数字化三维手术模拟在正颌外科专科医师培训中的应用

摘要

牙颌面畸形患者面部形态异常和咬合功能障碍常较严重，需要采用正颌—正畸联合治疗的方法进行矫正。治疗牙颌面畸形的正颌手术术野狭小、操作复杂、风险较大，其手术教学和操作培训手段有限，限制了此类技术的推广应用。文章介绍了将数字化三维手术设计与模拟系统应用于正颌外科专科医师培训，可取得良好的手术教学效果。实践表明，通过手术虚拟操作，可使受训医师加深对牙颌面畸形和正颌外科手术的理解。%Patients with dento-maxillofacial deformities often suffer relatively severe facial anomalies and occlusal dysfunction, which need to be corrected with combined orthodontic and orthognathic treatment.Orthognathic surgery is very complicated with narrow operative field and relatively high risk.The means of orthognathic surgery teaching and operation training are limited,which restricts the promotion of orthognathic surgical technology.In this study,a digital three-dimensional surgical design and simulation system was applied to specialist training of orthognathic surgery with satisfactory results.Practice proves that through virtual operation training,the trained surgeons obtained a deeper understanding of dento-maxillofacial deformities and orthognathic surgery.
