Abstract
Whether silicate-substituted strontium apatite (SrSiP) stimulates osteogenesis on the surface of implants has been evaluated in the present study. Polyether ether ketone (PEEK) disks were coated with a nanocrystalline SrSiP dispersion using CO2 laser irradiation. At approximately 300°C, the coating layer of SrSiP was tightly adhered to the surface of PEEK disks. The SrSiP-coated PEEK showed excellent bioactive properties when bone marrow-derived mesenchymal stem cells were cultured on the PEEK disks, when compared to the untreated PEEK disks.
