Abstract
VR and AR technology have gradually developed to the extent that they could help operators in the surgical field. In this study, we present a case of VR simulation for preoperative planning and AR navigation applied to orthognathic surgery. The average difference between the preplanned data and the post-operative results was 3.00 mm, on average, and the standard deviation was 1.44 mm. VR simulation could provide great advantages for 3D medical simulations, with accurate manipulation and immersiveness. AR navigation has great potential in medical application; its advantages include displaying real time augmented 3D models of patients. Moreover, it is easily applied in the surgical field, without complicated 3D simulations or 3D-printed surgical guides.
Highlights
Reality (AR) Navigation in Orthognathic surgery is a popular surgery performed by oral and maxillofacial surgeons
Preoperative planning for orthognathic surgery was performed in a virtual space
It was shown that virtual reality (VR) simulation could provide easy handling of 3D models, for adjusting the maxilla and mandible with intuition
Summary
Reality (AR) Navigation in Orthognathic surgery is a popular surgery performed by oral and maxillofacial surgeons. AR can provide the operator with a 3D computer-generated model superimposed onto real objects, all in real time [5] When using this as a navigation system, it is possible to provide immediate guidance by intuitively expressing necessary information for the surgeon, such as anatomical structure in a deep area or as accurate surgical guidance. It is expected that the accuracy of the operation will be improved and the operation time will be reduced It can provide more clear information, make the users improve safety, and lower the risks [6]. As image recognition and tracking technology improve gradually, real patient can be tracking by combining with camera system and optical markers This presents the application of VRsystem planning an AR-guided system real patient bestudy tracking by combining with camera andand optical markers. Study presents the application of VR planning and an AR-guided system for orthognathic surgery in Class III dentofacial deformity patient
