Abstract :
In order to realize real-time navigation in orthognathic surgery, i.e. to realize real-time tracking the pose (position and rotation) of the patient and the instruments, we developed a 3D osteotomy simulation and real-time navigation system (3D OsteoSim&Nav) for the first time in China. After the preoperative 3D simulation, system matches the markers on 3D model to the markers in surgical patient´s site to complete the registration. Then the system real-time tracks the pose of the surgical instruments and patient, and real-time offset the site change of the patient. In this way the doctor can accurately operate according to the simulative results. The experimental results show that this navigation system works well and improves the surgical precision
