Abstract The direction of dental implant is one of the important factors of longterm success of dental implants. This paper presents a method for the initial orientation design of dental implants based on the occlusal center recovery mechanical model. The occlusal center recovery mechanical model was established with the data from the CT of the patients, the data of the dental cast models and the measured data of occlusal force. The established occlusal center recovery mechanical model was used in the quantitatively studies and to accomplish the initial orientation design. This method can provide the mechanical basis and references for the orientation design of implants, and further provide a new idea for the improvement of surgical guide of the existing implant system. This modeling and design method was applied and observed in six subjects. The results showed both the angle of mesiodistal inclination and the angle of buccolingual inclination are less than 10～15 degrees. Therefore, this method is feasible and effective.
