摘要
目的 :实现标准牙冠的整体几何变换以及咬合面局部的微小形变 ,模拟修复体的咬合调整。方法 :利用Matlab软件平台编写程序 ,在标准牙冠的表面定义特征点和特征区 ,利用矩阵运算的方法对标准牙冠的三维数据进行各种数学变换。结果 :重建了标准牙冠的三维图形 ,实现了牙冠的空间整体几何变换和局部形变。结论 :模拟了修复体咬合调整的过程 。
Objective: To realize the deformation of the standard tooth crowns and simulate occlusal adjustment of prosthesis. Methods: 2 program was write based on the software of Metlab. Characterized areas and points were defined on the surfaces of the virtual crowns. The crowns were varied and adjusted using the programs. Results: The 3-D graphs of standard teeth crowns were reconstructed. The translation, rotation and deformation of the virtual crowns were realized by utilizing different varies of the programs. Conclusion: The occlusal adjustment of the prosthesis can be simulated by the programs, and the programs may be used in dental CAD.
