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 present invention relates to a mounting device adapted to be temporarily connectable ex-vivo to an unfinished dental prosthesis body in the course of dental prosthesis processing, wherein the mounting device at least comprises a lower base part and an upper connecting part, wherein the connecting part is adapted to be connectable to the void volume of the dental prosthesis body, wherein at least the connecting part comprises a porous material at least comprising a porous content of larger or equal to 15 volume-% and smaller or equal to 75 volume-% and a thermal conductivity at 800°C of larger or equal to 0.05 W/mK and smaller or equal to 0.75 W/mK. In addition, the present invention relates to a process for automated dental prosthesis processing.
