Outline of Final Research Achievements |
The research project developped a new surface treatment process for fabricating Ag-contained hydroxyapatite layer on titanium implant and demonstrated that the new process enables to reduce the risks for surgical operation of artificial joint replacement. The coating fabricated by the new process is expected to have high-adhesive strength and furthermore, facilitatie osteogenesis around the implant. In addition, the coated-implant showed an excellent antibacterial efficcacy due to Ag-release from the coating although the release did not show cytotoxicity. The research project demonstrate that the new surface modification process can provide a high-performance titanium medical implant with a low cost.
