Title:
CURABLE CALCIUM PHOSPHATE COMPOSITION FOR IN VIVO HARD TISSUE REPAIR, BONE REPAIR MATERIAL, AND VARIOUS DENTAL MATERIALS
Document Type and Number:
WIPO Patent Application WO/2015/019600
Kind Code:
A1
Abstract:
The present invention provides a curable calcium phosphate composition that is for in vivo hard tissue repair and results in a cured body having superior durability in moist environments such as the oral cavity or in the body. The curable calcium phosphate composition for in vivo hard tissue repair contains tetracalcium phosphate particles (A), calcium hydrogenphosphate particles (B), calcium carbonate particles (C), and water (D), wherein with respect to a total of 100 parts by weight of the tetracalcium phosphate particles (A), calcium hydrogenphosphate particles (B), and calcium carbonate particles (C), there are 5-75 parts by weight of the tetracalcium phosphate particles (A), 10-70 parts by weight of the calcium hydrogenphosphate particles (B), and 2-50 parts by weight of the calcium carbonate particles (C).
