Abstract: Aiming at the high operational requirements of mandibular fracture surgery, the virtual surgery system for training and preoperative simulations using Unity3D and HTC VIVE is developed. The virtual surgery system is divided into three-dimensional model module, illumination system module, interactive system module and operating room instantaneous movement module. The scene, interaction and operation procedure of mandibular fractures are simulated. The results show that the virtual operation system has a good sense of reality, immersion and interactivity, can effectively guide the operator to complete the surgical process, and achieve the purpose of surgical training and simulating.
