| A novel navigation system for maxillary positioning in orthognathic surgery: preclinical evaluation Aug 22nd 2015, 00:38, by Lutz Jean-Christophe, Nicolau Stéphane, Agnus Vincent, Bodin Frédéric, Wilk Astrid, Bruant-rodier Catherine, Rémond Yves, Soler Luc Appropriate positioning of the maxilla is critical in orthognathic surgery. As opposed to splint-based positioning, navigation systems are versatile and appropriate in assessing the vertical dimension. Bulk and disruption to the line of sight are drawbacks of optical navigation systems.Our aim was to develop and assess a novel navigation system based on electromagnetic tracking of the maxilla, including real-time registration of head movements. Since the software interface has proved to greatly influence the accuracy of the procedure, we purposely designed and evaluated an original, userfriendly interface. |
