ABSTRACT:
Low viscosity dental restorative coating compositions for application to natural and to artificial teeth, useful in covering surface imperfections including stains, gumline erosion, small pits, and the like. They are designed to impart to restored teeth the overall appearance of original teeth, particularly with respect to natural vitality and fluorescense, while effectively masking stains and themselves resisting discoloration from staining agents and upon aging. They are formulated to bond well, look natural, and wear well. As ready to use, a coating composition will contain from about 30% to about 70% filler by weight of the composition, in a resinous, curable liquid vehicle. The composition is formulated to be sufficiently fluid so that it can be applied to a dental surface easily and conveniently, as by brushing on a previous prepared surface, and it will flow to a featheredge. The composition nevertheless must be sufficiently viscous that dripping from the applicator, generally a brush, and dripping from the coated surface, are essentially absent. The filler is a blend of glass or silica and a fluorescent pigment. Also used are inhibitors, curing agents including peroxide catalysts and accelerators, dyes, ultraviolet absorber materials, and additives that retard settling.
