Research Abstract

Possible changes in biological potential of titanium(Ti) over time have never been addressed, with a presumption that titanium surfaces are stable in biological property, particularly osseointegration capability. The purpose of this research was to test a hypothesis that protein adsorption capacity and cell attractiveness of Ti, which are critical to the process of osseointegration, changes over time before its use. Degrading trend of protein adsorption capacity and osteoblast attractiveness of Ti surfaces during 4 weeks of storage after processing was remarkable. We postulate that immediate action needs to be taken to explore this phenomenon for possible substantial commercial, scientific and research impacts in the field.
