要

回顾性研究了27位口腔外科医生在25年间进行的291例自体人牙移植,分析了手术时的临床和放射学因素,并参考了它们与预后的相关性。采用单因素寿命表分析和多因素Cox回归分析确定移植牙缺失的预后相关因素。在Cox回归分析分析的11个因素中,以下因素似乎与移植物丢失或保留的预后相关:移植物的发育阶段、患者的年龄、供牙类型、供牙的异位、移植物的口外储存和口腔外科医生。在本研究中,预防使用抗生素和固定时间等因素似乎对移植物的预后没有显著影响。使用相关参数,可以为个体患者创建预后预测。给出了一个具有一组有利参数的案例。

Autotransplantation of human teeth

In a retrospective study of a sample of 291 autotransplantations of human teeth carried out by 27 oral surgeons over a period of 25 years, the clinically and radiologically available factors at the time of surgery were analysed with reference to their prognostic relevance. Prog-nostically relevant factors related to loss of the transplanted teeth were determined by both univariate life-table analysis and multivariate Cox regression analysis. Of the 11 factors analysed in the Cox regression analysis, the following seemed to be prognostically relevant to loss or retention of the graft: developmental stage of the graft, age of the patient, donor tooth type, ectopia of the donor tooth, extraoral storage of the graft, and oral surgeon. In the present material, the prognosis of the grafts did not seem to be significantly influenced by such factors as prophylactic administration of antibiotics and fixation time. Using relevant parameters, it is possible to create a prognosis forecast for the individual patient. A case with a favourable set of parameters is shown.
