ABSTRACT:
Two dispersant compositions are disclosed for use in the fabrication of a dental prosthesis, the compositions serving for the dispersion and deposition of an opacifier layer and a porcelain color layer over the opacifier layer. The dispersants are so formulated that only a single firing is used to produce both the opaque and porcelain bisque simultaneously, whereas prior methods required firing of the opaque layer prior to application of the porcelain color layer. A method of application to insure effective hiding of the metallic substrate, especially near the gingival portion, is disclosed.
