The invention relates to a method of manufacturing a ceramic molding, comprising the following steps: a) providing three or more ceramic powder layers that are arranged in layers, one on top of the other, to form a compression-molded element and sintering the compression-molded element obtained in step b) to form a ceramic molding, characterized in that the ceramic powder layers have different compositions, each ceramic powder layer comprising a mixture of at least two different base powders and each base powder containing at least 80 wt. % ZrOand at least 0.02 wt. % AlO, each weight amount being relative to the total weight of the constituents of the base powder.

Method of manufacturing a zirconium dioxide green body with color and translucency gradients

The present invention relates to a process for producing a workpiece made of glass ceramics, and to the workpiece obtainable by the process according to the invention. Further, the invention relates to the use of the workpiece obtained as a dental restoration, and to a process allowing the translucency of a workpiece to be controlled.

Process for producing a workpiece with low translucency

The invention relates to glass ceramics based on the lithium metasilicate system (LiO.SiO(LiSiO)), which are mechanically processible in a simple manner in an intermediate stage of the crystallization and, after complete crystallization, represent a high-strength, highly translucent and chemically stable glass ceramic.

Lithium silicate glasses or glass ceramics, method for production thereof and use thereof

The invention refers to a method for producing a dental restoration comprising a lithium silicate glass or glass ceramic as well as a dental restoration inself. The invention further refers to a ingot with the same composition having a defined strength.

Dental restoration, method for its production and ingot

The invention relates to glass ceramics, which show high strength, high translucency, high chemical stability and which are still mechanically processible. The invention further refers to a method for producing a dental restoration comprising such glass or glass ceramic as well as the dental restoration itself.

Dental restoration, method for production thereof and glass ceramic

The invention relates to glass ceramics based on the lithium metasilicate system (LiOSiO(LiSiO)), which are mechanically processible in a simple manner in an intermediate stage of the crystallization and, after complete crystallization, represent a high-strength, highly translucent and chemically stable glass ceramic.
