A method of processing a surface of a metallic implant, such as a dental implant, to provide a desirable surface roughness, comprising subjecting the metallic implant to blasting with particles of one or more titanium oxides, including at least one non-stoichiometric titanium oxide, the particles having a compact morphology and a particle size in the range of from 1 to 300 μm. The resulting implant surface showed unexpectedly high retention strength after implantation in bone.
