Effect of Gradient Nanostructured Ti on Behaviours of MG63 Cells In Vitro

Abstract EN

Titanium (Ti) is widely used in oral implants.

However, there is still a challenge to promote the osseointegration of bone tissue on the surface of Ti.

To solve this problem, we prepared novel gradient nanostructured (GNS) Ti and studied the effect of GNS on the adhesion, proliferation, and apoptosis of MG63 cells in vitro.

The results demonstrated that the GNS Ti promoted the adhesion effect and proliferation of MG63 cells better than the annealed Ti, while the ability of GNS Ti to inhibit cell apoptosis was better than that of the annealed Ti, the preliminary mechanism of which indicated by this study might be the enhanced mineralization capacity, protein adsorption ability, and hydrophilicity of the GNS Ti due to its specific nanostructure which improved the cell behaviours.

The results in this study provide the theoretical and experimental foundations for the applications of GNS Ti in dental implants and joint replacements.
