摘要： To make a color tone similar to that of dentin of a tooth at a low cost without discoloration when baking, a dental ceramics material is produced by: mixing a pink coloring agent and a yellow coloring agent with zirconium oxide containing a stabilizer while having a mixing ratio of 0.001 to 5 wt. % respectively; and baking it, where the pink coloring agent is obtained by dissolving manganese oxide in aluminum oxide as a solid solution, the yellow coloring agent is obtained by dissolving vanadium oxide in zirconium oxide as a solid solution, the zirconium oxide contains 0.1 to 30 wt. % aluminum oxide if necessary, the stabilizer is one or more kinds selected from a group including yttrium oxide, magnesium oxide, calcium oxide, and cerium oxide, and the content thereof is preferably 3 to 7 wt. %.
