摘要:
Dental material based on polymerizable (for example ethylenically unsaturated) monomers, epoxides, ormocers, liquid crystal monomers, oxethanes, spiro-orthoesters or spiro-carbonates as binders, a catalyst for cold, hot and/or photo-polymerization, and fillers, and a process for its preparation. Porous glass ceramics, a process for their preparation and uses thereof are also described. Dental materials according to the invention are suitable as alternative materials to the use of amalgam fillings.

摘要:
In dental ceramics containing zirconium dioxide and sili-con-dioxide with a Zr/Si ratio of between 0.5 and 1.0, 1 to 12 wt % of aluminum oxide and up to 2 wt % of an alkali - or earth alkali metal oxide, those materials are selectively mixed with yttrium-stabilized zirconium dioxide with a Zr/Si ratio of the mixture being between 0.5 and 1 wt % and also a silicon organic compound as well as a compression aid, and a green body is formed from the mixture by milling, which green body is then sintered.

摘要:
The invention proposes to produce a mixture that is shrink-resistant, or has a freely selectable degree of shrinkage, and can be used as a molding compound, and a method for producing a corresponding oxide-ceramic sintered body. The molding compound comprises an intermetallic compound and a wax. In the method for producing an oxide-ceramic sintered body, a green body is molded from a molding compound of this type, dewaxed and sintered in an oxidizing atmosphere to form a ceramic sintered body. The molding compound is suited for producing dentures and dental fillings.
摘要:
Dental composites containing hybrid fillers and process for their production. Dental compounds are disclosed which contain two- or multi-phase inorganic fillers in an organic polymer matrix. These are characterized by improved abrasion resistance.
