    • 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.
    • 目前描述的是含有一种或多种脂肪单(甲基)丙烯酸酯,使用方法,牙科用品和制造牙科用组合物的方法的牙科用组合物。 已经发现,相对低浓度的脂肪单(甲基)丙烯酸酯可以通过降低组合物粘附到牙科器械上的趋势和/或通过降低牙科组合物的趋势来改善牙科用组合物的处理特性 当由牙科仪器操纵时进行弦线。 在一个实施方案中,描述了一种可硬化的牙科用组合物,其包含包含至少一种多官能烯属不饱和单体的可聚合树脂组合物; 0.2〜10重量%的一种或多种脂肪单(甲基)丙烯酸酯单体; 和至少50重量%的无机氧化物填料。
