ABSTRACT:
A system for driving and tightening components in a dental prosthodontic restoration. The system comprises at least a first driver having a body portion and a shank portion depending from the body portion, the body portion including a socket and a bore axially disposed through the body portion and opening through to the socket, the shank portion having a predetermined driver structure at one end. The system includes at least a first torque element comprising an outer member and an inner member, the inner member aligned with respect to the outer member and attached thereto by one or more spokes, the outer member having a predetermined geometry to enable the outer member to be received in the socket of the driver. A mandrel is also provided and includes a first portion received in the inner member of the torque element and a second portion received in the bore when the mandrel, the torque element and the driver are assembled together. Upon rotation of the mandrel, the inner member of the torque element rotates with respect to the outer member of the torque element only while the spokes are intact. The number of spokes and the placement of the spokes relative to the inner and outer members of the torque element are predetermined such that upon rotation of the mandrel the spokes remain intact provided the torque applied to the mandrel is below a predetermined level.
