PROBLEM TO BE SOLVED: To provide a bone restoration material having an elastic modulus close to that of a bone with PEEK as a base material, and in which the surface layer has high apatite organization properties.SOLUTION: Provided is a bone restoration material comprising: a base material made of polyether ether ketone (PEEK); and a surface layer made of titanium oxide and stuck to the prescribed part of the surface in the base material by a chemical bond via an oxycarbonyl (-O-C=O) group or the irregularity engagement of particles, and the surface layer has a zeta potential of +3 mV to +20 mV in a neutral aqueous solution. |
