目的 建立带尖牙控轴托槽的下颌尖牙及其支持组织的三维有限元模型,初步进行有限元力学分析。方法 CBCT扫描获取下颌尖牙的断层图像,通过Mimics 14.0软件生成尖牙实体模型,并使用Pro/ENGINEER 4.0建模软件建立尖牙控轴托槽的实体模型,最后利用Ansya l4.5有限元分析软件建立有限元模型并进行分析。结果 建立了带控轴托槽的下颌尖牙及其支持组织的有限元模型,模型由5种材料属性、6个实体组成,具有良好的几何相似性和力学相似性,符合有限元计算要求,并初步分析了远中牵引尖牙的有限元力学情况。结论 本研究所建立的模型与临床情况接近,能够满足生物力学分析的要求,为进一步力学研究奠定理论基础。 |

Objective The present study aimed to construct three-dimensional finite element model of mandibular canine with adjustable-axis bracket. Methods The tomographic image of mandibular canine was obtained by CBCT scanning. By using the Pro/ENGINEER 4.0, Mimics 14.0, Ansya 14.5 softwares, the threedimensional finite element model of mandibular canine with adjustable-axis bracket was constructed. Results The three-dimensional finite element model of mandibular canine with adjustable-axis bracket was established successfully, which had 80905 elements and 148550 nodes in total. Conclusion The three-dimensional finite element model of mandibular canine with adjustable-axis bracket can effectively guide the bracket modification and clinical application. |
