摘要:

目的探讨作为前牙美容修复的金-瓷、铸瓷修复体在应用Crystaleye电脑比色仪比色时颜色的再现效果。方法对使用Crystaleye电脑比色仪比色后制作的金-瓷、铸瓷修复体(各58个)与作为比色参考的天然牙进行色差分析,并评价医生和患者的满意度。结果金-瓷修复体与天然牙的色差△E为7.13±0.74,铸瓷修复体与天然牙的色差△E为1.47±0.84,二者之间的差异有统计学意义(P<0.01)。铸瓷修复体的医、患满意度均高于金-瓷修复体,其差异有统计学意义(P<0.05)。结论Crystaleye电脑比色仪可以为铸瓷提供良好的比色参考,而对金-瓷修复体则有一定的偏差。

Abstract:

Objective To study the color reappearance effect of metal -ceram restoration and foundry -ceram restoration using Crystaleye spectrophotometer. Methods 58 metal-ceram restorations and 58 foundry-ceram restorations according to the result of the Crystaleye spectrophotometer were made respectively. The △E between restorations and natural teeth as referenced were analyzed. And satisfaction of dentists and patients were evaluated. Results The △E between metal-ceram restorations and natural teeth was 7.13±0.74. The △E between foundry-ceram restorations and teeth was 1.47±0.84. There were statistical differences between the △E(P<0.01). The satisnatural faction of dentists and patients to the foundry-ceram restorations were higher than to the metal-ceram restorations(P<0.05). Conclusion Crystaleye spectrophotometer can provide accurate reference for foundry-ceram restoration, but for metal-ceram restoration it is not accurate.
