| 摘 要： | 提出了在约束条件下基于直接操作自由曲面变形修复冠的变形设计方法，完全以患者口腔内的约束条件为基础，通过对特征位置增加、修改、删除约束点和载荷点，再对上述点施加拉伸和压缩，从而获得适合的牙冠修复模型。最后，通过一个牙冠修复体变形设计的例子，说明该方法的有效性。

| Abstract: | A flexible and adaptable design method for the tooth crown is presented based on the direct manipulation of free-form deformation (FFD). The correct shape of the tooth crown can be obtained by adding, modifying, and deleting constraint points or load points based on stretching and compressing operation. Finally, an example is given to illustrate the method to be efficient. |
