Patent ID: 8765837

Claim:
A dental curable composition including: (A) a polymerizable monomer component containing an acidic group-containing polymerizable monomer; (B) water; and (C) a chemical polymerization initiator component comprising a radical-generating species and a reactive species that generates radicals upon reacting with the radical-generating species; wherein, said dental curable composition is stored being divided into a plurality of packages, and is polymerized and cured by mixing together components contained in the packages; and wherein, one package (I) among said packages contains said component (A) and said component (B), and, further, contains polyvalent metal ions in an amount of 0.3 to 10 meq per gram of the polymerizable monomer component (A) contained in said package, wherein the acidic group-containing polymerizable monomer is conically crosslinked; said polyvalent metal ions is at least one selected from the group consisting of aluminum ions, lanthanum ions, and titanium ions; and said chemical polymerization initiator (C) is stored being divided into at least two packages so that the radical-generating species and the reactive species do not come in contact with each other.
