Abstract: Curable dental compositions, dental articles, and methods of making or using such compositions or articles are described. In one embodiment, the curable dental restoration composition comprises a resin system comprising a free-radically polymerizable semi-crystalline resin having a molecular weight no greater than 3000 g/mole and at least 50 wt-% of nanocluster filler.

Abstract: 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.

Abstract: A dental article includes an external layer formed of a self-supporting hardenable preformed material having a dental article shape defined by an external layer surface. The external layer defines an interior volume. An interior material is disposed within the interior volume. The interior material is different than the external hardenable preformed material and the interior material has a yield stress value of 100 dyn/cm2 or greater.

Abstract: 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.

Abstract: Preformed malleable dental crowns with a side-generic external shape with a plane of symmetry in the facial-lingual direction and/or a plane of symmetry in the mesial-distal direction. The preformed dental crowns also include a hardenable composition that has sufficient malleability such that the side-generic external shape can be formed into, e.g., a left-side specific or right-side specific adjusted external shape. Methods of the invention may include fitting the dental crowns by adjusting or forming them to provide side-specific features, followed by hardening of the hardenable composition.
