| 摘 要： | 目的 利用激光三维扫描技术重建下颌骨三维结构，探索建立有限元几何模型的新方法。方法 利用激光三维扫描系统．多次、分区域地扫描人体下颌骨标本并形成下颌骨表面轮廓点云文件，然后对扫描点云文件进行拼接，重建下颌骨表面轮廓。结果 建立了一个人体下颌骨骨性表面的三维模型。此模型造型逼真，并可以适当的文件格式应用于有限元结构力学仿真分析。结论 在生物力学仿真实验中，激光三维扫描系统可以用于建立有限元几何模型，可解决常规CAD(computer aided design)方法难以建立非规则人体结构模型这一难题。

| Abstract: | OBJECTIVE: To construct a three-dimensional (3D) mandibular model using a 3D laser scanner, and explore a new method for reconstructing the finite element geometry model. METHODS: A mandible specimen was scanned with the 3D laser scanner to form the point clouds of the mandibular surface, which were subsequently aligned for reconstruction of the mandibular model. RESULT: A 3D model of the mandible surface was reconstructed, which could be used for finite element simulation. CONCLUSION: The 3D laser scanning system can be used to reconstruct the 3D model with irregular geometry for finite element simulation. |
