Document Type and Number:
Japanese Patent JP6917679
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a ceramic blank for multilayer-structure dental cutting processing close to the tone of a natural tooth.SOLUTION: The ceramic blank for dental cutting processing comprises a four-or-more-layer structure in which an E layer (L, C) with the lowest saturation and a C layer (L, C) with the highest saturation are arranged respectively in parallel and an M layer (L, C) are located in parallel in the middle of the two layers. In the ceramic blank, the lightness L* and the saturation C* of each layer satisfy the following relations: L=(L+L)/2×0.97 to 1.03, C=(C+C)/2×0.93 to 1.07, C>C>C.SELECTED DRAWING: None
