14h40 Computer-Assisted Navigation in Orthognathic Surgery.

Summary: Maxillofacial surgery is undergoing a major transformation thanks to the integration of digital technologies. The use of 3D and intraoral scans for preoperative planning, combined with the use of 3D printers to create models and custom splints, represents a significant advancement in the pre-surgical process. These tools also provide greater autonomy to the department that uses them.

The aim of this presentation is to present a case of orthognatic surgery, which intergrates neuro-navigation.

This technology allows measurement of intraoperative surgical movements, enabling comparisons with those predicted during the initial digital planning. The goal of this pilot study case is to determine the accuracy of the performed displacements as well as the precision of the splints, identifying any differences with the prior planning. This direct comparison between planning and surgical reality opens new perspectives for significantly improving the precision of orthognathic procedures.
