Abstract
Considering the wide range of applications of titanium in prosthesis, the latest investigations have been focused on the surface properties of this metal. Thus, chemical surface modification of titanium implants can be used to improve Bone-to-implant contact, peri-implant bone growth and higher adhesion strength. In this study, the surface topography of polished titanium surfaces treated with mixed solution of three acids containing hydrochloric acid (HCl)- hydrofluoric acid (HF)- phosphoric acid (H3PO4) were studied. Also, in order to investigate titanium surfaces, SEM, AFM analyses were carried out. The results revealed that acid concentrations variation in the aforementioned mixed solution of three acids, had a significant effect on the morphology and surface roughness, and the greatest R.M.S and Ra was attributed to 80%HCl- 10% HF- 10% H3PO4.
