摘要： A process for the preparation of multi-coloured glass ceramic blanks for dental purposes is described, in which lithium silicate glasses with different compositions are introduced into a mould in order to form a glass blank, the glass blank is optionally compacted by pressing, the glass blank is heat-treated in order to obtain a glass ceramic blank with lithium silicate as main crystal phase, and the glass ceramic blank is compacted by hot pressing.

摘要： A device for producing dental ceramic, with a CAD/CAM device for preparing a compression molding cavity for producing the dental ceramic, wherein a CAD device thereof, on the basis of scan data, determines the shape of the dental ceramic to be produced, and wherein a CAM device thereof produces a positive model, on the basis of which the mold cavity is produced via a sacrificial mold (muffle). The CAM device also determines the distribution and the transfer between different ceramic types, i.e. types of ceramics that differ at least in respect of one parameter in terms of material, appearance, strength or the like, wherein the CAM device for adjusting the distribution and the transfer determines the position and the dimensions of a feed channel between a muffle rod and the compression molding cavity for producing the dental ceramic according to at least one of these parameters.
