Abstract

A fabric ribbon for use in dental applications. The fabric ribbon includes a transverse set of fibers aligned generally transverse to a length of the ribbon; and a axial set of fibers, intertwined around the transverse set of fibers and aligned generally axially along the length of the ribbon, each of the axial set of fibers having a thickness greater than a thickness of each of the transverse set of fibers. The fabric ribbon may be used for a dental appliance, for example in a periodontal splint, a pontic beam, a composite restoration, or to bridge a crack in teeth.

Claims

1. A fabric ribbon for use in a reinforced plastic composite, comprising:

a transverse set of fibers aligned generally transverse to a length of the ribbon; and

an axial set of fibers, intertwined around the transverse set of fibers and aligned generally axially along the length of the ribbon, each of the fibers in the axial set of fibers having a thickness greater than a thickness of each of fibers in the transverse set of fibers.

2. The composite of claim 1, wherein the ribbon is a leno weave fabric.

3. The composite of claim 2, wherein the transverse set of fibers comprises filler or weft fibers for the leno weave fabric and the axial set of fibers comprises warp fibers for the leno weave fabric.

4. The composite of claim 3, wherein a ratio of the diameter of the fibers in the axial set of fibers to the diameter of the fibers in the transverse set of fibers is at least 1.1 to 1.

5. The composite of claim 4, wherein a ratio of the diameter of the fibers in the axial set of fibers to the diameter of the fibers in the transverse set of fibers is at least greater than or equal to 2 to 1.

6. The composite of claim 5, wherein a ratio of the diameter of the fibers in the axial set of fibers to the diameter of the fibers in the transverse set of fibers is at least greater than or equal to 6 to 1.

7. A dental appliance, comprising:

a fabric ribbon for use in a reinforced plastic composite, comprising;

a transverse set of fibers aligned generally transverse to a length of the ribbon; and

an axial set of fibers, intertwined around the transverse set of fibers and aligned generally axially along the length of the ribbon, each of the fibers in the axial set of fibers having a thickness greater than a thickness of each of the fibers in the transverse set of fibers.

8. The dental appliance of claim 7, further comprising a resin matrix applied to the fabric ribbon.

9. The dental appliance of claim 7, wherein the ribbon is a leno weave fabric.

10. The dental appliance of claim 9, wherein the transverse set of fibers comprises filler or weft fibers for the leno weave fabric and the axial set of fibers comprises warp fibers for the leno weave fabric.

11. The dental appliance of claim 9, wherein a ratio of the diameter of the fibers in the axial set of fibers to the diameter of the fibers in the transverse set of fibers is at least 1.1 to 1.

12. The dental appliance of claim 9, wherein a ratio of the diameter of the fibers in the axial set of fibers to the diameter of the fibers in the transverse set of fibers is at least greater than or equal to 2 to 1.

13. The dental appliance of claim 9, wherein a ratio of the diameter of the fibers in the axial set of fibers to the diameter of the fibers in the transverse set of fibers is at least greater than or equal to 6 to 1.

14. A method of reinforcing a tooth or teeth of a patient, comprising:

applying a fabric ribbon to a patient'"'"'s tooth or teeth, the fabric ribbon comprising;

a transverse set of fibers aligned generally transverse to a length of the ribbon; and

an axial set of fibers, intertwined around the transverse set of fibers and aligned generally axially along the length of the ribbon, each of the fibers in the axial set of fibers having a thickness greater than a thickness of each of fibers in the transverse set of fibers; and

bonding the fabric ribbon to the patient'"'"'s tooth or teeth using a resin.

15. The method of claim 14, wherein applying the fabric ribbon comprises applying the fabric ribbon over multiple teeth so as to form a periodontal splint.

16. The method of claim 14, wherein applying the fabric ribbon comprises applying the fabric ribbon over multiple teeth so as to form a pontic beam.

17. The method of claim 14, wherein applying the fabric ribbon comprises applying the fabric ribbon on a single tooth so as to form a composite restoration.

18. The method of claim 14, wherein applying the fabric ribbon comprises applying the fabric ribbon across a crack in a single tooth to bridge the crack.
