A process for the preparation of multi-coloured dental restorations is described, in which glasses and glass ceramics with various compositions are given the shapes of dental restorations and colour changes are effected in the glasses and glass ceramics by irradiating them with artificial electromagnetic radiation and subjecting them to a heat treatment.

Method for manufacturing a multi-color dental restoration

Glass ceramics having SiOas main crystal phase and precursors thereof are described which are characterized by very good mechanical and optical properties and in particular can be used as restoration material in dentistry.

Glass ceramic having SiOas main crystal phase

The invention relates to glass ceramics and glasses with a europium content, containing the following components: and which are suitable in particular for the production of dental restorations, the fluorescence properties of which largely correspond to those of natural teeth.

Fluorescent glass ceramics and glasses with europium content

The invention relates to glass ceramics and glasses with cerium and tin content, which comprise the following components: and which are suitable in particular for the preparation of dental restorations, the fluorescence properties of which largely correspond to those of natural teeth.

Fluorescent glass ceramics and glasses with cerium and tin content

The invention relates to glass ceramics and glasses with a europium content, containing the following components: and which are suitable in particular for the production of restorations, the fluorescence properties of which largely correspond to those of natural teeth.

Lithium silicate-low quartz glass ceramics are described which are characterized by a combination of very good mechanical and optical properties and can therefore be used in particular as restoration material in dentistry.

Lithium silicate-low quartz glass ceramic

Glass ceramic having SiO2 as main crystal phase

Quartz solid solution glass ceramics and precursors thereof are described, which are characterized by very good mechanical and optical properties and in particular can be used as restoration material in dentistry.

Glass ceramic having a quartz solid solution phase

The invention relates to a lithium silicate glass ceramic which contains lithium silicate as main crystal phase and scheelite and/or powellite as further crystal phases. The invention also relates to a corresponding starting glass, a starting glass with nuclei, a process for producing the glass ceramic and the starting glasses as well as the use thereof.

Lithium silicate glass ceramic with scheelite or powellite crystal phase

Lithium silicate-wollastonite glass ceramics are described which are characterized by a controllable translucence and can be easily machined and therefore can be used in particular as restoration material in dentistry.

Lithium silicate-wollastonite glass ceramic

Lithium silicate-diopside glass ceramics are described which are characterized by a controllable translucence and can be satisfactorily processed mechanically and therefore can be used in particular as restoration material in dentistry.

Lithium silicate diopside glass ceramics

Glass ceramic with SiO2 as the main crystalline phase

The invention relates to the use of lithium silicate glass ceramics and glasses with rubidium oxide content for coating an oxide ceramic, a metal or an alloy.

Lithium silicate glass ceramic and glass with rubidium oxide content

The invention relates to the use of lithium silicate glass ceramics and glasses with caesium oxide content, which are suitable in particular for veneering oxide ceramic restorations and metal restorations.
