Abstract
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.
Claims20
A dental curable composition comprising:
- 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 tartaric acid (D) is L-tartaric acid,
- wherein
- the dental curable composition comprises from 70 to 99 parts by weight of the fluoroaluminosilicate glass particles (A), from 1 to 30 parts by weight in total of the basic calcium phosphate particles (B1) and the acidic calcium phosphate particles (B2), from 10 to 40 parts by weight of the polyalkenic acid (C), from 0.3 to 10 parts by weight of the tartaric acid (D), and from 10 to 90 parts by weight of the water (E) each relative to 100 parts by weight in total of the fluoroaluminosilicate glass particles (A), the basic calcium phosphate particles (B1), and the acidic calcium phosphate particles (B2), and a Ca/P ratio of a sum of the basic calcium phosphate particles (B1) and the acidic calcium phosphate particles (B2) is from 1.10 to 1.95.
A dental curable composition kit comprising:
- a powder agent (X) comprising at least fluoroaluminosilicate glass particles (A), basic calcium phosphate particles (B1), and acidic calcium phosphate particles (B2), and
