ABSTRACT:
A composite laminate dental veneer is provided for attachment to the labial enamel surface of a human tooth. In one form of the invention the dental veneer comprises an outer lamination composed of stain-resistant, chemical-resistant and erosion-resistant material and an inner lamination composed of a material having the capability of efficient bonding to the labial enamel surface of the tooth and having the capability of permanent attachment to the outer lamination in such manner as to define an integral veneer mass. The outer lamination may be composed of dense, stain-resistant materials such as cross-linked polymer and various vitreous materials such as ceramic material, glass and the like. The inner lamination may be composed of a noncross-linked polymer or a porous and cellular ceramic, glass or vitreous substance. The laminate veneer also employs a color system embodying an additive color system which includes color pigments of an enamel blend and a subtractive color system which includes color pigments of a dentin color blend. These color pigments would be distributed in color centers or microdots of color that are layered within an matrix.
