Abstract:
A dental implant is formed of an implant fixture for installation in the jawbone, an abutment secured non-rotationally to the implant fixture by interengaging connector components, and a coping screw removably securing the implant fixture and abutment together. To prevent unintended loosening of the coping screw, the non-circular shank of a locking member is inserted in a correspondingly shaped bore in the coping screw and laterally extending locking keys on the head of the locking member are captured in longitudinal grooves in the abutment, whereby the coping screw is secured positively against loosening.
