Abstract

A dental article includes a shell defining a volume, the shell including a circumferential base and an incisal/occlusal region distal from the circumferential base. A hardenable dental composition is located within the volume of the shell, and an isolation film is located at the circumferential base of the shell.

First claim

What is claimed is:

1. A sealed package comprising an opening and an interior, and a seal overlying the opening, wherein the interior of the sealed package contains a dental article comprising: a shell in a shape of a crown, a bridge, a veneer, a tooth facsimile, or restoration, or an implant healing cap, the shell defining a volume and comprising a circumferential base and an incisal/occlusal region distal from the circumferential base, wherein the circumferential base of the shell defines an opening adapted to receive a dental structure; a hardenable dental composition located within the volume of the shell, wherein the hardenable dental composition exhibits a yield stress from 50 Pa to 4,000 Pa at 37° C., and wherein the hardenable dental composition comprises a photopolymerizable polymeric resin; and an isolation film, and an inset located within the shell of the dental article, wherein the inset comprises a material chosen from ceramics, glass ceramics, and composites of resins and ceramics.

2. The sealed package of claim 1 , wherein the shell of the dental article comprises a material chosen from acrylics, polyacrylonitriles, polyesters, polyamides, polyureas, polyolefins, polystyrenes, polycarbonates, and polyvinylchloride, and wherein the shell is not substantially distorted by a seating force from 2 N to 20 N.

3. The sealed package of claim 1 , wherein the circumferential base of the dental article includes at least one flange extending in the facial/buccal direction, in the lingual direction, or in both the facial/buccal and lingual directions.

4. The sealed package of claim 1 , wherein the isolation film of the dental article is a single layer or multilayered polymeric film that is radially stretchable by at least 100 percent without causing a perforation in the isolation film.

5. The sealed package of claim 1 , wherein the circumferential base of the dental article comprises a maximum diameter and the isolation film extends beyond the circumferential base by at least 50% of the maximum diameter.

6. The sealed package of claim 1 , wherein the shell of the dental article is continuous.

7. The sealed package of claim 1 , wherein the isolation film of the dental article is unbonded to the circumferential base.

8. The sealed package of claim 1 , wherein the shell of the dental article comprises a vent.

9. The sealed package of claim 1 , wherein the photopolymerizable polymeric resin of the dental article is chosen from epoxy, vinyl ether, and ethylenically unsaturated compounds.

10. The sealed package of claim 9 , wherein the ethylenically unsaturated compounds are chosen from acrylic acid esters, methacrylic acid esters, hydroxy-functional acrylic acid esters, and hydroxy-functional methacrylic acid esters.

11. The sealed package of claim 4 , wherein the polymeric film comprises linear low density polyethylene, ethylene vinyl acetate (EVA) copolymers.

12. A dental restoration system, comprising: (a) a dental article, comprising: (1) a shell in a shape of a crown, a bridge, a veneer, a tooth facsimile, or restoration, or an implant healing cap, the shell defining a volume and comprising a circumferential base and an incisal/occlusal region distal from the circumferential base, wherein the circumferential base of the shell defines an opening adapted to receive a dental structure; and (2) a hardenable dental composition located within the volume of the shell, wherein the hardenable dental composition exhibits a yield stress from 50 Pa to 4,000 Pa at 37° C., and wherein the hardenable dental composition comprises a photopolymerizable polymeric resin; and (b) an isolation film configured for placement between the circumferential base of the dental article and a dental structure during a restoration procedure; wherein the dental restoration system resides within a sealed package, and an inset located within the shell of the dental article, wherein the inset comprises a material chosen from ceramics, class ceramics, and composites of resins and ceramics.

13. The system of claim 12 , wherein the shell of the dental article comprises a material chosen from acrylics, polyacrylonitriles, polyesters, polyamides, polyureas, polyolefins, polystyrenes, polycarbonates, and polyvinylchloride, and wherein the shell is not substantially distorted by a seating force from 2 N to 20 N.

14. The system of claim 12 , wherein the circumferential base of the dental article includes at least one flange extending in the facial/buccal direction, in the lingual direction, or in both the facial/buccal and lingual directions.

15. The system of claim 12 , wherein the isolation film of the dental article is a single layer or multilayered polymeric film that is radially stretchable by at least 100 percent without causing a perforation in the isolation film.

16. The system of claim 12 , wherein the shell of the dental article comprises a vent.

17. The system of claim 12 , wherein the photopolymerizable polymeric resin of the dental article is chosen from epoxy, vinyl ether, and ethylenically unsaturated compounds.

18. The system of claim 15 , wherein the polymeric film comprises linear low density polyethylene, ethylene vinyl acetate (EVA) copolymers.

19. A dental article, comprising: a shell in a shape of a crown, a bridge, a veneer, a tooth facsimile, or restoration, or an implant healing cap, the shell defining a volume and comprising a circumferential base and an incisal/occlusal region distal from the circumferential base, wherein the circumferential base of the shell defines an opening adapted to receive a dental structure; an inset Within the shell, wherein the inset comprises a material chosen from ceramics, glass ceramics, and composites of resins and ceramics; a hardenable dental composition located within the volume of the shell, wherein the hardenable dental composition exhibits a yield stress from 50 Pa to 4,000 Pa at 37° C., and wherein the hardenable dental composition comprises a photopolymerizable polymeric resin; and an isolation film.
