Presently described are dental compositions comprising one or more fatty mono(meth)acrylates, methods of use, dental articles, and methods of making dental compositions. It has been found that a relatively low concentration of a fatty mono(meth)acrylate can improve the handling characteristics of a dental composition by reducing the tendency of the composition to stick to a dental instrument and/or by reducing the tendency of a dental composition to string when being manipulated by a dental instrument. In one embodiment, a hardenable dental composition is described comprising a polymerizable resin composition comprising at least one multifunctional ethylenically unsaturated monomer; 0.2 to 10 wt-% of one or more fatty mono(meth)acrylate monomers; and at least 50 wt-% of inorganic oxide filler.
目前描述的是包含一种或多种脂肪单(甲基)丙烯酸酯的牙科组合物、使用方法、牙科用品和牙科组合物的制造方法。研究发现,相对低浓度的脂肪单(甲基)丙烯酸酯可以改善牙科组合物的操作特性,降低组合物粘附在牙科器械上的倾向和/或降低牙科组合物在牙科器械操作时串连的倾向。在一个实施方案中,描述了一种可硬化牙科组合物,该组合物包含一种可聚合树脂组合物,该树脂组合物包含至少一种多功能乙烯基不饱和单体;0.2-10 wt-%的一种或多种脂肪单(甲基)丙烯酸酯单体;以及至少 50 wt-%的无机氧化物填料。
