下颌磨牙全冠计算机辅助设计初步

A primary study on the methodology of computer aided design of complete crown of mandibuler molar

目的：尝试构造标准人造全冠数据库的方法。方法：应用ＵＧ软件和二次开发程序，以人机对话方式，按全冠设计原则完成全冠计算机辅助设计（ＣＡＤ）。结果：建立了下颌磨牙标准全冠实体模型。结论：所选方法可行，为进一步在牙全冠预备体上设计全冠奠定了基础。

Objective: To develop a new method for constructing database of standard artificial complete crown of mandibular molar. Method: According to design principle of complete crown, UG software and relative program developed by ourselves were applied to accomplish computer aided complete crown design by manmachine conversation. Results: A standard mandibular molar visual model was established. Conclusion: The method may be applied for computer aided complete crown design.
