摘　　要：目的建立上颌骨复合体战、创伤三维有限元模型,为颌面部战、创伤提供生物力学分析依据。方法用螺旋CT断层扫描技术,应用Mimics软件辅助快速建立上颌骨复合体三维有限元模型,在模型上进行颌面骨载荷作用下碰撞实验。结果快速建立上颌骨复合体有限元模型,在冲击载荷时,上颌骨复合体Von-Mises应力在撞击处为2607.10kPa(1kPa=7.5mmHg);鼻底部为2313.35kPa;鼻根点为2008.45kPa;颧额缝为3518.69kPa;颧牙槽嵴为2195.95kPa;翼上颌缝为2113.54kPa;硬腭后部为1880.23kPa;颧弓为1653.88kPa。结论利用Mimics建立上颌骨复合体战、创伤三维有限元模型,有较高的真实性和精确的度。能够满足颌面部战、创伤生物力学分析需要。Objective To construct three dimensional finite element model of maxillary complex with warwound in order to provide the foundation of studying maxillofacial trauma. Methods A three dimensional finite element model of maxillary complex was constructed by thin-layer CT and Mimics software. And making impact text. Results Constructing a three dimensional finite element model of maxillary complex, in the impact text, the Von-Mises srtess distribution of maxillary complex as： impact place was 2 607.10 kPa;basis nasi was 2 313.35 kPa; radix nasi was 2008.45 kPa; sutura nygomaticofrontalis was 3 518.69kPa; maxilla zygomatic crest was 2 195.95 kPa; pterygomaillary is 2 l13.54kPa; palatum durum is 1 880.23 kPa; zygomatic arch is 1 653.88 kPa. Conclusion The contructed maxillary complex model is real and accurate. And it can provide the foundation of studying biomechanics mechanism of maxillary fracture in war-wound.
