It was recently reported that implant osseointegration is affected by surface wettability. The relationship between hydrophilicity and cell adhesion was corroborated by numerous in vivo studies. Concentrated alkali improves the biocompatibility of pure titanium.
No structural change was confirmed by Scanning electron microscope (SEM) or scanning probe microscopy (SPM) observation. X-ray photoelectron spectroscopy (XPS) analysis presented with hydroxide formation and a reduction in the C peak. A decrease in
The present study clarified that low-temperature, atmospheric-pressure plasma treatment imparts hydrophilicity to the surface of pure titanium metal and removes contaminants from it. The results also disclosed that plasma treatment induces the initial adhesion of rat bone marrow cells and proteins to the material surface and may trigger hard tissue formation. It is expected that this technology will be extensively applied in clinical settings because it is compact and easy to use.
