摘　　要：目的通过数字化软件对牙颌面畸形患者进行正颌术前模拟设计,将得到的数据应用于临床手术中以指导术者对牙颌面畸形进行精确的手术治疗。方法选择2012年1月至2013年1月到中国医科大学附属口腔医院口腔颌面外科就诊的牙颌面畸形患者15例,进行术前三维CT扫描,将CT数据输入proplan软件系统中。通过软件重建上下颌骨,在三维方向上对颌骨进行定点、截骨、移动骨段、模拟预测等操作,确定手术方案后保存数据。术中按照软件模拟方案进行手术。结果 15例患者手术顺利,术中未出现严重并发症。术后半年随访,满意率达到93.3%。结论采用数字化软件对牙颌面畸形患者进行术前模拟设计是一种较为精确的方法,可直观模拟手术并预测术后效果,从而为正颌外科矫治复杂牙颌面畸形制定个体化最佳手术方案提供实用有效的技术和依据。Objective To make doctor perform operation accurately on patients with dentomaxillofacial deformity by preoperative simulation based on digital data which was collected by digital software.Methods Fifteen patients had previously undergone 3-dimensional computed tomography and the data from CT scan were input into digital software. We used the software to simulate operations preoperatively including fixing point,osteotomies and movements of jaw bones.The collected information from software was applied to actual operations.Results All the operations had been completed successfully without serious complication. The patients were satisfied with the effect of operation 6 months after operation,with a satisfaction rate of 93.3%.Conclusion The digital simulation technique is a precise method which provides practical and effective basis for establishing the preoperative planning of individual optimal surgical procedure for patients with dentomaxillofacial deformities in orthognathic surgery.
