Abstract

A mouthguard according to an embodiment of the present disclosure includes an occlusion portion that is configured to be disposed between and engaged by at least some of the upper teeth and at least some of the lower teeth of a wearer. The mouthguard further includes a protection portion coupled to the occlusion portion. The protection portion is configured to be disposed laterally and anteriorly relative to the upper teeth of the wearer. The protection portion includes an interior surface that is configured to face toward the teeth of the wearer. The protection portion further includes an exterior surface opposite the interior surface and configured to face away from the teeth of the wearer. At least a portion of the exterior surface is a textured surface.

First claim

What is claimed:

1. A mouthguard comprising:
an occlusion portion configured to be disposed between and engaged between at least some of the teeth of a wearer, the occlusion portion comprising:
a base comprising a first material having a first hardness;
an inferior bite layer coupled to the base by extending into one or more through holes formed in the base and configured to be engaged by at least some of the lower teeth of the wearer, the inferior bite layer comprising a second material having a second hardness, the second hardness being greater than the first hardness;

a protection portion coupled to the occlusion portion, the protection portion configured to be disposed laterally and anteriorly relative to the teeth of the wearer, the protection portion comprising:
an interior surface configured to face toward the teeth of the wearer; and
an exterior surface opposite the interior surface and configured to face away from the teeth of the wearer.

2. The mouthguard of claim 1 , wherein the inferior bite layer is a right inferior bite layer configured to be engaged by the right lower molars of the wearer, and further comprising a left inferior bite layer configured to be engaged by the left lower molars of the wearer.

3. The mouthguard of claim 2 , wherein the base comprises a lower surface disposed between the right inferior bite layer and the left inferior bite layer, the lower surface configured to be engaged by the lower teeth of the wearer.

4. The mouthguard of claim 1 , wherein the protection portion has a first thickness between the interior surface and the exterior surface, the inferior bite layer has a second thickness extending in a superior-inferior direction, and the first thickness is greater than the second thickness.

5. The mouthguard of claim 4 , wherein the first thickness is in a range from 150 percent to 50 percent greater than the second thickness.

6. The mouthguard of claim 1 , wherein the protection portion comprises the first material.

7. The mouthguard of claim 1 , wherein the second material comprises a copolymer of ethylene and vinyl acetate (EVA).

8. The mouthguard of claim 1 , wherein the second material comprises a thermoplastic rubber.

9. The mouthguard of claim 1 , wherein the second material comprises polypropylene.

10. The mouthguard of claim 1 , wherein the second material comprises a high molecular weight linear polyester derived from caprolactone monomer.

11. The mouthguard of claim 1 , wherein the second material comprises polypropylene.

12. The mouthguard of claim 1 , wherein the protection portion further comprises a plurality of through holes extending from the interior surface to the exterior surface.

13. The mouthguard of claim 1 , wherein the first material comprises polycaprolactone.

14. The mouthguard of claim 1 , wherein at least a portion of the exterior surface is a textured surface.

15. A mouthguard comprising:
an occlusion portion configured to be disposed between and engaged between at least some of the teeth of a wearer, the occlusion portion comprising:
a base comprising a first material having a first hardness;
an inferior bite layer coupled to the base and configured to be engaged by at least some of the lower teeth of the wearer, the inferior bite layer comprising a second material having a second hardness, the second hardness being greater than the first hardness;
a superior bite layer coupled to the base and configured to be engaged by at least some of the upper teeth of the wearer;

a protection portion coupled to the occlusion portion, the protection portion configured to be disposed laterally and anteriorly relative to the teeth of the wearer, the protection portion comprising:
an interior surface configured to face toward the teeth of the wearer; and
an exterior surface opposite the interior surface and configured to face away from the teeth of the wearer.

16. The mouthguard of claim 15 , wherein the superior bite layer comprises a third material having a third hardness, the third hardness being different than the first hardness.

17. The mouthguard of claim 16 , wherein the third hardness is greater than the first hardness.

18. The mouthguard of claim 16 , wherein the third material comprises a copolymer of ethylene and vinyl acetate (EVA).

19. The mouthguard of claim 15 , wherein the protection portion has a first thickness between the interior surface and the exterior surface, the superior bite layer has a second thickness extending in a superior-inferior direction, and the first thickness is greater than the second thickness.

20. The mouthguard of claim 19 , wherein the first thickness is in a range from 150 percent to 50 percent greater than the second thickness.
