Abstract
Official abstract text for this publication.
According to one aspect of the present invention, a dental curable composition includes: polymerizable monomers; inorganic particles (A1) and/or inorganic particles (A2) (excluding the inorganic particles (A2); and inorganic particles (B). The inorganic particles (A1) are surface-treated with a compound expressed by a general formula (1) and have a volume-median particle size of greater than or equal to 0.1 μm and less than or equal to 0.9 μm. The inorganic particles (A2) are surface-treated with a compound expressed by a general formula (2) and have a volume-median particle size of greater than or equal to 0.1 μm and less than or equal to 0.9 μm. The inorganic particles (B) are particles where a group expressed by a general formula (A) is present at surfaces, are particles where a group expressed by a general formula (B) is present at surfaces, and/or are particles surface-treated with a compound expressed by a general formula (3) and have an average primary particle size of greater than or equal to 5 nm and less than or equal to 50 nm. A ratio of a mass of the inorganic particles (B) to a total mass of the inorganic particles (A1), the inorganic particles (A2), and the inorganic particles (B) is greater than or equal to 0.001 and less than or equal to 0.015.

1 . A dental curable composition comprising: polymerizable monomers; inorganic particles (A1) and/or inorganic particles (A2) (excluding the inorganic particles (A2); and inorganic particles (B), wherein the inorganic particles (A1) are surface-treated with a compound expressed by a general formula (in the formula, R 1 is a hydrogen atom or a methyl group, R 2 is a hydrolyzable group, R 3 is a hydrocarbon group having 1 to 6 carbon atoms, p is 2 or 3, and q is an integer greater than or equal to 6 and less than or equal to 13), and the inorganic particles (A1) have a volume-median particle size of greater than or equal to 0.1 μm and less than or equal to 0.9 μm, wherein the inorganic particles (A2) are surface-treated with a compound expressed by a general formula (in the formula, R 1 is a hydrogen atom or a methyl group, R 2 is a hydrolyzable group, R 3 is a hydrocarbon group having 1 to 6 carbon atoms, p is 2 or 3, and q is an integer greater than or equal to 1 and less than or equal to 5), and the inorganic particles (A2) have a volume-median particle size of greater than or equal to 0.1 μm and less than or equal to 0.9 μm, wherein the inorganic particles (B) are particles where a group expressed by a following general formula (in the formula, R 4 and R 5 are independently a methyl group or an ethyl group) is present at surfaces, are particles where a group expressed by a following general formula (in the formula R 6 , R 7 , and R 8 are independently a methyl group or an ethyl group) is present at surfaces, and/or are particles surface-treated with a compound expressed by a general formula (in the formula R 1 is a hydrogen atom or a methyl group, R 2 is a hydrolyzable group, R 3 is a hydrocarbon group having 1 to 6 carbon atoms, p is 2 or 3, and q is an integer greater than or equal to 1 and less than or equal to 6), and the inorganic particles (B) have an average primary particle size of greater than or equal to 5 nm and less than or equal to 50 nm, and wherein a ratio of a mass of the inorganic particles (B) to a total mass of the inorganic particles (A1), the inorganic particles (A2), and the inorganic particles (B) is greater than or equal to 0.001 and less than or equal to 0.015. 2 . The dental curable composition as claimed in claim 1 , wherein a ratio of a mass of the inorganic particles (A1) to the total mass of the inorganic particles (A1), the inorganic particles (A2), and the inorganic particles (B) is greater than or equal to 0.2. 3 . The dental curable composition as claimed in claim 1 , wherein the dental curable composition is a flowable composite resin.
