Recently, the number of middle–aged and elderly orthognathic surgery patients with un-healthy oral conditions has been increasing. Although an interdisciplinary approach in-volving orthodontist, oral surgeon and prosthodontist is required in orthognathic surgery of these patients, deciding the jaw position after orthognathic surgery is difficult due to unhealthy oral conditions such as edentulous jaw and tooth loss. In the recently study, preoperative simulation methods for orthognathic surgery have been developed through the use of virtual reality computed technology. A male first examined at the age of 36 years and 7 months was diagnosed as having mandibular protrusion with multiple tooth loss and mandibular deviation. The patient was treatedinterdisciplinary by a team of specialists in surgical orthodontic, dental prosthetic and periodontal treatment. Using the interdisciplin-ary approach and haptic device with virtual tactile perception showed satisfactory results loss treated with orthognathic surgery
