摘　　要：目的　采用三维层析测量技术建立人工树脂牙三维模型数据库。方法　利用CMS 4 0 0三维层析测量数字化仪对贺利三层色合成树脂牙模型进行逐层扫描 ,获得各树脂牙的表面三维数据点 ,并通过CAD软件的处理 ,建立各牙冠的三维图形。结果　三维层析测量技术能够获取人工树脂牙的表面三维数据 ,获得的树脂牙三维模型图像形态逼真 ,轮廓清楚。结论　三维层析测量技术可以准确测量复杂牙齿模型 ,避免了测量盲区的问题 ,为进一步开发全口义齿打下基础。Objective To establish 3D data-base on artificial resin teeth with 3D layer scanning digitizer. Methods Artificial resin teeth were measured with a CMS-400 3D digitizer by cutting and scanning layer-by-layer, 3D data points of each tooth acquired and the 3D models of these teeth reconstructed with a computer. Results 3D models of 3D data-base on artificial resin teeth were obtained. The characteristics of these 3D images were clear and accurate. Conclusion The complicated teeth moulds can be measured accurately with the 3D digitizer since there are no measuring blind spots.
