Abstract

An orthodontic adhesive includes components capable of allowing easy debonding of an orthodontic device from a patient's tooth. The adhesive includes an engineered marine mussel protein. The adhesive may include at least one photocleavable moiety. The adhesive is applied in one or more individual layers. One of the components of the adhesive is capable of binding to a tooth and the other component may be capable of binding to an orthodontic device. A method of adhering an orthodontic device to a tooth includes applying a layer of an orthodontic adhesive to either the tooth or the orthodontic device or the tooth and the orthodontic device and affixing the orthodontic device to the tooth with the orthodontic adhesive situated between the tooth and the orthodontic device. The engineered marine mussel protein includes one or more catechol moieties or one or more derivatives of a catechol moiety.

Claims (28)

1. A method of adhering an orthodontic device to a tooth comprising:

applying a layer of an orthodontic adhesive system to a tooth surface and/or the orthodontic device, the orthodontic adhesive system comprising:

an engineered marine mussel protein including at least one catechol moiety or catechol derivative moiety, and

a nitrocatechol derivative selected from the group consisting of nitrodopamine, nitronorepinephrine, and nitroepinephrine; and

affixing the orthodontic device to the tooth surface with the orthodontic adhesive system situated between the tooth and the orthodontic device,

wherein the tooth surface is wet.

2. The method of claim 1 , wherein the catechol moiety includes catechol-methacrylate.

3. The method of claim 1 , further comprising:

applying an acrylate moiety and/or a methacrylate moiety onto the layer.

4. The method of claim 3 , wherein the moiety is bis-methacrylate.

5. The method of claim 1 , wherein the orthodontic adhesive system further comprises a sealant.

6. The method of claim 1 , wherein affixing the orthodontic device to the tooth surface comprises curing the orthodontic adhesive system with light.

7. The method of claim 1 , wherein the orthodontic adhesive system exhibits a shear bond strength from 10 MPa to 20 MPa after the orthodontic adhesive system is affixed to the tooth surface.

8. The method of claim 1 , wherein in the applying the orthodontic adhesive system to the tooth surface, the tooth surface is not treated with any compositions before the applying the orthodontic adhesive system to the tooth surface.

9. A method of adhering an orthodontic device to a tooth comprising:

applying a layer of an orthodontic adhesive system to a tooth surface and/or the orthodontic device, the orthodontic adhesive system comprising:

an engineered marine mussel protein including at least one catechol moiety or catechol derivative moiety, and

a nitrocatechol derivative selected from the group consisting of nitrodopamine, nitronorepinephrine, and nitroepinephrine; and

affixing the orthodontic device to the tooth surface with the orthodontic adhesive system situated between the tooth and the orthodontic device,

wherein applying the layer of the orthodontic adhesive system to the tooth surface and/or the orthodontic device is performed without having applied an acid etchant solution to the tooth surface prior to applying the layer of the orthodontic adhesive system to the tooth surface and/or the orthodontic device.

10. The method of claim 9 , wherein the catechol moiety includes catechol-methacrylate.

11. The method of claim 9 , further comprising:

applying an acrylate moiety and/or a methacrylate moiety onto the layer.

12. The method of claim 11 , wherein the moiety is bis-methacrylate.

13. The method of claim 9 , wherein the orthodontic adhesive system further comprises a sealant.

14. The method of claim 9 , wherein affixing the orthodontic device to the tooth surface comprises curing the orthodontic adhesive system with light.

15. The method of claim 9 , wherein the orthodontic adhesive system exhibits a shear bond strength from 10 MPa to 20 MPa after the orthodontic adhesive system is affixed to the tooth surface.

16. The method of claim 9 , wherein in the applying the orthodontic adhesive system to the tooth surface, the tooth surface is not treated with any compositions before the applying the orthodontic adhesive system to the tooth surface.
