Orthodontic protection device
An easily applied device is described that protects the soft tissues inside of the mouth from abrasion by orthodontic braces. The device consists of a putty-like, moldable material that may be pressed onto and into and molded about the brackets and wires of orthodontic braces, and a plasticized and dehydrated or partially dehydrated hydrogel-forming layer on those surfaces of the device that contact the braces and teeth so as to absorb saliva and dry to some extent the surfaces to which the device is pressed and to offer initial adhesion of the device to the teeth and/or braces.
1. An orthodontic protection device comprising:
a protective layer shaped to fit over a facial surface of at least one tooth and any orthodontic appliances affixed to the facial surface of the of at least one tooth wherein composed substantially of a moldable material; and
an adhesive layer including at least one hygroscopic polymeric material;
wherein the moldable material is a plastically deformable, silicone base material chosen from the group consisting of a polydimethylsiloxane and a vinyl-functionalized polydimethylsiloxane where either or both are compounded (mixed or combined) or in a mixture with either one or both of: a silica or a trimethylated silica.
2. The orthodontic protection device of claim 1 , wherein the device comprises an elongated member with opposing walls defining a longitudinal channel.
3. The orthodontic protection device of claim 2 , wherein the elongated member has a substantially uniform cross-sectional configuration.
4. The method of claim 3 , wherein the adhesive layer further includes a plasticizer.
5. The orthodontic protection device of claim 1 , wherein adhesive layer further includes a hydrophilic plasticizer.
6. The orthodontic protection device of claim 5 , wherein the hydrophilic plasticizer is a polyol or polyol ester.
7. The orthodontic protection device of claim 1 , wherein subsequent to initial application, the moldable material is such that a user can mold the device to the teeth and braces to achieve a tight fit onto the orthodontic appliance by pinching or otherwise exerting finger pressure to the device without the need to apply heat to the moldable material.
8. The orthodontic protection device of claim 1 , wherein the moldable material has a glass transition temperature below about 37° C.
9. The orthodontic protection device of claim 1 , wherein the device comprises a shape having an outer perimeter defined by an outer rim, with a cavity region defined thereby.
10. The orthodontic protection device of claim 1 , wherein
the hygroscopic polymeric material comprises at least one material chosen from the group consisting of a polyvinylpyrrolidone, polyoxazoline, starch, polyacrylic acid, a polyacrylate, a polyvinyl alcohol, a carbomer, a cellulose derivative, a polysaccharide, xanthan, pectin, and guar gum, a natural gum, and copolymers comprising two or more monomer types from the polymers so listed.
11. The orthodontic protection device of claim 1 , wherein the protective layer is shaped to fit over the facial surfaces of a single tooth and any orthodontic appliance or orthodontic appliances affixed to the facial surface of the single tooth.
12. A method of fabricating an orthodontic protection device comprising:
providing a moldable material suitably shaped to temporarily cover an orthodontic implement in a user's mouth, wherein the moldable material is a plastically deformable, silicone base material chosen from the group consisting of a polydimethylsiloxane and a vinyl-functionalized polydimethylsiloxane where either or both are compounded (mixed or combined) or in a mixture with either one or both of: a silica or a trimethylated silica; and
coating a surface of the moldable material with an adhesive layer which includes a hygroscopic polymer.
13. The method of claim 12 further comprising the step of dehydrating the adhesive layer.
14. The method of claim 13 , wherein the step of dehydrating is via application of heat.
15. The method of claim 12 , wherein the moldable material comprises a polymeric material.
16. The method of claim 15 , wherein the adhesive layer further includes a hydrophilic plasticizer and the hydrophilic plasticizer is a polyol, a polyol ester, or a polyol and a polyol ester.
17. The method of claim 12 , wherein the moldable material has a glass transition temperature below about 37° C.
18. The method of claim 12 , wherein the moldable material comprises:
a silicone polymer compounded (mixed, combined) or in a mixture with either one or both of silica or trimethylsilylated silica.
19. The method of claim 12 , wherein the hygroscopic polymer comprises:
at least one material from the group consisting of: a polyvinylpyrrolidone, a polyoxazoline, a starch, a polyacrylic acid, a polyacrylate, a polyvinyl alcohol, a carbomer, a cellulose derivative, xanthan, pectin, guar gum, a natural gum, and copolymers comprising two or more monomer types from any of above.
20. An orthodontic protection device comprising:
a protective layer shaped to fit over a facial surface of at least one tooth and any orthodontic appliances affixed to the facial surface of the of at least one tooth wherein composed substantially of a moldable material; and
an adhesive layer including at least one hygroscopic polymeric material applied to the protective layer on a surface opposite the facial surface;
wherein the moldable material is a plastically deformable, silicone base material chosen from the group consisting of a polydimethylsiloxane and a vinyl-functionalized polydimethylsiloxane where either or both are compounded (mixed or combined) or in a mixture with either one or both of: a silica or a trimethylated silica.
21. The orthodontic protection device of claim 20 , wherein the adhesive layer further comprises a hydrophilic plasticizer.
