Hydroxyapatite (HA) and other forms of bioceramics coatings had been reported to stimulate bone healing, which helps in initial implant integration. This study was to evaluate the effectiveness of air blasting with two combinations of bioceramic powders (hydroxyapatite and calcium oxide) on the selected implant surfaces for surface deposition. Five different types of implant disks were tested, namely Commercially pure (Cp), Sandblasted (SB), Sandblasted and etched(SBE), SLActive®, Roxolid®. The studied samples were blasted with apatite abrasive bioceramic powders, 95% Hydroxyapatite (HA)/5% Calcium Oxide (CaO) and 90% Hydroxyapatite (HA)/10% Calcium Oxide (CaO). The surface and elemental differences between the blasted samples were compared using a Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS). Results after surface treatment had demonstrated changes in surface morphologies; most evidently on the Cp implant discs. All treated surfaces revealed a non-uniform distribution of the treatment on the surface layer, with dispersed patches of bioceramic powders over the surfaces. The experimental blasting method used in this study has demonstrated the ability to deposit bioceramic materials on different implant surfaces.
