摘要【目的】探讨三维打印牙模型联合富血小板纤维蛋白(PRF)在磨牙自体牙移植中的应用效果。【方法】选取2018年2月至2021年2月在本院行磨牙自体牙移植术的192例患者,按照随机数字表法分为对照组和观察组,每组96例,其中对照组在磨牙自体牙移植中采用三维打印牙模型联合牛骨替代品(Bio-oss),观察组在磨牙自体牙移植中采用三维打印牙模型联合PRF。比较两组移植牙成功率、术后3个月牙周指标[菌斑指数(PLI)、龈沟出血指数(GBI)、临床附着丧失、牙周探诊深度]、咀嚼功能(咬合力与咀嚼效率)、并发症发生率及术后1年患者满意度。【结果】观察组移植牙成功率为94.79%,显著高于对照组的84.38%(P<0.05);观察组牙周指标PLI、GBI、临床附着丧失、牙周探诊深度低于对照组(P<0.05);观察组咬合力、咀嚼效率大于对照组(P<0.05);观察组并发症发生率为3.13%,显著低于对照组的12.50%(P<0.05);观察组患者满意度为95.83%,显著高于对照组的87.50%(P<0.05)。【结论】三维打印牙模型联合PRF应用于磨牙自体牙移植中,可显著提高移植牙成功率,改善牙周指标及咀嚼功能,降低并发症发生率,提升患者满意度。

Abstract：【Objective】To study the effect of three-dimensional printed tooth model combined with platelet rich fibrin (PRF) in molar autologous tooth transplantation.【Methods】One hundred and ninety-two patients who underwent molar autogenous tooth transplantation in our hospital from February 2018 to February 2021 were randomly divided into routine group and study group, with ninety-six cases in each group. The conventional group used three-dimensional printed tooth model combined with bovine bone substitute (Bio-oss), and the study group used three-dimensional printed tooth model combined with PRF. The success rate of transplanted teeth, periodontal indexes [plaque index (PLI), gingival sulcus bleeding index (GBI), clinical attachment loss, periodontal probing depth], masticatory function (bite force and masticatory efficiency) and complications of the two groups were compared, and the patient satisfaction was evaluated one year after operation.【Results】The success rate of transplanted teeth in the study group was 94.79%, which was higher than 84.38% in the routine group (P<0.05). The periodontal indexes PLI, GBI, clinical attachment loss and periodontal probing depth in the study group were lower than those in the routine group (P<0.05). The bite force and masticatory efficiency of the study group were higher than those of the routine group (P<0.05). The incidence of complications in the study group was 3.13%, which was lower than 12.50% in the routine group(P<0.05). The satisfaction of patients in the study group was 95.83% which was higher than 87.50% in the routine group (P<0.05).【Conclusion】The application of three-dimensional printed tooth model combined with PRF in molar autologous tooth transplantation can improve the success rate of transplanted teeth, improve periodontal indexes and masticatory function, reduce the incidence of complications and improve patient satisfaction.
