Title:
Dentistry restoration material
Document Type and Number:
Japanese Patent JP6084372
Kind Code:
B2
Abstract:
A dental restorative composition is provided that includes a polymerizable resin, a substantially translucent structural filler, a nanofiller having a mean particle size less than 100 nm, and at least one rheology-modifying additive. In one embodiment, the structural filler has a refractive index substantially similar to that of the polymerizable resin, a coarse particle fraction, and a fine particle fraction having a mean particle size greater than 0.1 µm and smaller than the mean particle size of the course particle fraction. The relative ratio of the coarse particle fraction to the fine particle fraction is in the range from 12:1 to 2:1 by volume, the particle size distribution of each fraction is essentially monomodal, and the D(90) of the fine particle fraction is less than or equal to the D(10) of the course particle fraction.
