应用激光扫描法实现磨牙金属全冠三维重建的实验研究

An experimental study of three-dimensional reconstruction of the molar full metal crown with laser scan

目的:实施磨牙金属全冠的三维重建。取得全冠的数字模型,以便于有用快速成型的方法制作磨牙金属全冠。方法:应用台湾区CNC镭射扫描系统,将金属全冠的蜡型进行扫描,在计算机中形成全冠的三维图像。应用逆向工程软件形成全冠的数字模型。结果:得到了全冠的三维重建数字模型,其文件为STL格式。结论:重建方法可行,所得数字模型可用于全冠的计算机辅助制作。

Objective: To achieve the three-dimensional (3-D) reconstruction of the molar full metal crown. Methods: By using CNC laser scan system, the wax pattern of full crown was scanned and the 3-D shape was retrieved in the computer. Results: 3-D digtal models were retrieved with STL file. Conclusions: The way of reconstruction might be applied for CAD/CAM of full crown.
