摘要:
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.
摘要:
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.
摘要:
The invention relates to glass ceramics based on the lithium metasilicate system (Li2OSiO2(Li2SiO3)), 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.

摘要:
The invention relates to glass-ceramics based on the lithium disilicate system which can be mechanically machined easily in an intermediate step of crystallization and, after complete crystallization, represent a very strong, highly-translucent and chemically-stable glass-ceramic. Likewise, the invention relates to a method for the production of these glass-ceramics. The glass-ceramics according to the invention are used as dental material.

摘要:
A melting trough made of ceramic material is used for melting small amounts of metal by means of a flame including at least one trough channel which is not closed during operation. A thermosensor having a protective cover extends into the trough which is filled with melt during operation through an aperture in the wall of the trough. The aperture as well as the thermosensor are located below the level of the melt.
