Dental mill blank with optimized color tone |
| abstract |
A dental mill blank can be fabricated, through a milling process, into a highly aesthetic dental prosthesis having an opalescent quality characteristic of natural teeth and also having a sufficient chroma level. Such a dental mill blank may include: 40 mass % or more of an inorganic filler, the dental mill blank satisfying conditions (1) and (2): (1) a specimen with a thickness of 1.20±0.01 mm has a chromaticity satisfying −0.5≤a* black ≤2.5 and 12.0≤b* black ≤25.0 in the L*a*b* color system when measured against a black background; and (2) the specimen with a thickness of 1.20±0.01 mm has an opalescence value of 17.5 or more. |
