Abstract
The major disadvantage of titanium dental implants is their bio-inertness, which could be alleviated using surface treatment techniques. Oxidation using hydrogen peroxide (H2O2) was used for surface treatment of titanium dental implants in this study. The effect of some oxidizing ions such as Cl and F in addition to post-heat treatment was investigated using X-ray diffractometry (XRD), Raman spectroscopy, Field Emission-Scanning Electron Microscopy (FESEM) and wettability assessment. The results of the study indicated that the different ions did not change phases on the surface of titanium implants however, they affected the morphology, thickness and wettability of treated titanium implants surface. The maximum thickness of anatase including macro cracks was formed on the surface of H2O2 treated titanium while maximum wettability was obtained on the surface of H2O2 + Cl treated titanium implant, and fluoride ion inhibit anatase formation on the surface of H2O2 treated titanium implant.
