Abstract

A coloring liquid especially for shading pre-sintered ceramic dental restorations, utilizes a combination of metal salt, solvent and acid to achieve natural tooth coloring of standard dental shades. By adjusting the respective ingredients, different shades can be provided and color penetration can be sufficient to preserve aesthetics in the sintered restoration even when some of the ceramic material is removed.
