This study was designed to investigate the measurement of the occlusal contact area (surface) using commercially available equipment and computer programs for image processing and analysis. A stable occlusal record was made using an addition curing silicone rubber putty and was placed on a light source onto which a video camera was focused. This image was digitized and standard thickness records were used to calibrate the appropriate threshold for measurement of contact and near contact surfaces. Differences between individuals and within individuals with and without their partial dentures are large. This method has the potential to be a powerful tool in the study of occlusion.
本研究旨在使用市售设备以及用于图像处理和分析的计算机程序来研究咬合接触面积（表面）的测量。使用加成型硫化硅橡胶腻子制作稳定的咬合记录，并将其放置在摄像机聚焦的光源上。该图像被数字化，并且使用标准厚度记录来校准用于测量接触表面和近接触表面的适当阈值。佩戴和未佩戴局部义齿的个体之间以及个体内部的差异都很大。这种方法有可能成为咬合研究中的有力工具。
