A method of coloring pre-sintered dental restoration, comprises: securing a pre-sintered dental restoration; applying a preceding liquid on the dental restoration; dipping the dental restoration, with the preceding liquid thereon, into a subsequent liquid for coloring; and sintering the dental restoration to acquire a fully sintered dental restoration. The subsequent liquid is different from the preceding liquid. The preceding liquid at least partly blocks or interferes with an infiltration of the subsequent liquid into an area where the preceding liquid was applied. The fully sintered dental restoration has less color/chroma in the area where the preceding liquid was applied.

1. A method of coloring a pre-sintered dental restoration, the method comprising, in sequence, the steps of: a) securing a pre-sintered dental restoration; and thenb) applying a preceding liquid on an incisal or occlusal area of the dental restoration; and thenc) dipping the dental restoration, with
1. A method of coloring a pre-sintered dental restoration, the method comprising, in sequence, the steps of: a) securing a pre-sintered dental restoration; and thenb) applying a preceding liquid on an incisal or occlusal area of the dental restoration; and thenc) dipping the dental restoration, with the preceding liquid in the incisal or occlusal area, into a subsequent liquid for coloring, the subsequent liquid being different from the preceding liquid, and with the preceding liquid at least partly blocking or interfering with an infiltration of the subsequent liquid into the incisal or occlusal area with the preceding liquid; and thend) sintering the dental restoration to acquire a fully sintered dental restoration with less color/chroma in the incisal or occlusal area, and more color/chroma in a body or cervical area, of the fully sintered dental restoration. 2. The method in accordance with claim 1, wherein the preceding liquid comprises deionized water, polyethylene glycol, and manganese chloride. 3. The method in accordance with claim 1, wherein applying the preceding liquid comprises applying the preceding liquid using a brush; wherein dipping the dental restoration comprises immersing the dental restoration into the subsequent liquid. 4. A method of coloring a pre-sintered dental restoration, the method comprising, in sequence, the steps of: a) securing a pre-sintered dental restoration; and thenb) applying a dental liquid on an incisal or occlusal area of the dental restoration; and thenc) sintering the dental restoration to acquire a fully sintered dental restoration having a translucency and color intensity/chroma with an inverse relationship with the translucency increasing in one direction of the dental restoration and the color intensity/chroma decreasing in the same direction of the dental restoration. 5. The method in accordance with claim 4, wherein the dental liquid comprises manganese chloride. 6. The method in accordance with claim 4, wherein the fully sintered dental restoration displays a multiple color intensity effect with less color/chroma in the incisal or occlusal area, and more color in a body or cervical area. 7. A method of coloring pre-sintered dental restoration, the method comprising, in sequence, the steps of: a) securing a pre-sintered dental restoration; and thenb) applying a preceding liquid on the dental restoration; and thenc) dipping the dental restoration, with the preceding liquid therein, into a subsequent liquid for coloring, the subsequent liquid being different from the preceding liquid, the preceding liquid at least partly blocking or interfering with an infiltration of the subsequent liquid into an area where the preceding liquid was applied; and thend) sintering the dental restoration to acquire a fully sintered dental restoration with less color/chroma in the area where the preceding liquid was applied. 8. The method in accordance with claim 7, wherein the preceding liquid comprises deionized water and polyethylene glycol. 9. The method in accordance with claim 7, wherein applying the preceding liquid comprises applying the preceding liquid using a brush; wherein dipping the dental restoration comprises immersing the dental restoration into the subsequent liquid.
