    摘要： Provided are abrasive assemblies and related methods that combine a head portion including an integral abrasive member and a drive portion including a resilient cylindrical mandrel. The abrasive member has a receptacle that is complemental to a working end of the mandrel when both members are relaxed. As the abrasive member engages to, or disengages from, the mandrel, the receptacle resiliently expands and the working end of the mandrel resiliently compresses, each in cooperation with the other. Optionally, the abrasive member is maintained in compression in both directions parallel and perpendicular to the longitudinal axis of the mandrel. Advantageously, these assemblies provide for superior retention and slip resistance, ease-of-use, and high manufacturing tolerances.

    摘要： A solid dental crown and methods of using the solid dental crown are disclosed. The solid dental crown includes, a self-supporting solid hardenable preformed dental crown having an external crown shape defined by an external crown surface. The external crown surface defines a crown volume that is substantially filled with a hardenable composition. The hardenable composition has sufficient malleability so that the solid preformed dental crown can be pressed onto a prepared tooth surface to form a recess in the solid preformed dental crown defined by a recess surface that is complimentary to the prepared tooth surface.
