Abstract: The invention relates to a blank from a ceramic material, wherein at least two layers of ceramic material of different compositions are filled into a die layer-by-layer and after filling of the layers they are then pressed and sintered, wherein after filling of a first layer this is structured on its surface in such a way that the first layer, viewed across its surface, differs in its height from region to region, and then a layer with a composition that differs from the first layer is filled as a second layer into the mold.

Abstract: The invention relates to a method for producing a dental model for removable insertion in a recess of a holder, which dental model has a referencing, comprising at least one tooth part having a base to be inserted into the recess, wherein the at least one tooth part is produced using digitized data of a jaw in that the digitized data are saved in a computer beforehand and supplied to a processing machine to produce the at least one tooth part. In order to ensure simple handling of the dental model and in particular to prevent faulty insertion of the dental model or segment, according to the invention the referencing is saved in the computer and, in consideration of the referencing, the at least one tooth part is produced as having the base as a unit.

Abstract: The invention relates to a blank for producing a dental molded part such as an inlay, onlay, crown or bridge, and to a method for producing the blank. To be able to machine a dental molded part, in particular one having thin wall thicknesses, from the blank without difficulty, the blank is designed to consist of a glass ceramic having a density of between 30 and 60% of theoretical density, and of glass-ceramic powder particles with a particle size distribution d90?80 ?m, lithium silicate crystals being present in an amount of 10 to 90% by volume.
