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
