Development of a robot-assisted orthognathic surgery system integrated with image-guided navigation

Summary form only given. The aim of this study was to develop a robot-assisted system for orthognathic surgery and to evaluate robot movement. The registration procedure was performed in coordinates among a robot, an optical tracking system (OTS) and a CT image with fiducials. According to the surgical plan in the CT coordinate, the robot arm moved to the corresponding robot position. The results were below 0.15mm in translational movement and below 0.41mm in rotational movement.
