目的：探讨应用模型外科技术在指导全面部骨折手术中颌骨复位、恢复咬合关系的作用。方法选择全面部骨折病例1例，介绍模型外科制作的全过程。利用镜像对称原理，在石膏模型上确定下颌牙弓宽度，再确定上颌咬合关系，制作咬合板。结果用咬合板引导，快速准确拼对咬合关系，指导骨折段复位，减少了术中骨块拼对时间和手术创伤，使手术顺利进行。患者术后咬合关系、面型恢复良好，未发生感染。结论模型外科在全面部骨折手术中有很好的指导作用，是全面部骨折手术中有价值的辅助手段，且简单易学，容易推广。

Objective To explore the application of model surgery in treating panfacial fracture.Methods 1 patient with panfacial fracture was reported,and the whole procedure of model surgery was introduced. Based on mirror symmetry principle,we first determined the width of the mandibular arch on model,and then the maxillary occlusion and made the occlusal guided plate.Results The patient was recovered to normal occlusion after operation and facial contour was satisfactory.Occlusal guided plate is very useful to the operation,which made the operation go on smoothly,reduced the operation steps,and saved operation time with fewer traumas.Conclusion The application of model surgery in treating panfacial fracture is useful.It is easy for us to perform the operation and apply the method to clinical practice.
