Abstract:
Objective This paper aims to explore the application value of mixed reality in oral and maxillofacial surgery and to conduct dynamic tracking using an in vitro model.Methods By collecting preoperative enhanced CT data of patients,rebuilding 3D digital model,combined with 3D printing technology,dynamic tracking of lesions was realized in the in vitro model,and the efficiency of different registration methods was compared.Results The 3D vi-sualized head and neck model was obtained by combining multiple anatomical models,and dynamic tracking was com-pleted in vitro.The average tracking time of the facial mark recognition method was T45°=3.67 frames,T90°=10.67 frames,and T total=12 seconds 28 frames(30 frames per second).The average tracking time of QR code recognition method was T45°=1.67 frames,T90°=2.33 frames,and T total=11 seconds 13 frames(30 frames per second).Conclu-sion The combination of MR technology and 3D printing technology can realize the dynamic tracking of lesions in vitro,which lays a foundation for the clinical applica-tion of MR technology to implement precise,personal-ized surgical programs.
