The invention relates to a method for manufacturing a colored block which contains zirconium dioxide and is intended for the manufacture of a dental restoration in which powder-based raw materials are mixed, at least some containing a coloring substance each. With zirconium dioxide as the main ingredient, the resulting mixture is pressed and subsequently subjected to at least one heat treatment. In order to generate the desired fluorescence, it is intended that in the powdered raw materials at least terbium, erbium, cobalt as a coloring substance will be used, as well as a substance that generates a fluorescence effect on dental restoration, but not iron. , in addition to natural impurities. |
