In order to simulate the mechanical effect caused by the surgical operation, three-dimensional finite element model of the human mandible was proposed. Using the model, we examined the mechanical response during biting after the surgical operation. The computational results showed that the model serves useful knowledge in surgical operations. 1 INTRODUCTION The ram us split osteotomy is a useful technique for a patient who has mandibular skeletal deformity. The surgical technique is a process which splits the bot
