| 摘 要： | CAD技术应用于个性化基台的设计是口腔CAD／CAM系统的重要方向之一，研究了基于三次闭合均匀B样条自由变形的技术方法设计基台。首先利用基于Tailor级数的曲线细化方法生成B样条；然后基于参数化轮廓规则拉伸建模，形成基台的初始模型；最后通过实时地调整特征控制点进行基台的高度、角度以及颈缘线等局部变形。通过后槽牙的锥形基台设计应用实例证实研究算法的有效性、稳定性。

| Abstract: | The design of customized abutment based on CAD is one of the key steps of dental CAD/CAM. This paper presents a method based on cubic closed uniform B spline free -form deformation, proposes B spline based on Tailor series expansion, applies a regular extrusion modeling method based on parameterized contour to create the initial model of the abutment. So the angle height and cervical margins of the abutment are adjusted according to the charac- teristics control points. Some examples and the results show that the proposed algorithm is effective and feasible. |
