磨损引起的解剖轮廓变化是评价新修复材料的重要标准。本报告描述了一种结合计算机图形学和伺服液压技术捕获和显示解剖表面轮廓的方法。该方法可用于测量表面轮廓变化后的体积变化。使用含有两个体积为0.006 mm3和0.0281 mm3的小凹陷的样品评估该方法的准确度。该方法的记录精度分别为12%和2.5%。该方法的一个有用的特点是，图形使操作员能够可视化的磨损与表面解剖结构，除了定量测量它。
Change in anatomic contour due to wear is an important criterion in the evaluation of new restorative materials. This report describes a method of capturing and displaying anatomic surface contours using a combination of computer graphics and servohydraulics. The method can be used to measure the volume change following a change in surface contour. The accuracy of the method was assessed using a sample containing two small depressions of volumes 0.006 mm3and 0.0281 mm3. The recorded accuracies of the method were 12% and 2.5% respectively.A useful feature of the method is that the graphics enable the operator to visualize the wear in relation to the surface anatomy in addition to quantitatively measuring it.
