Pearlescent white aligners

1. An orthodontic remodeling device, comprising:

a) an aligner made of a polyurethane resin and having lingual, occlusal and facial surfaces,

b) said aligner being shaped to intimately contact a plurality of teeth in an arch and apply sufficient pressure to at least one tooth in said arch to move said at least one tooth,

c) wherein at least the facial surfaces of said aligner are a pearlescent white having a refractive index of 1.5-1.63 under visible light and wet conditions.

2. The orthodontic remodeling device of claim 1 , wherein said lingual, occlusal and facial surfaces are each pearlescent white.

3. The orthodontic remodeling device of claim 1 , said aligner made with a transparent resin containing ceramic or porcelain or glass reflective particles.

4. The orthodontic remodeling device of claim 1 , said aligner made with a transparent resin containing glass microspheres.

5. The orthodontic remodeling device of claim 1 , said aligner comprising a resin and a pearlescent white coating or a transparent resin containing a pearlescent white pigment filler.

6. The orthodontic remodeling device of claim 1 , said aligner comprises a transparent resin and a pearlescent white pigment applied as a coating or a filler.

7. The orthodontic remodeling device of claim 1 , said aligner comprises a transparent resin and a pearlescent white pigment coating or filler, said pearlescent white pigment having refractive index at least 0.03 greater than a refractive index of said transparent resin.

8. The orthodontic remodeling device of claim 1 , said aligner comprises a transparent resin and a pearlescent white pigment comprising a mica powder coated with titanium dioxide or iron oxide.

9. The orthodontic remodeling device of claim 5 , further comprising a clear coating over an outermost layer of said aligner.

10. The orthodontic remodeling device of claim 1 , said aligner made of a polyurethane resin with a pearlescent white pigment selected from the group consisting of amorphous ceramic particles, glass particles, 10-40 μm mica powder with TiO 2 and/or FeO coating, barium silicate particles, barium aluminosilicate particles, barium borosilicate particles, and strontium borosilicate particles.

11. An improved orthodontic aligner, the orthodontic aligner shaped to intimately contact a plurality of teeth or all teeth in an arch and apply sufficient pressure to at least one tooth in said arch to move said tooth, the improvement comprising a pearlescent white pigment that is i) intimately admixed with a polyurethane resin of said aligner or ii) in a coating on a polyurethane resin of said aligner, such that said aligner has a pearlescent white coloration and an index of refraction of visible light of 1.5-1.63 when wet.

12. The improved orthodontic aligner of claim 11 , said pearlescent pigment being a mica powder coated with titanium dioxide or iron oxide or both.

13. The improved orthodontic aligner of claim 11 , wherein the aligner is capable of being used together with force attachments that are adapted to attach to a tooth and provide a surface that said aligner can apply force to.

14. The improved orthodontic aligner of claim 11 , said aligner made of a polyurethane resin blended with a pearlescent white pigment selected from the group consisting of reflective particles of 10-40 μm, said particles selected from the group consisting of amorphous ceramic particles, glass particles, mica powder with TiO 2 and/or FeO coating, barium silicate particles, barium aluminosilicate particles, barium borosilicate particles, and strontium borosilicate particles.

15. A method of orthodontic remodeling comprising wearing the aligner of claim 1 for a period of time sufficient to affect orthodontic remodeling.

16. A method of orthodontic remodeling comprising wearing the aligner of claim 11 for a period of time sufficient to affect orthodontic remodeling.
