“…We have previously reported that despite differences in surface topography, early cellular response was similar for both sandblasted cpTi plates and those etched in concentrated H2SO4 26) . In the same vein, there were some studies which reported that there were no clear effects of surface roughness on proliferation of bone cells [27][28][29] . However, other studies reported a significant correlation between surface roughness and cell growth, whereby greater proliferation of osteoblasts on smoother or rougher surfaces resulted in better ossteointegration [30][31][32][33][34] .…”

The purpose of this study was to evaluate the effects of acid-etched titanium on the biological responses of osteoblast-like MC3T3-E1 cells. Four types of treatments (polishing, sandblasting, concentrated H2SO4 etching, and concentrated H2SO4 etching with vacuum firing) were carried out on the surfaces of commercially pure titanium (cpTi) disks. MC3T3-E1 cells were then cultured on the treated cpTi surfaces. Through surface roughness measurement and SEM analysis, it was found that the acid-etched surfaces showed higher roughness values than the sandblasted ones. Scanning electron microscope analysis showed that the cells on the disks treated with acid-etching and acid-etching with vacuum firing spread as well as the sandblasted ones. There were no significant differences in cell proliferation and collagen production on cpTi among the four different surface treatments. Based on the results of this study, it was concluded that etching with concentrated sulfuric acid was a simple and effective way to roughen the surface of titanium without compromising its biocompatibility.

“…The porous and rough surface of dioxide coating can provide a larger contact area at the sample-medium interface when being soaked in the culture medium, which can facilitate the adsorption of proteins in the culture medium and favorable for promoting cell attachment, spreading, proliferation, and differentiation [23,24] . Moreover, the surface chemical species for a biomaterial may be a more dominant factor than its topography in the cell-material interactions [25] .…”

“…Roughness and surface topography are important parameters in biocompatible coatings [16,17]. Roughness measurements of the HVOF coatings were carried out by two different techniques: (i) tactile roughness tester (profilometer Mitutoyo Surftest 301, Mitutoyo, Japan) and (ii) confocal microscopy, which is a noncontact optical imaging profiler (PLu 2300 Optical Profiler, Sensofar-Tech, SL, Barcelona, Spain).…”

Nanostructured titania/hydroxyapatite composite coatings deposited by high velocity oxy-fuel (HVOF) spraying Gaona, M.; Lima, R. S.; Marple, B. R.Contact us / Contactez nous: nparc.cisti@nrc-cnrc.gc.ca. AbstractPure nanostructured titania (TiO 2 ) and blends with 10 and 20 wt% hydroxyapatite (HA) powders were sprayed onto Ti-6Al-4V substrates using a high velocity oxy-fuel (HVOF) system. The feedstock powders employed in this work were engineered to exhibit similar particle size distributions in order to generate similar values of particle temperature and velocity in the spray jet. By achieving these characteristics it was assumed that the differences in coating properties and microstructures produced in this study were mainly related to the nature and composition of the feedstock powders, rather than to the spraying parameters or in-flight particle characteristics. The microstructure, porosity, roughness, Vickers hardness and bond strength (ASTM C633) of these coatings were analyzed and evaluated. X-ray diffraction (XRD) patterns showed that no detectable chemical reaction occurred between the nanostructured TiO 2 and HA phases during the spray process. Due to the poor mechanical performance of HA, its addition decreased the bond strength and hardness values of the coatings, especially when the content of HA was 20 wt%; however, the bond strength values were still much superior to those of HA thermally sprayed coatings. The addition of HA to nanostructured titania for producing HVOF-sprayed coatings could be very interesting for biomedical applications due to the combination of the good mechanical performance and chemical stability of nanostructured titania and a bioactive phase (HA) that can enhance the bio-performance of the coating.
