|Titanium is widely used in orthopedic and dental implant applications. In this study, a biomedical grade Titanium sheet was hydrothermally etched for improving osseointegration properties of it. The surfaces after hydrothermally etching were characterized by surface roughness, X-ray diffractometry, EDS and scannning electron spectroscopy. The proliferation properties of MC3T3 cells on etched surface was evaluated by Alamare Blue method. The surface roughness of Ti increased by hydrothermally etching and 2D structures (plate-like) were observed by SEM. EDS and GIXRD were confirmed formation of TiO2 layer with rutile structure. No significant difference between the Ti before and after etching was observed in cell proliferation assessment. This study indicates that hydrothermally etching is an effective way to modify the surface of titanium for biological applications.|
