摘　　要：烧烤次数增加、上釉方式不同是否会影响金瓷修复体的颜色这一问题尚存争议。本实验用WSC型测色色差计对不同烧烤次数及不同上釉方式的金瓷试件共40个进行了测试分析,结果表明:增加烧烤次数,采用不同上釉方式均可影响修复体的颜色。因此,笔者建议临床上应尽量减少金瓷修复体的烧烤次数,同时,最好使用一种上釉方式。The color of metal-ceramic samples which are fired in different times and differentglazed ways are measured by WSC colorimeter.The results shown:(1)The samples'value decrease and the chroma increase with increasing therepeated firing times.It indicates that we need to reduce the times of repeated firingtimes in order to avoid color change of restorations.(2)The chroma of the metal-ceramic samples glazed by selfglazing is higher thanthat glazed by appling glaze porcelain.It need to be studied further which glazed waymakes the color of metal-ceramic restorations better.
