中文摘要	目的:测定牙科CAD/CAM用氧化铝玻璃复合体系统的颜色,为临床应用奠定基础。方法:选用自行研制的CAD/CAM氧化铝玻璃复合体的AG1、AG2、AG3、AG4色系及VitaIn CeramAL1、AL2、AL3、AL4色系的渗透玻璃粉,对牙科CAD/CAM用氧化铝块进行渗透,制作 10mm×10mm,厚度分别为 0. 5、1、1. 5mm的颜色测量试样,采用分光测色计对颜色进行测定。结果:以 1mm厚度样本为标准,VitaIn CeramAlumina范围为L*: 69. 39~78. 41,a*: 1. 82~4. 02,b*: 18. 35 ~24. 42;CAD/CAM用氧化铝玻璃复合体系统的颜色范围为L*: 68. 80~78. 44,a*: 1. 32~4. 75,b*: 16. 86~21. 86。不同的是AG3铝瓷的b*值和饱和度较AL3铝瓷低,a*值较高;AG1和AG2铝瓷的b*值和饱和度较AL1和AL2铝瓷偏低。2种体系的可见光谱反射率相近。结论: CAD/CAM氧化铝玻璃复合体色系与VitaIn CeramAlumina材料色系的颜色范围近似,可以满足与表面饰瓷颜色匹配的要求。; Objective: To measure the color of dental CAD/CAM alumina-glass-composites(AGC). Methods: Dental CAD/CAM alumina block were infiltrated at 1 120 ℃ by laboratory made AG1,AG2,AG3 and AG4 color serials of infiltration glass powder and Vita In-Ceram Alumina AL1,AL2,AL3 and AL4 infiltration glass respectively. Specimens were made with the area of 10 mm×10 mm,thickness of 0.5,1 and 1.5 mm respectively. Color parameters were measured by Minolta CM-2600d spectrophotometer. Results:The specimen with the thickness of 1 mm was used as the standard for color measurement.After infiltration with AL1-AL4 glass powder,the color parameters of Vita alumina core ceramic were L*: 69.39-78.41,a*:1.82- 4.02,b*:18.35-24.42,when infiltrated with AG1-AG4 glass powder, the color parameters of CAD/CAM AGC were L*:68.80-78.44,a*:1.32- 4.75,b*:16.85- 21.86. b*value and chroma of the AG3 core ceramic were lower than that of AL3 core ceramic,while a* value was higher.b* value and chroma of the AG1 and AG2 core ceramic were lower than that of AL1 and AL2 core ceramic. The reflectance curve of CAD/CAM AGC infiltrated by AG1-AG4 glass powder demonstrated the similar trend as that of the core ceramic infiltrated by Vita In-Ceram glass powder. Conclusion: The color range and surface reflection rate of laboratory made AG1-AG4 AGC are similar with those of Vita AL1-AL4 In-Ceram Alumina core and may meet the need of color match with veneer ceramics.; 全军医学科学技术研究“十五”计划面上项目资助(01MA198)
