The present invention is directed to polymerizable dental compositions containing (a) 3 to 80 wt. % of cycloaliphatic epoxides; b) 0 to 80 wt. % of an epoxide or a mixture of epoxides which are different from a); c) 3 to 85 wt. % of a filler material; d) 0.01 to 25 wt. % of initiators, inhibitors and/or accelerators; e) 0 to 25 wt. % of auxiliary agents, the individual percentages of which are in relation to the total weight. The new polymerizable agents are particularly suited as dental material.

Polymerizable compositions based on epoxides

The invention relates to preparations with improved curing behavior, which are characterized in that they contain 0.0005 to 50 wt. % of soluble and/or fine-particle organic and/or inorganic alkaline earth and/or alkali metal compounds. The preparations according to the invention may be used for bonding, sealing, casting and coating substrates, also in medical dental and technical dental preparations, and for making impressions of articles and, more particularly, for making dental impressions.

Storage-stable cationcally polymerized preparations with improved hardening characteristics

Hardenable mass with silane dendrimers

The present invention is directed to polymerizable dental compositions containing a) 3 to 80 wt. % of cycloaliphatic epoxides; b) 0 to 80 wt. % of an epoxide or a mixture of epoxides which are different from a); c) 3 to 85 wt. % of a filer material; d) 0.01 to 25 wt. % of initiators, inhibitors and/or accelerators; e) 0 to 25 wt. % of auxiliary agents, the individual percentages of which are in relation to the total weight. The new polymerizable agents are particularly suited as dental material.

The invention relates to impression compositions based on vulcanizable pother materials, which are characterized in that the ready-mixed pastes comprise

Impression compositions comprising triglycerides

Dental compositions based on an bifunctional or polyfunctional acrylic-acid and/or methacrylic-acid esters, which contain an initiator system for radical polymerization and which additionally contain a compound of the general formula ##STR1## in which: Ar represents aryl or substituted aryl,

Dental compositions comprising bifunctional or polyfunctional

Hydrophilated dental impression compounds

Dental compositions based on an at least bifunctional or polyfunctional acrylic-acid and/or methacrylic-acid esters, which contain an initiator system for radical polymerization and which additionally contain a compound of the general formula ##STR1## in which: Ar represents aryl or substituted aryl,

A polyether-impression material comprising components

Polyether-impression material and method for its preparation and use

Polymerizable compositions are described on the basis of (meth)acrylic acid esters which contain as filler a precipitation polymer that is formed from acrylic acid esters and/or methacrylic acid esters, and possibly other copolymerizable monomers, with 10 to 100 mol % of the (meth)acrylic acid esters being bi or polyfunctional. These compositions are particularly suitable as dental compositions.

Polymerizable compositions, process for the preparation thereof, and use

An ionogenic compound, soluble or dispersible in aziridine compounds is utilized for delaying the polymerization of aziridine compounds initiated by a sulfonium salt. Said ionogenic compounds contain an anion which is more nucleophilic than the anion present in the sulfonium salt employed. Moreover, a preparation for dental purposes is described which contains these components.
