Description

ABSTRACT:
A method is provided of coloring bakeable porcelain dental restorations. A plurality of pigmented coloring solutions is provided for application to a porcelain restoration. Each coloring solution comprises a pigment of low temperature porcelain-fusable powder and a substantially clear carrier liquid that supports a dispersion of said pigment and vaporizes when the restoration is baked. A film of the coloring solution is coated onto said restoration and then cured. The steps of coating the restoration and curing the film are repeated as necessary to match the color of the restoration to the color of a patient's teeth. The coated restoration is then baked to fuse the pigment to the porcelain and vaporize the cured carrier liquid.
