[Three dimensional FEM analysis of stress distribution around dental implants to estimate the influence of the length]
The effect of the length of implants on stress distribution is one of the important subjects in implantology.In this study,Three dimensional finite element methods model was constructed by dental CT images,The purpose of this study was to evaluate the stress distribution in bone adjacent to an implant after application of loading in horizontal,oblique and vertical direction.It was show that the highest stress occured at the cervical bone margin adjacent to the implant only 10% decrease in inverse two times increase in implant length,and correlated little to the implant length,therefore,it was unnecessary to emphasize the length of the implants in clinic.
