| ［摘要］ 目的 观察牙科低金含量银钯合金与另外两种烤瓷合金对金瓷修复体颜色的影响。方法 将三种合金分别铸造为圆盘试件各10个，上相同的遮色瓷、体瓷，测量不同合金材料对金瓷修复体颜色的影响。结果 在遮色瓷厚度0.1 mm，体瓷厚度1.1 mm情况下，三种不同合金材料制作的金瓷修复体在明度、色度、彩度方面未见显著性差异。结论 采用恰当的遮色瓷和体瓷厚度，钯基合金不会明显影响金瓷修复体的颜色。 |

| Abstract: |
| ［Abstract］ Objective To investigate the influence of experimental low-gold Ag-Pd alloy and two other dental casting alloys on the color of metal-ceramic restoration.Methods 10 disc samples were casted by each metal. The samples were covered by 0.1 mm OP and 1.1 mm dentin porcelain. The color of each sample was tested and the differences of three dental casting alloys were compared.Results There were no significant differences in L, C, H values of metal-ceramic restoration with the same thickness of OP and dentin porcelain by 3 different dental casting alloys.Conclusion There are no significant differences in lightness, chroma and hue of metal-ceramic restorations by 3 different dental casting alloys; Pd-based dental casting alloy cannot significantly influence the color of metal-ceramic restoration. |
