ORGANIC/INORGANIC COMPOSITE, PRODUCTION METHOD THEREOF, DENTAL MATERIAL AND BONE SUBSTITUTE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an organic/inorganic composite having high mechanical strength, in which inorganic particles are blended in a resin with high melt viscosity at high filling rate and in high dispersibility; a production method thereof; and a dental material and a bone substitute material produced therefrom.SOLUTION: This organic/inorganic composite is obtained by dispersing 60-300 pts.mass of (B) an inorganic particle mixture in 100 pts.mass of (A) a thermoplastic resin containing as a main component at least one selected from a polyarylketone resin and a polysulfone resin, where in the inorganic particle mixture, the content of particles whose particle diameter is within a range of 200-700 nm is 25 vol.% or more and the content of particles whose particle diameter is within a range of 40-100 nm is 10 vol.% or more.
