▎ 摘  要

NOVELTY - A composite material is monopaste-type material comprising 25-35 wt.% organic phase comprising a polymeric matrix obtained by polymerizing mixture of dimethacrylic and urethane monomer and 75-65 wt.% inorganic phase comprising silanized mixture including lanthanum-based glass, colloidal silica, preferably zirconium-hydroxyapatite, and graphene oxide-zirconium oxide. USE - Composite material is used for dental restoration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite material, which involves preparing organic phase in which silanized inorganic phase is dispersed, and obtaining homogeneous composite paste having antibacterial property and bending strength of 110-133 MPa, from the prepared organic phase.
