Surface characteristics and osteoblastic cell response to titanium-8tantalum-3neobium alloy

摘要

In the present study, the surface properties and osteblastic responses to a titanium-8%tantalum-3%niobium (Ti-8Ta-3Nb) alloy were investigated in vitro. The surface roughness and morphology of all samples appeared similar. The surface of the Ti-8Ta-3Nb alloy was more hydrophilic than those of commercially pure titanium (Ti-S) and Ti-6Al-4V alloy. The Ti-8Ta-3Nb alloy had a better cellular response with regard to proliferation and ALP activity. The present study showed improved surface characteristics and osteoblastic response to the Ti-8Ta-3Nb alloy compared to Ti-S and Ti-6Al-4V alloy.
