ABSTRACT:
A primary implant member anchored in the jaw receives a secondary member which is held in the primary member by direct engagement by the head of a screw which bottoms in the primary member and O-ring bridges the radial play between these members in a dental implant. As a result, the retention of the secondary member does not depend on the state of the O-ring and the force with which the O-ring is held. Axial mobility and inclination of the secondary member is also permitted by the O-ring bridge.
