IMPLANT MATERIAL, METHOD FOR PRODUCING THE SAME, AND METHOD FOR IMPROVING AFFINITY OF THE IMPLANT MATERIAL TO OSTEOCYTE

摘要

PROBLEM TO BE SOLVED: To provide an implant material which suppresses osteoclast induction and promotes differentiation to osteoblast.

SOLUTION: The implant material includes a substrate 10, and a carbonaceous thin film 20 formed on the surface of the substrate 10. The carbonaceous thin film 20 contains at least one selected from an oxygen-containing functional group and a nitrogen-containing functional group. The abundance ratio of the oxygen-containing functional group is not more than 4% and the ratio of the abundance ratio of the nitrogen-containing functional group to the abundance ratio of the oxygen-containing functional group is not more than 10.
