“…The proliferation of cells on the coated surface significantly covered the entire surface through pseudopods, while there are areas without cells on the uncoated titanium foam. This suggests that the coating increased the biocompatibility of the substrate (24). Roughness and high surface area provided by the nanostructured coated specimens suggest applicable states for interlocking with bone cells and enhance the bone fixation with the implant (21).…”

: The present study applied a TiO2 nanocoating on a titanium foam substrate produced by powder metallurgy through magnetron sputtering. Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD) were employed to investigate the surface morphologies of the porous specimens and pre- and post-coating phases, respectively. Also, the growth and proliferation of MG-63 cells (osteoblasts) and their attachment and proliferation on the coated porous titanium specimen (relative to the uncoated specimens) were studied using in vitro and methyl thiazol tetrazolium (MTT) cytotoxicity tests. Considering the porous macrostructure of the coated titanium specimen and the nanostructure of the TiO2 coating on the porous surface and macro-pore walls, the coated specimen was found to be effective in the biocompatibility improvement of dental and orthopedic implants.

“…For example, Mozafari et al formulated 50-125 nm ZrTiO 4 /Bioactive glass thin films via sol-gel followed by spin coating to form consecutive multi layers [155]. In a methods article by Triviño-Bolaños et al [156], sodium titanate was moulded, pressed and sintered to form porous rutile TiO 2 /Na 0.8 Ti 4 O 8 / Na 2 Ti 6 O 13 scaffolds to eliminate the use of toxic solvents often used in nanoparticle synthesis and/or to reduce costs associated with methods such as hydrothermal synthesis. Further examples of porous scaffolds (ca.…”

Improving the surface of medical implants by plasma spraying of a hydroxyapatite coating can be of critical importance to their longevity and the patient's convalescence. However, residual stresses, cracking, undesired crystallisation and delamination of the coating compromise the implants lifetime. A promising alternative surface application is an alkali-chemical treatment to generate bioactive surfaces, such as sodium and calcium titanate and their derivatives. Such surfaces obviate the need for high temperatures and resulting micro-crack formation and potentially improve the bioactive and bone integration properties through their nanoporous structures. Also, metallic ions such as silver, gallium and copper can be substituted into the titanate structure with the potential to reduce or eliminate the infections. This review examines the formation and mechanisms of bioactive/antibacterial alkaline titanate surfaces, their successes and limitations, and explores the future development of implant interfaces via multifunctional titanate surfaces on Ti-based alloys and on alternative substrate materials.
