The present invention relates to method for simulating mandibular movements, device for the same and recording medium for recording the same. With the method for simulating mandible movements according to the present invention, it is possible to perform the simulation directly on the medical image of the patient and thus simulate the mandibular movements more closely to the actual situation. Therefore, the inaccurate mechanical approximation of the mandibular movement with the articulator according to the conventional art is overcome. In addition, according to the present invention, it is possible to simulate mandibular movements customized to the various states of the patient and specific clinical cases.
