摘 要: | 目的:利用Matlab和Pro/E软件辅助建立桩核冠三维有限元模型。方法:应用Matlab软件编程读取通过CT扫描所获取的建模所需二维影像图像(共45张,层厚0.5mm,无间隔)的边界数据;再利用Pro/E的自由曲面造型和加减布尔运算建立桩核冠各个三维实体模块模型,并进行三维重组;最后在Ansys中进行模型单元划分和力学检测。结果:建立包含饰瓷、金属基底、桩核、粘固剂、牙本质、牙胶尖、牙周膜、松质骨和皮质骨的三维有限元模型。结论:利用Matlab软件和Pro/E软件辅助建模,提高了建模的精度、速度和灵活性,为临床口腔医师进行有限元生物力学分析研究提供了一种简捷而精确的有限元建模方法。

Reconstruction of Three-dimensional Finite Element Model of Post Crown with Matlab and Pro/E Software |
| |
Abstract: | Objective: To explore an easier and more precise method to reconstruct 3D finite element model of post crown with Matlab and Pro/E. Methods: Thin-layer CT scanning was used to obtain morphological pictures of post crown. Matlab and Pro/E software were used to acquire the data and to reconstruct the 3D finite element model of post crown. Results: A more precise and widely used 3D finite element model of post crown, cement,crown, dental root, gutta percha point, periodontal membrane, cancellous bone, and cortical bone. Conclusion: With Matlab and Pro/E software, dentists can reconstruct the model precisely, quickly and flexibly. |
