Abstract
An abutment lock utilized with an implant anchor which has a substantially smooth axial bore which may have longitudinal guide grooves formed therein. The abutment element has an insertion end which is also substantially smooth and which terminates in an oblique lower surface. A bore through the abutment allows a threaded bolt to engage a wedge nut having a cooperatively formed oblique surface and a plurality of guide protrusions such that rotation of the bolt urges the nut against the abutment oblique surfaces thereby urging the smooth surfaces of the nut and abutment into intimate surface to surface contact with the cylindrical wall of the anchor. The relatively large surface area in compressive contact between the abutment and the anchor resists movement between the components.
