摘要 目的观察自制玻璃渗透料P09728对CAD/CAM氧化铝渗透陶瓷颜色的影响。方法将20个CAD/CAM氧化铝渗透后瓷片(ALC瓷)分为四组各5个,A、B、C组使用自制玻璃料渗透,D组使用In-Ceram Vita AL3玻璃料渗透,采用美能达CR-100测色仪测量各组陶瓷修复体颜色空间(L*、a*、b*),计算色差(△E)。结果除A组、B组L*值及A组、C组b*值之间无统计学差异外,其余各组L*、a*、b*值之间均存在统计学差异(P均<0.01);四组陶瓷试件颜色变化中D组变化最大,C组颜色变化最小。结论自制玻璃料渗透氧化铝陶瓷颜色空间均在中国人牙的色度范围内,其明亮度较高,b*轴偏黄,符合中国人牙色特点。
