Abstract

As a combination of modern imaging technology, stereotactic technology, computer technology, and artificial intelligence technology, the surgical navigation system has been rapidly developed and applied in recent years. In recent decades, navigation systems have been used to aid in maxillofacial surgery, but rarely in the oral area. By comparing the applications of navigation systems in oral and maxillofacial surgery, we summarize their advantages and problems and list the advantages and disadvantages of the development process and methods of Simultaneous Localization and Mapping(SLAM). We propose to use tooth contours as natural markers to construct a model of AR oral structure, subtracting the operational time problems caused by making and using artificial markers. The AR structure model of the oral cavity was constructed, the method of applying SLAM technology to the oral surgery was proposed reasonably, and the method optimization scheme was proposed for the more complicated oral root canal surgery.
