METHOD OF FORMING A DENTAL COPING IN A SINGLE HEAT TREATMENT FROM A COMPOSITE MATERIAL OF AT LEAST TWO LAYERS AND TO A MULTILAYERED COMPOSITE MATERIAL FOR FORMING A DENTAL CROWN

摘要

A dental material and method for forming a dental coping wherein the material has a plurality of layers with at least one layer composed of a base material composition containing high fusing temperature metal particles and with at least another layer being composed of a filler material composition of low fusing temperature metal particles arranged in an alternating sequence such that upon firing of the laminated structure in a furnace at a temperature at least equal to the melting temperature of the low fusing temperature metal particles but below the melting temperature of the high fusing temperature metal particles diffusion occurs from the filler layers into the base layers to bring the base layers together to form a solid structure.
