Title:
METHOD FOR PREPARING DENTAL COMPOSITE RESIN MATERIAL, AND PRODUCT PREPARED USING DENTAL COMPOSITE RESIN MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/219742
Kind Code:
A1
Abstract:
A method for preparing dental composite resin material, and a product prepared using dental composite resin materialThe method comprises: (1) weighing feedstocks, the feedstocks comprising ethylenically unsaturated monomers, enhanced fibers, a filler, an initiator, a polymerization inhibitor, and a colorant; (2) mixing all the weighed feedstocks other than the enhanced fibers to obtain a composite resin monomer precursor; (3) impregnating the weighed enhanced fibers in the composite resin monomer precursor for 1-5 hours, the impregnation pressure being small than or equal to 0.1 MPa, to obtain composite resin monomer precursor-adsorbed enhanced fibers; and (4) curing the composite resin monomer precursor-adsorbed enhanced fibers to obtain a dental composite resin material. The dental composite resin material has crossbreaking strength greater than 600 MPa and light transmittance greater than 40%.
