The purpose of this study is to evaluate clinically the color reproduction system for ceramic restoration based on Computer Color Matching (0CM) which was developed in our department. In order to evaluate this system, the efficiency of color measuring system with Multi-spectrumm Camera and the precision of color reproducibility were analyzed in three dental institutioa Metal ceramic crowns were fabricated according to COM formulation to reproduce the color of target natural tooth for upper anterior mcisor, and the color of crowns were analyzed compared to target natural tooth. The following needs of improvement were suggested. (1)Miniaturization of the color measuring instrument, (2)Shortening of the color measuring time, (3)Color display for Multi-spectrum images, (4)Connection of color measurement and CCM calculation, (5)Developrnent of automatic weight measuring instrument for ceramic powder.The precision of color reproduction for incisal area was inferior compared to cervical and central area. Especially in case of low translucency and strong colored incisal area, the predicted result of CCM calculation and the color of CCM crowns was not adequate. It was suggested that the color space constructed by three shades of enamel ceramic in present system could not cover enough the color space for natural incisal tooth. In conclusion, shade and number for enamel ceramic and the method of CCM calculation for Incisal area should be reconsidered. The color of crown is very important factor for the esthetic dentistry. We will try to establish the CCM system with an intelligence net work in dentistry for next century.

本研究旨在对我科研制的基于计算机配色的陶瓷修复体色彩再现系统进行临床评价。为评价该系统，在3家口腔医疗机构对多光谱相机测色系统的效率和颜色再现精度进行了分析。按照COM配方制作金属烤瓷冠，再现上前牙的目标天然牙颜色，并与目标天然牙进行对比分析。提出了以下改进需要。（1）测色仪器的小型化，（2）测色时间的缩短，（3）多光谱图像的彩色显示，（4）测色与CCM计算的连接，（5）陶瓷粉末自动重量测量仪的研制。特别是在低透明度和切缘着色较强的情况下，CCM计算和CCM冠颜色的预测结果并不充分。结果表明，现有系统中由三种颜色的釉质陶瓷构建的颜色空间不能充分覆盖天然切牙的颜色空间。因此，应重新考虑搪瓷瓷的色调和数量以及切缘面积的CCM计算方法。牙冠颜色是影响美观的重要因素。我们将努力建立面向下世纪的具有智能化网络的口腔医学CCM系统。
