| 摘 要： | 目的:建立人磨牙的三维模型,作为今后人体牙齿的进一步力学分析的基础。方法:采用年轻女性右侧下颌第一磨牙为对象,应用CT扫描技术、CT图像处理?熏 经过滤除噪声、重新排列、二值化等操作,用MathWorks公司的Matlab6.5的体积可视化功能来进行三维模型的建立。结果:采用CT薄层扫描资料建立起来的三维模型,形态逼真,能真实反映牙齿外形及髓腔三维结构。结论:人体磨牙三维模型的建立,可以为今后的牙齿生物力学分析提供一个逼真的模型,并且可进一步进行计算机辅助设计处理,建立的牙齿模型还可以进行生物力学分析以及动力学研究,为进一步研究奠定基础。

| Abstract: | Objective: To reconstruct three-dimension(3D) model of the first molar in human mandible and use it to analyse human molars. Methods: CT scans of the first mandibular molar and the data was put into medical soft in computer, then perform imaging processing. Put the data into matlab software to reconstruct the 3D model of the first molar. Result: The 3D model reconstructed by CT scan data, objectively reflected the real tooth figure and the pulp cavity figure of the tooth. Conclusion: 3D human molar provides an accurate model for biomechanical analysis, and can be used for the basis of further research. |
