Tracking accuracy of a stereo-camera-based augmented reality navigation system for orthognathic surgery

Tracking accuracy is critical to successful augmented reality (AR) in the diagnosis and surgical correction of maxillofacial deformities. The present study investigated the tracking accuracy of an AR navigation system combined with a stereo camera during repositioning of the maxilla after Le Fort I osteotomy, using a three-dimensional skull model, and compared the tracking accuracy with that of an existing infrared (IR)-based optical tracking system (OTS) navigation.
