Evidence construction of a new titanium material concept, and research of the recovery method

钛（Ti）生物学潜能随时间的可能变化从未得到解决，假设钛表面的生物学特性稳定，特别是骨整合能力。本研究的目的是检验一个假设，即钛的蛋白质吸附能力和细胞吸引力（对骨整合过程至关重要）在使用前随时间变化。钛表面蛋白质吸附能力和成骨细胞吸引力在处理后的4周内有明显的下降趋势。我们认为，需要立即采取行动，探讨这一现象在该领域可能产生的重大商业、科学和研究影响。

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.
