牙冠三维演示模型建立方法的探讨

目的：初步探讨基于普通Windows平台的牙冠三维演示模型建立的方法。方法：通过获取牙冠石膏模型三轴外形轮廓及He龈向层面截面外形，在Windows98下，利用3Dmax软件重建牙冠三维模型。结果：寻求了一套简单、价廉、易操作的牙冠三维教学演示模型建立的方法。结论：该牙冠建模方法简单易行，可应用于实验课教学；建立的牙冠模型可供教学演示，网络教学，多媒体制作，为修复体设计三维预览奠定基础。

The research into construction of human teeth crowns three-dimensional model for demonstration

Objective: To develop a way of construction of human teeth crowns three-dimensional digital model fordemonstration in the Windows. Methods: The software 3Dmax was used to establish human teeth crowns three-dimensionaldigital model in the Windows environment, after acquiring 3-axis outline of the teeth crowns model as well as the 2ddigital data of continuous cross-sections in the occluso-gingival direction. Results: The way mentioned above, especiallywith the advantages of simplicity, low-price, feasibility and manipulability for undergraduate students in the labs, wasdeveloped successfully. Conclusion: The way of reconstruction of model may be used widely for undergraduate studentsin dental labs. And the model established may be used for educational demonstration, internet education, multi-mediaproducts and basis for 3d-design of dentures.
