摘要： The present invention concerns a method for manufacturing a glazed dental prosthesis, wherein the method comprises at least the steps of: a) providing a dental prosthesis body; b) position sensitive application of a predetermined amount of a glaze composition to at least a part of the dental prosthesis body surface, wherein the glaze comprises a heat sensitive coloring indicator and wherein this step is performed one or more times; c) controlling the applied glaze amount at least at one position of the glazed dental prosthesis body surface by assessing the color intensity at that position; and d) subjecting the coated dental body to a heat treatment to form the glazed dental prosthesis, wherein the temperature in the heat treatment is larger or equal to the de-composition temperature of the heat sensitive color indicator, thereby forming a leuko-form of the coloring indicator. The present invention further concerns the use of the inventive method for manufacturing a glazed dental prosthesis.

摘要： The invention relates to a method for printing a prosthetic tooth. A first step comprises segmenting an enamel part and a dentin part of a tooth to be replaced. Another step comprises modelling the enamel part and the dentin part of the prosthetic tooth, such that the enamel shape and the dentin shape of the prosthetic tooth correspond to the segmented enamel part and the segmented dentin part of the tooth to be replaced. The method also comprises generating a plurality of slices of the prosthetic tooth according to the enamel shape and the dentin shape, which are subsequently printed.

摘要： The invention relates to a method for producing a blank from a ceramic material, in particular a blank to be used for the production of a dental restoration, wherein at least two layers of ceramic materials of different compositions are filled in pourable condition layer-by-layer into a die and thereafter they are pressed and then sintered, wherein after filling of the first layer, a further layer of a ceramic material in pourable condition, which differs from the first layer, is filled into the die, in that the material of the first layer is mixed with the material of the further layer to form an intermediate layer, and then the second layer is filled into the die.
