| Outline of Final Research Achievements |
Various coating methods have been attempted to improve the biological properties of PEEK materials. Among them, it is shown that surface modification with titanium nanostructures on the PEEK surface increases hydrophilicity and promotes early cell adhesion and induction of hard tissue differentiation.However, the biocompatibility of this material is not clear.Therefore, in this study, we investigated how the nanostructure treatment of pure titanium metal-deposited PEEK material affects the behavior of rat bone marrow cells. As a result, the pure titanium metal was coated by plasma treatment to precipitate nanostructures. Part of the possibility that the surface of PEEK material exhibits high ability to induce hard tissue differentiation was shown.
