[摘要]目的：探讨不同颜色不同厚度的瓷贴面能否恢复对应Vita比色的牙齿的原来颜色以及不同颜色的粘结树脂对其颜色的影响。方法：制作不同颜色（A1、A2、A3色）不同厚度（0.50mm、0.75mm、1.00mm）的Cerinate瓷贴面，将其用不同颜色的粘结树脂粘固到对应的牙齿预备面上，用测色仪分别测量牙齿预备前及粘固了Cerinate瓷贴面后牙面的L*a*b*值，比较两者的差异。结果：随着预备深度的增加，两者的L*a*b*值越来越接近，不同颜色的粘结树脂对其色彩的影响越来越小。结论：Cerinate瓷贴面可以恢复牙齿原来的颜色，不同颜色的粘结树脂对Cerinate瓷贴面修复的最终颜色有微调作用。

Abstract: Objectives To evaluate whether Cerinate Porcelain Veneers can recover the color of teeth in different preparation depth and the effect of luting resin to the final color of the restorations. Methods Samples of Cerinate Porcelain Veneers were prepared in different thickness(0.5mm、0.75mm、1.00mm)and different Vita shade(A1、A2、A3).Luting resins of different colors were used to lute these samples on teeth surface with different preparation depth.Colorimeter was used to measure the L*a*b* of the teeth surface without preparation and after covering with Cerinate Porcelain Veneers. Results With the preparation depth increasing,these two values of L*a*b* are coming close and the color of the luting resin has smaller effect to the final color of the restoration. Conclusion Cerinate Porcelain Veneers can properly recover the colors of teeth and different colors of luting resins can slightly adjust the final color of Cerinate Porcelain Veneer restorations.
