一种新的计算机辅助颌骨矫形手术系统已被开发并应用于临床。它结合了三维(3-D)手术规划和传统的牙齿咬合规划。开发的软件可以在计算机断层扫描(CT)生成的面部骨骼的虚拟3-D模型上模拟手术矫正。手术规划和仿真包括动态头影测量、半自动镜像、交互切割和节段定位。通过将软件与跟踪系统相结合，并在特殊注册程序的帮助下，我们能够从石膏模型支架上获得牙齿咬合计划。手术计划完成后，该装置用于制作用于术中指导的定位夹板。该系统借助显示颌骨位置的显示器和在手术过程中实时更新的3-D定位指南，提供进一步的术中辅助。提出的方法提供了三维可视化和跟踪技术的优势，而不牺牲长期证明的基于CAST的技术来评估牙齿咬合。该系统已在一名患者身上应用。在整个过程中，我们经历了病理评估的改进、精确度的提高和控制的加强。
A new system for computer-aided corrective surgery of the jaws has been developed and introduced clinically. It combines three-dimensional (3-D) surgical planning with conventional dental occlusion planning. The developed software allows simulating the surgical correction on virtual 3-D models of the facial skeleton generated from computed tomography (CT) scans. Surgery planning and simulation include dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and segment repositioning. By coupling the software with a tracking system and with the help of a special registration procedure, we are able to acquire dental occlusion plans from plaster model mounts. Upon completion of the surgical plan, the setup is used to manufacture positioning splints for intraoperative guidance. The system provides further intraoperative assistance with the help of a display showing jaw positions and 3-D positioning guides updated in real time during the surgical procedure. The proposed approach offers the advantages of-3-D visualization and tracking technology without sacrificing long-proven cast-based techniques for dental occlusion evaluation. The system has been applied on one patient. Throughout this procedure, we have experienced improved assessment of pathology, increased precision, and augmented control.
