  • METHOD FOR PRODUCING ACID-REACTIVE GLASS POWDER, ACID-REACTIVE GLASS POWDER OBTAINED BY THE PRODUCTION METHOD, AND DENTAL GLASS IONOMER CEMENT COMPOSITION CONTAINING THE SAME
    Publication number: 20240076230
    Abstract: A method for producing an acid-reactive glass powder, an acid-reactive glass powder obtained by the method, and a dental glass ionomer cement composition comprising the acid-reactive glass powder. The dental glass ionomer cement composition has good mixing property, a sufficient working time, and simultaneously can make the dental glass ionomer cement composition exhibit superior mechanical properties. More specifically, a method for producing an acid-reactive glass powder wherein an acid-reactive glass powder having a range of 2 to 10 ?m of a 50% particle size is obtainable by pulverizing a large-particle-size acid-reactive glass powder having a range of 250 to 3000 ?m of a 50% particle size in a state where a small-particle-size acid-reactive glass powder having a range of 1 to 5 ?m of a 50% particle size coexists.
