Abstract

A dental prosthetic assembly includes a semi-flexible reinforcement bar and a polymer and glass outer layer chemically luted to the semi-reinforcement bar outside of the reinforcement bar. The semi-flexible reinforcement bar forms an interior of the dental prosthetic assembly and at least a portion of the polymer and glass outer layer forms teeth of the dental prosthetic assembly. A coupling system of a dental prosthetic assembly includes pins disposed in openings extending into the dental prosthetic assembly and implant abutments configured to be coupled with a mouth of a patient. The implant anchors have horizontal holes configured to receive the pins. The pins secure the dental prosthetic assembly to the implant abutments by moving into the dental prosthetic assembly through the openings and into the holes of the implant abutments.

Claims

1. A dental prosthetic assembly comprising:

a semi-flexible reinforcement bar; and

a polymer and glass outer layer chemically luted to the semi-flexible reinforcement bar outside of the reinforcement bar using a dual cure bonding system, wherein the reinforcement bar forms an interior of the dental prosthetic assembly and at least a portion of the polymer and glass outer layer forms teeth of the dental prosthetic assembly.

2. The dental prosthetic assembly of claim 1, wherein the semi-flexible reinforcement bar has a density that is less than density of titanium or density of zirconia.

3. The dental prosthetic assembly of claim 1, wherein the semi-flexible reinforcement bar is more flexible than titanium when subjected to a common amount of force.

4. The dental prosthetic assembly of claim 1, wherein the semi-flexible reinforcement bar is formed from a copolyester resin having nanoceramic particles in the resin.

5. The dental prosthetic assembly of claim 1, wherein the semi-flexible reinforcement bar is more flexible than the polymer and glass outer layer when subjected to a common amount of force.

6. The dental prosthetic assembly of claim 1, wherein the polymer and glass outer layer is formed from a glass filled resin.

7. The dental prosthetic assembly of claim 1, wherein the polymer and glass outer layer is formed from a resin having silanted glass in the resin.

8. The dental prosthetic assembly of claim 1, wherein the polymer and glass outer layer is less porous than acrylic.

9. The dental prosthetic assembly of claim 1, further comprising a dual cure resin chemically bonding the reinforcement bar to the polymer and glass outer layer.

10. The dental prosthetic assembly of claim 1, further comprising a tissue-colored exterior coating on less than an entirety of an exterior surface of the polymer and glass outer layer.

11. A coupling system of a dental prosthetic assembly, the coupling system including:

pins configured to move in and out of openings extending into the dental prosthetic assembly; and

implant abutments configured to be coupled with a mouth of a patient, the implant abutments having horizontal holes configured to receive the pins, wherein the pins secure the dental prosthetic assembly to the implant anchors by moving into the dental prosthetic assembly through the openings and into the holes of the implant abutments.

12. The coupling system of claim 11, wherein the openings in the dental prosthetic assembly are laterally oriented with respect to teeth of the dental prosthetic assembly, and the pins are actuated in first lateral directions in the openings to secure the dental prosthetic assembly to the implant abutments.

13. The coupling system of claim 11, wherein the pins are actuated in opposite second lateral directions in the openings to detach the dental prosthetic assembly from the implant abutments.

14. The coupling system of claim 11, wherein the implant abutments are sized to fit into recesses in the dental prosthetic assembly.

15. The coupling system of claim 11, wherein the openings in the dental prosthetic assembly laterally extend from outside of the dental prosthetic assembly into the recesses in the dental prosthetic assembly.

16. A method comprising:

obtaining a semi-flexible reinforcement bar;

obtaining a polymer and glass outer layer;

chemically bonding the semi-flexible reinforcement bar with the polymer and glass outer layer; and

milling artificial teeth into the polymer-based outer layer to form a dental prosthetic assembly, wherein the reinforcement bar forms an interior of the dental prosthetic assembly.

17. The method of claim 16, wherein the semi-flexible reinforcement bar has a density that is less than density of titanium or density of zirconia.

18. The method of claim 16, wherein the semi-flexible reinforcement bar is more flexible than titanium when subjected to a common amount of force.

19. The method of claim 16, wherein the semi-flexible reinforcement bar is formed from a copolyester resin having nanoceramic particles in the resin.

20. The method of claim 16, wherein the semi-flexible reinforcement bar is more flexible than the polymer and glass outer layer when subjected to a common amount of force.
