Hydroxyapatite formation on alkali-treated titanium with different content of Na+ in the surface layer.

abstract：:The early biological response at titanium (Ti), copper (Cu)-coated Ti and sham sites was evaluated in an in vivo rat model. Material surface chemical and topographical properties were characterized using Auger electron spectroscopy, energy dispersive X-ray spectroscopy and interferometry, respectively. The number of l...
