摘要： Provided are : an organic/inorganic composite having inorganic particles blended in a resin having a high melt viscosity at a high filling rate and with high dispersibility, the organic/inorganic composite having high mechanical strength, and a manufacturing method therefor; and a dental material and bone substitute material manufactured using the organic/inorganic composite. The organic/inorganic composite includes: (A) 100 parts by mass of a thermoplastic resin containing as a main component at least one kind selected from a polyarylketone resin and a polysulfone resin; and (B) 60 to 300 parts by mass of an inorganic particle mixture dispersed in the thermoplastic resin, in which the inorganic particle mixture contains inorganic particles each having a particle diameter of from 200 to 700 nm at a content of 25 vol% or more, and inorganic particles each having a particle diameter of from 40 to 100 nm at a content of 10 vol% or more.

摘要： Provided is a resin composite that is excellent in abrasion resistance and has high fracture energy as compared to a related-art resin composite. Specifically, provided are: a resin composite, which is produced using: 100 parts by mass of a resin having a melting point or fluidization temperature of from 200 to 500°C; and 40 to 400 parts by mass of inorganic particles surface-treated with a surface treatment agent having a reactive double bond group or an aromatic group at an end thereof, the resin composite having an average embedding rate, which is represented by the following equation (1), of 55% or more; a manufacturing method for the resin composite; and a dental material using the resin composite: ·Equation (1) Average embedding rate (%)=100×{EP/(EP+V)} (in the equation (1) : EP represents the number {particles/(10 µm×10 µm)} of the inorganic particles per square region measuring 10 µm on each side exposed in a polished surface of a test piece of the resin composite in a case where the polished surface is observed with an SEM; and V represents the number {voids/(10 µm×10 µm)} of voids per square region measuring 10 µm on each side formed through elimination of the inorganic particles in the square region measuring 10 µm on each side where the EP number is counted.
