| 摘 要： | 目的 探讨在计算机上建立下颌骨牵张成骨三维有限元模型的方法。 方法 选择颅颌面发育正常青年男性,螺旋CT技术与计算机技术相结合,建立下颌骨牵张成骨三维有限元模型。 结果 首次模拟了骨皮质断开,并加入二腹肌前腹的边界约束,建立了三维有限元总体模型。 结论 模型有较高的相似性,为进一步研究人下颌骨牵张成骨奠定了基础。

| Abstract: | Objective To explore the method of establishing a three-dimensional finite element model of human mandibular distraction osteogenesis on the computer. Methods A young man with normal occlusion was chosen in this study. With the help of CT scanning and computer software, a three-dimensional finite element model was constructed. Results This model mimicked separation of cortical bone, together with the restriction of digastric muscle, to set up a model of human mandibular distraction osteogenesis. Conclusion The model's similarity to human body has been improved, which will benefit further study of mandibular distraction osteogenesis. |
