Figure 1From: An in vivo evaluation of bone response to three implant surfaces using a rabbit intramedullary rod modelPhotographs of implant surfaces. P = plasma-sprayed titanium (mean Ra = 27 microns); PHA = plasma-sprayed titanium with plasma-sprayed hydroxyapatite coating (mean Ra = 17 microns); CHA = chemical-textured titanium surface (by acid etching) with hydroxyapatite coating (mean Ra = 26 microns). On visual inspection the surface texture of the P surface appear qualitatively more similar to the PHA surface when compared to the CHA surface.Back to article page
