The metallic substrate provides structural strength and the enamel provides chemical stability, resistance to wear, tissue compatibility, progressive ingrowth and electrical insulating properties. The implant may be produced by coating a portion of the metallic substrate with a partially crystallized enamel, and then positioning the implant on a firing support with the partially crystallized enamel in contact with the support and coating the remaining non-enamelled surface.
