Abstract
The osteointegration of osseous fixing implants may be improved through a series of surface treatments. These treatments comprise a cleaning and passivation process, the application of a coating of Ca.sub.U P.sub.V H.sub.X O.sub.Y C.sub.Z to the implant, where subindexes u, v, x, y, and z are natural numbers including zero with variable stoichiometry, and a sterilization process by irradiation. The flexibility of this method provides for the control of physical and chemical properties of the obtained surface in order to match the properties with those of the bone in which the implant will be placed.
