Effect of the metal ceramic restoration on detecting color using photoelectric colorimeter / 实用口腔医学杂志

ABSTRACT

Objective: To detect whether the metal base of the metal-fused-to-ceramic restoration have the same color performance and can be tested as natural teeth, and to evaluate whether they have effect on the color value determination by means of the photoelectrometer. Methods:Two kinds of shade guides of metal ceramic restoration were measured by photoelectric colorimeter, and color difference are analyzed compared with natural teeth of the same color. Results:The empfindung (color difference) of the shade guides with or without metal base and natural teeth is significantly different (P
