Method and apparatus for dental crown restorations using prefabricated sleeve-crown pairs
A dental restoration device includes 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 crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

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 gingival end of the crown is substantially co-planar with a gingival end of the sleeve,
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.
9. The dental restoration device of claim 8 , wherein the exterior surface of the crown has a shape including at least one cusp and the interior surface of the crown has a shape that is inverted with respect to the shape of the exterior surface of the crown.
10. The dental restoration device of claim 8 , wherein the crown includes a polymer with ceramic and/or glass particles suspended therein.
11. The dental restoration device of claim 8 , wherein the sleeve includes a polymer.
12. The dental restoration device of claim 8 , wherein the dental cement has a high Young's modulus within a range of 2 and 60 GPa in a cured state.
13. The dental restoration device of claim 8 , wherein the sleeve has a high Young's modulus within a range of 2 and 60 GPa.
14. The dental restoration device of claim 8 , wherein both the sleeve and the crown are non-porous.
15. 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 sleeve is pre-fabricated as rigid and having a fixed shape, and
wherein the dental cement is a light-curing cement and the sleeve is at least partially translucent to light.
16. The dental restoration device of claim 15 , wherein the exterior surface of the crown has a shape including at least one cusp and the interior surface of the crown has a shape that is inverted with respect to the shape of the exterior surface of the crown.
17. The dental restoration device of claim 15 , wherein the crown includes a polymer with ceramic and/or glass particles suspended therein.
18. The dental restoration device of claim 15 , wherein the sleeve includes a polymer.
19. The dental restoration device of claim 15 , wherein the dental cement has a high Young's modulus within a range of 2 and 60 GPa in a cured state.
20. The dental restoration device of claim 15 , wherein the sleeve has a high Young's modulus within a range of 2 and 60 GPa.
21. 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 gingival end of the crown is substantially co-planar with a gingival end of the sleeve,
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 sleeve is pre-fabricated as rigid and having a fixed shape, and
wherein the dental cement is a light-curing cement and the sleeve is at least partially translucent to light.
