Abstract: [Problem]
To support the metal without segregation on the zirconia mill blank for dental cutting and machining which has been adjusted to a hardness that enables to cut and machine by calcining at a low temperature.
[Solution]
A zirconia mill blank for dental cutting and machining is prepared by A preparing method of a zirconia mill blank for dental cutting and machining, comprising an impregnation step of impregnating a porous zirconia molded body with an impregnating solution containing at least one metal ion and at least one precipitant, and a deposition step of decomposing the precipitant in the porous zirconia molded body to deposit a metal compound.

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.

Abstract: Provided is a curable composition comprising a polymerizable monomer (A); spherical particles (B) having an average primary-particle diameter in a range of 230 nm to 1,000 nm; and a polymerization initiator (C), in which 90% or more of individual particles constituting the spherical particles (B) lies in a range of ±5% based on the average primary-particle diameter, and the refractive index of the spherical particles (B) is larger than the refractive index of a polymer of the polymerizable monomer (A). When a 1 mm-thick cured product is formed from the curable composition and the Y value (Yb) of the colored light of the cured product on a black background and the Y value (Yw) of the colored light of the cured product on a white background are each measured using a color difference meter, the ratio therebetween, Yb/Yw, being within a range of 0.2 to 0.5.

Abstract: Delivery and/or injection systems, preferably for medical applications. Especially, a kit of parts for providing a dental composition able to self-hardening. The kit of parts includes a first waterproof container including an anhydrous calcium silicate phase; and a second container including an aqueous phase. The kit of parts may be used in delivery and/or injection systems so that it delivers a homogenous calcium silicate-based composition having a volume ratio between the calcium silicate phase and the aqueous phase ranging from 1 to 3. Also, the hardened material obtained from the kits of parts, the delivery and/or injection system.
