Abstract
The invention defines a surface of a titanium-based metal implant to be inserted into bone tissue, characterised in that it comprises substantially pure titanium oxide and has a thickness of 8-50 nm. Also, the invention defines a procedure for obtaining the surface, as well as the metal implant that exhibits it. This surface exhibits good micrometric roughness and a composition that is practically free from impurities and a thickness that is approximately three times the thickness of conventional surfaces; these characteristics provide it with very good osseointegration properties.

Surface of a titanium-based metal implant to be inserted into bone tissue, characterised in that it comprises substantially pure titanium oxide and has a thickness of 8-50 nm.
Procedure for obtaining a surface of a titanium-based metal implant to be inserted into bone tissue characterised in that it comprises the stages of:
- (a) blasting particles of zirconium oxide under pressure onto the external area of the implant;
- (b) chemically treating the blasted external area of the implant with an acid composition comprising sulfuric and hydrofluoric acids;
- and
- (c) thermally treating the blasted and chemically treated external area of the implant by heating at a temperature of 200-450° C. for 15-120 min.
