Effects of SiO
2
surface-modification on Ti-6Al-4V as dental implant materials have been studied. Prior to modification using SiO
2
, TiO
2
nanotubes were generated on the surface of Ti-6Al-4V which is expected to improve the antibacterial properties. SiO
2
/TiO
2
nanotubes were synthesized via an in-situ anodization process, employing Ti-6Al-4V as the working electrode. TEOS was used as SiO
2
precursor and the electrolyte solution used was a mixture of glycerol, NH
4
F, H
2
O, and TEOS. The amount of TEOS was varied at 1, 3 and 5 %v/v. FESEM-EDX analysis showed that SiO
2
was uniformly dispersed on modified Ti-6Al-4V surface. XRD analysis showed that the presence of SiO
2
did not significantly affect the crystallite size of TiO
2
anatase, revealing crystallite size of 29 and 28nm for TiO
2
and SiO
2
/TiO
2
nanotubes, respectively. FTIR analysis showed the presence of Ti-O-Si bond at 982cm
-1
indicating an interaction between SiO
2
and TiO
2
. Hydrophilicity of TiO
2
nanotubes were increased with SiO
2
concentration, as indicated by decreasing contact angle down to nearly 0° in the use of sufficient amount of SiO
2
on TiO
2
nanotubes. The increase of hydrophilicity due to addition of SiO
2
to TiO
2
nanotubes is expected to facilitate cell growth rate in dental implant applications.
