Abstract
A metal grid is embedded in the contact surface of a plastic implant in order to increase the wear resistance of the plastic implant. The ridge dimensions of the metal grid are chosen so that the elasticity of the plastic implant is not unduly reduced. An additional anchoring surface formed of layers of porous metal may be secured to the embedded grid to provide a surface into which bone tissue may grow in a cementless anchorage.
