颜面部缺损修复体配色的色度学研究

A study of color matching of maxillo facial prosthesis

颜面软组织缺损修复中，修复体的颜色与肤色不吻合的问题一直困扰着医患双方。本研究试图通过把色度学及相关仪器引入颜面软组织缺损修复体的配色研究中来提高缺损修复体的颜色仿真性。参照肤色范围，以红、黄、白和黑色颜料与硅橡胶配色、测色。对颜料的配比值和相应色块的色度值进行多元回归分析，建立起颜面软组织缺损修复体配色的数学模型。

The color differences between the patients facial prosthesis and the surrounding skin have long puzzled both of dentist and patient.The purpose of the study was to introduce spectrophotometer into the color matching and set up a set of equations to increase the accuracy of the color matching.Referring to increase the accuracy of the color matching.Referring to color gamut,several sets of shade guide were made according to sixteen kinds of mixture ratio of four pigments such as red,yellow,white and black,and every shade guide was measured.The mixture ratio was related to the values of the CIE system by means of statistics,which resulted in the equations for color matching.In a word,use of the spectrophotometer may improve the accuracy of the color matching of facial prosthesis.
