Zusammenfassung:The invention relates to a colored zirconia dental restoration prepared based on zirconia powder properties and a preparation method thereof, the method comprises the following steps: firstly determining the properties of a white zirconia powder raw material and whether the white zirconia powder raw material is granulated powder, and then adopting different coloring modes according to the properties of the powder raw material, the white zirconia powder raw material is non-granulated powder, and the white zirconia powder raw material is non-granulated powder. Adding a coloring oxide accounting for 0.1-5% of the mass of the raw materials, and mechanically and uniformly mixing to obtain colored zirconium oxide powder; the powder raw material is granulation powder, a coloring solution accounting for 1-10% of the mass of the raw material is uniformly sprayed, and the coloring zirconia powder is obtained through drying; and forming, pre-sintering, cutting and finally sintering to obtain the colored zirconia ceramic
