Hardening calcium phosphate composition for bone tissue repair, bone repair material and various dental materials

摘要

The present invention provides a curable calcium phosphate composition for biological hard tissue repair that provides a cured product having excellent durability in a moist environment such as the body or the oral cavity. The present invention is a curable calcium phosphate composition for biological hard tissue repair comprising tetracalcium phosphate particles (A), calcium hydrogen phosphate particles (B), calcium carbonate particles (C), and water (D), The tetracalcium phosphate particles (A) are added in an amount of 5 to 75 weights with respect to a total of 100 parts by weight of the tetracalcium phosphate particles (A), the calcium hydrogen phosphate particles (B), and the calcium carbonate particles (C). Part, 10 to 70 parts by weight of the calcium hydrogen phosphate particles (B), and 2 to 50 parts by weight of the calcium carbonate particles (C).
