摘要： 通过模型反求的方法得到实验模型;结合可靠性理论进行大量采样试验,对模型进行有限元数值模拟和分析,以此研究种植术与分根术联合治疗术后牙体的可靠性,分析影响手术远期治疗成功率的因素,并得出在可靠度达到80%时牙体的极限载荷。通过分析计算得知牙体受力情况以及骨质性能是影响种植术与分根术联合治疗远期成功率的最关键因素,且经过种植术与分根术联合治疗后的牙体完全可以胜任日常咀嚼及咬合任务,但应尽量避免斜向受力及咬合过硬食物。

Abstract: Obtaining experimental models by the method of model reverse.In order to Study on reliability of dental implantation and split-root technique joint repaired postoperative dental, analysis of factors which affect the success rate of treatment, and calculating the limit load when reliability reached 80%, combining with the reliability theory to obtain the desired number of samples test and performing finite element simulation and analysis to the model. Numerical simulations show that the stress direction and bone properties are the most important factors to influence the long-term success rate of treatment,and after treatment the tooth can be competent for the daily chewing and biting tasks, but should try to avoid oblique stress and bite hard food.

Key words: split-root technique, finite element, reliability, realisitic model, implantation
