| Abstract Scope |
Ti-6Al-4V and hydroxyapatite (HA) are often used for the fabrication of dental and orthopedic implants. Ti-6Al-4V is used for its superior high fracture and corrosion resistance properties, while HA on the other hand is most suitable for coating. However, despite the attractive properties of Ti-6Al-4V, surface modification is needed to enhance its biointegration to bone. This study proposes an easy and reproducible method of enhancing osseointegration by the coating of HA onto Ti-6Al-4V. The resulting Ti-6Al-4V/HA system is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and Atomic Force Microscopy (AFM). The results show that nanostructured HA rods can be produced on the Ti-6Al-4V substrate. The nanorods are shown to affect the cell proliferation and adhesion of cells onto HA-coated Ti-6Al-4V substrates. The implications of the results are discussed for the potential applications of HA coated Ti-6Al-4V in dental and orthopedic applications. |
