Abstract

Introduction: Dental implants were widely used being considered as successful treatment option for replacing missing teeth. Different methods were used to alter surface morphology and topography to accelerate healing and improve oseointegration. The aim of this study was to assess corrosion resistance and in vitro bioactivity in simulated body fluid (SBF) of plasma nitrided surfaces with and without hydroxyapatite coating.

Material and Methods: Commercial pure titanium grade II surfaces were treated using glow plasma nitride apparatus for 10 h, then coated with hydroxyapatite by dip coating, The electrochemical corrosion test was performed once the samples were inserted in Hank’s solution, the polarization potential and corrosion rate were measured. Treated and coated samples immersed in SBF for 7 days to evaluate the in vitro bioactivity. Phase analysis by X-ray diffraction (XRD) and scanning electron microscope (SEM) have been carried out on the surfaces before and after immersion in SBF.

Results: Coating with hydroxyapatite on pre-nitrided titanium surfaces increases the bioactivity of titanium and increases the corrosion resistance compared to nitrided and untreated surfaces.

Conclusion: Coating on pre-nitrided surfaces can be considered an effective way to enhance the formation of bone-like material on titanium surfaces and increase the corrosion resistance of titanium.
