Abstract

A dental composition comprising a polymerizable monomer (1), initiator, filler component(s) in an amount of more than about 20 wt.-%, wt.-% with respect to the whole weight of the composition, the polymerizable monomer (1) being characterized as follows: having exactly two (meth)acrylate reactive moieties, having an unsymmetrical backbone as linkage between the (meth)acrylate reactive moieties, the two (meth)acrylate reactive moieties being attached onto the unsymmetrical monomer backbone as alkyl esters, the unsymmetrical backbone comprising one aromatic moiety of the phenolic type, the polymerizable monomer (1) not containing an acidic moiety, other atoms than carbon, hydrogen, nitrogen, and oxygen, a bisphenol moiety. The invention is also directed to the use of the dental composition as or for producing a dental filling material, dental cement, crown and bridge material, inlay, onlay, veneer, orthodontic device or dental mill blank

Description

technical field [0001] The present invention relates to a dental composition which is especially useful for restorative purposes. The composition comprises a hardenable resin matrix having a non-acidic hardenable component, a filler and an initiator and exhibits improved physical properties such as compressive strength. Background technique [0002] There are different dental filling materials that can be used for restorative purposes, including amalgam and dental composites. In order for a dental filling material to function (replace missing tooth structure), it needs to have appropriate physical properties. Specifically, they must be strong enough to be able to absorb and resist chewing forces. However, if the material is too hard, it will also become more brittle. Therefore, dental filling materials not only need to be sufficiently hard, but also need to have a certain degree of flexibility. [0003] To address these needs, commercially available dental composite fill...
