Abstract

The aim of this study was to investigate the surface morphology, hydrophilicity, and effects of sandblasted and acid-etched Ti, Ti6Al4V, and Ti6Al7Nb on the bioactivity of osteoblasts. The surfaces of Ti, Ti6Al4V, and Ti6Al7Nb were treated with Al2O3 sandblasting and a hydrochloric acid–sulfuric acid mixture to create etching. Surface morphology of samples was observed using scanning electron microscopy. The size of the contact angle was measured under a microscope using a measuring instrument. Osteoblasts from Sprague-Dawley rats were inoculated onto the surfaces of Ti, Ti6Al4V, and Ti6Al7Nb at a density of 1×104cells/ml. Cell morphology was observed using scanning electron microscopy. After sandblasting and acid etching, the surfaces of Ti, Ti6Al4V, and Ti6Al7Nb presented micron-size porous morphology and were hydrophilic. Cells spread significantly on the sandblasted and acid-etched surfaces of all three surfaces. Adhesion of osteoblasts was strongest on the surface of Ti6Al7Nb. Sandblasting and acid etching promoted bioactivity on all three surfaces, although sandblasted and acid-etched Ti6Al7Nb showed better bioactivity than Ti or Ti6Al4V. Overall, osteoblasts on the surface of Ti6Al7Nb exhibited better adhesion.
