A dental restoration device, comprising:
- a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement;
- and
- a crown having an exterior surface and an interior surface that is mated to the exterior surface of the sleeve and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown,
- wherein a thickness of the crown at an occlusal side thereof is greater than a thickness of the sleeve at an occlusal side thereof,
- wherein the sleeve and the crown are each pre-fabricated with respect to a preparation of a tooth upon which the dental restoration device is to be installed and configured to be installed on the prepared tooth,
- wherein the crown is a permanent crown, and
- wherein the dental cement is a light-curing cement and the sleeve is at least partially translucent to light.
