Three-dimensional Finite Element Displacement and Stress Analysis of Abutment Teeth Retained by Conical Telescope

LU Xuan, MAN Yi, LIN Yinghe, et al. West China School of Stomatology, Sichuan University, Chengdu 610041  
Objective To study stress distribution and displacement of abutment teeth of removable partial denture which is retained by using conical telescope. Methods An ideal three dimensional finite element model was constructed by using SCT image reconstruction technique, self-programming and ANSYS software. The static loads were applied. The stress distribution and displacement characteristics of different abutment teeth were compared and analyzed. Results Generally, the different abutment teeth produce almost the same stress and displacement at the site of abutment teeth. Conclusion Under the occlusal force, the different abutment teeth in the conical telescope sink together and endure the occlusal force.
