正颌手术是治疗牙颌面畸形的经典手术。由于牙颌面解剖结构的复杂性，术前通常需要进行详细而准确的手术规划。随着近年来医学成像技术和手术规划软件的快速发展，虚拟手术规划(VSP)越来越多地被用于正颌外科，以提供准确、高效、可预测的规划和模拟。正颌外科VSP的设计和发展涉及图像采集和复合头部模型构建、三维参考框架定义、虚拟咬合设置、虚拟截骨和手术模拟、软组织预测、转移工具等几个方面，该文对相关步骤的研究进行了总结，以为临床提供参考。 Orthognathic surgery is a classic procedure to correct dentomaxillofacial deformities. Due to the complexity of the dentomaxillofacial anatomy, detailed and accurate surgical planning is usually required before the operation. With the rapid development of medical imaging technologies and surgical planning softwares in recent years, virtual surgical planning(VSP) has been increasingly applied in orthognathic surgery to provide more accurate, efficient and predictable planning and simulation. The design and development of VSP in orthognathic surgery involves image acquisition and composite head model construction, three-dimensional reference frame definition, virtual occlusion setup, virtual osteotomy and surgical simulation, soft tissue prediction and transfer tools. This paper summarizes the research of related steps for clinical reference.
