Abstract
A method for texturing of selected surfaces on a spinal implant. The implant is pretreated with an EDM process by passing the implant by an electrode along an axis, at a predetermined speed, voltage and current. The implant is further conditioned by Al2O3 grit blasting followed by an acidic solution bath and process water rinse, which yields a surface porosity and topography conducive to osseointegration on the surface of the spinal implant.
Claims8
A method of treating surfaces on medical implants for osseointegration comprising the steps of:
- placing an implant in a body of dielectric water;
- juxtapositioning an electrode to the implant;
- exposing the implant surface to said electrode through an EDM process with a voltage for a period of time to obtain a porosity on the surface of the implant;
- grit blasting a surface of the implant to obtain an average surface roughness Ra value of 5 microns;
- bathing the implant with an acidic solution;
- rinsing the implant with process water to yield a surface porosity and topography conducive to osseointegration on the surface of the spinal implant.
