Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools and which subsequently can be converted into lithium silicate products showing high strength.

Lithium silicate materials

Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools.

The present invention is directed to a porous pre-densified CeO-stabilized ZrOceramic having a density of 50.0 to 95.0%, relative to the theoretical density of zirconia, and an open porosity of 5 to 50% as well as to a densified CeO-stabilized ZrOceramic having a density of 97.0 to 100.0%, relative to the theoretical density of zirconia, and wherein the grains of the ceramic have an average grain size of 50 to 1000 nm, methods for the preparation of the pre-densified and densified ceramics and their use for the manufacture of dental restorations.

CeO2-stabilized ZrO2 ceramics for dental applications

A composition, containing a carrier medium and particles based on a metal compound with a weight-average particle diameter of 1 nm to 10 &#x3bc;m is useful to clean metal or ceramic surfaces which are part of a dental restoration or of an implant abutment.

Compositions containing cleaning particles
