Abstract:
A method of coloring a pre-sintered dental restoration comprises securing a pre-sintered dental restoration having multiple different layers having a different chemical composition of color pigments between adjacent layers; dipping the pre-sintered dental restoration into a coloring liquid, and sintering the pre-sintered dental restoration to acquire a fully sintered ceramic restoration having a translucency and color intensity/chroma with an inverse relationship with the translucency increasing in one direction of the restoration and the color intensity/chroma decreasing in the same direction of the restoration.

Claim (Index 6):
A method of coloring a pre-sintered dental restoration, the method comprising, in sequence, the following steps of:\n a) securing a pre-sintered dental restoration having multiple different layers with each layer having a different chemical composition of color pigments between adjacent layers, including different amounts of yttria between the adjacent layers, with the amount of yttria increased from the lower layer to the upper layer, and then b) dipping the pre-sintered dental restoration into a coloring liquid, and then c) sintering the pre-sintered dental restoration to acquire a fully sintered ceramic restoration having a translucency and color intensity/chroma with an inverse relationship with the translucency increasing in one direction of the restoration and the color intensity/chroma decreasing in the same direction of the restoration.
