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
一种牙科组合物,包括可聚合单体(1),引发剂,填充剂组分,其重量百分比超过整个组合物的约20%,其中可聚合单体(1)具有以下特征:恰好有两个(甲基)丙烯酸酯反应基团,具有不对称的骨架作为(甲基)丙烯酸酯反应基团之间的连接,两个(甲基)丙烯酸酯反应基团作为烷基酯附着在不对称单体骨架上,不对称骨架包含苯酚类型的芳香基团,可聚合单体(1)不含有酸性基团,除碳、氢、氮和氧之外的其他原子,双酚基团。本发明还涉及将该牙科组合物用作或用于制备牙齿充填材料、牙科水泥、冠桥材料、内镶、外镶、瓷贴面、正畸装置或牙科铣刀毛坯。
