DENTAL CURABLE COMPOSITION, AND METHOD FOR PRODUCING SAME

摘要

A dental curable composition containing fluoroaluminosilicate glass particles (A), basic calcium phosphate particles (B1), acidic calcium phosphate particles (B2), a polyalkenic acid (C), tartaric acid (D), and water (E), wherein the dental curable composition contains 70 to 99 parts by weight of (A), 1 to 30 parts by weight in total of (B1) and (B2), 10 to 40 parts by weight of (C), 0.3 to 10 parts by weight of (D), and 10 to 90 parts by weight of (E) each relative to 100 parts by weight in total of (A), (B1), and (B2), and a Ca/P ratio of a sum of (B1) and (B2) is from 1.10 to 1.95. Accordingly, provided is a dental curable composition that is high in mechanical strength, particularly compressive strength, and excellent in remineralization capability.
