Augmented reality for oral and maxillofacial surgery: The feasibility of a marker‐free registration method

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: Recognition of markers in the augmented reality system can reduce the additional cost of a guide plate required for the removal of benign tumours in oral and maxillofacial surgery, but the use of markers often has complex problems. METHOD: In order to avoid the complex problem of using markers, an augmented reality system based on a marker-free registration method was proposed to track the contour of the mandible edge. Use the computer to perform preoperative planning on the jaw model, select and mark the path of maxillofacial lesion resection. RESULTS: mm. CONCLUSIONS: We demonstrate that the system can accurately enhance the display of the surgical path and provide guidance for the tradition of maxillofacial surgery.
