Potassium-zinc-silicate glasses are described which because of their high chemical stability as well as their optical properties and favorable working properties are suitable in particular as coating or veneering materials for ceramic dental suprastructures and thus for the preparation of all-ceramic dental restorations, such as crowns or bridges.

Low-temperature-sintering potassium-zinc-silicate glass

A low-temperature-sintering apatite glass ceramic is described which is characterized by a high chemical stability, a low coefficient of expansion as well as high translucency and which is particularly suitable on its own or together with glasses or other glass ceramics as coating or veneering material for ceramic dental restorations.

Low temperature-sintering apatite glass ceramic

A process is described for the preparation of shaped translucent lithium disilicate glass ceramic products which are characterized by high strength and good chemical stability and may be processed by pressing in the plastic state or milling to finished glass ceramic products which may be used in particular as dental restorations.

Process for the preparation of shaped translucent lithium disilicate glass ceramic products

A composite material is described which contains polymerizable monomers plus a special transparent glass having high release of calcium ions and fluorine ions and, because of this release property and in particular of its optical properties, can be used as a restoration material in dentistry.

Polymerizable composite material

Alkali silicate glasses are described which, in view of their good chemical stability and their optical properties and processing properties, are particularly suitable as a coating or veneering material for ceramic dental frameworks and hence for the production of all-ceramic dental restorations such as crowns or bridges.

Alkali silicate glass

An apatite glass ceramic is described which is characterized by good chemical stability, a low expansion coefficient and high translucence, and is particularly suitable, by itself or together with glasses or other glass ceramics, as a veneering material for ceramic dental restorations.
