To evaluate the stress distribution on bone adjacent to an implant under the vertical load, oblique load and horizontal load. Obtained three dimensional radiographic data of the jaw by dental CT scan. Based on the scanning sections, the three-dimensional finite element analysis mandible model was established. Loading vertical, oblique and horizontal forces on the implant, calculated the maximum stress, minimum stress and von mises stress. The peak stress occurred at the cervical bone margin adjacent to the implants;the stress concentration under the vertical loading is easily concentrated than that of vertical loading. In the clinical designation,not only the force of bite but also the direction of the force should both be emphasised.
