Abstract

Grit blasting using bioactive HA and biodegradable CMP followed by acid etching has been done. HNO₃ and H₃PO₄ were used for the etching solution by controlling the concentration and etching time to know the effect on the surface chemistry and morphology of the Ti implant. Characterization of samples was done by using SEM, EDX and surface profilometer. The contents of residues on Ti surface decreased with increasing acid concentration and etching time. It was observed that the acidic etching rate of HA grits on Ti surface was faster than that of CMP grits. And HNO₃ etched more rapidly the HA and CMP grits on Ti surface, compared to H ₃PO₄. Therefore, the surface roughness of dental implants can be controlled by having appropriate combination of acid concentration and etching time.
