Document Type and Number:
WIPO Patent Application WO/2021/131476
Kind Code:
A1
Abstract:
Provided is a curable composition that is for dentistry and that contains: a polymerizable monomer (A); an inorganic filler (B) having an average particle size of 0.1-1 μm; an organic-inorganic composite filler (C) having an aggregate structure in which inorganic primary particles having an average particle size of 10-1000 nm are bonded together through a resin layer covering the surface of the particles, to form a void having a specific pore volume; and a polymerization initiator (D). In the organic-inorganic composite filler (C), a curved surface-shaped organic-inorganic composite filler (C1) formed of organic-inorganic composite aggregate particles having a curved surface shape, and an amorphous organic-inorganic composite filler (C2) formed of amorphous organic-inorganic composite aggregate particles having an edge portion, are mixed such that C1/(C1+C2) equals 0.2-0.8 in terms of the number of particles having a particle size of 5 μm or more.
