Abstract

The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a removable dental appliance includes a shell having a number of tooth apertures configured to receive and reposition a number of teeth of a patient along one jaw of a patient, a repositioning jaw element that extends from a buccal or lingual surface of the shell, the element having a first outer surface oriented to face the tongue of the patient surface and a second outer surface oriented to face the cheek of the patient, and a reinforcement member formed along at least one of the first and second outer surfaces to provide reinforcement of the repositioning jaw element.

First claim

What is claimed is:

1. A removable dental appliance formation system, comprising:
a non-transitory computing device readable medium storing instructions executable by a processor to cause a computing device to perform a method, the method including:
identifying a misaligned jaw of a patient from a virtual image of the patient's jaw; and
providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient, the virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient and wherein the at least one of the first and second repositioning jaw elements has a first outer surface oriented to face the tongue of the patient and a second outer surface oriented to face the cheek of the patient and includes a reinforcement member formed along at least one of the first and second outer surfaces to provide reinforcement of the element.

2. The removable dental appliance formation system of claim 1 , wherein the non-transitory computing device readable medium storing instructions include instructions for fabricating a physical model for forming at least the first shell.

3. The removable dental appliance formation system of claim 2 , wherein the system includes a dental mold formation apparatus for receiving the instructions for fabricating the physical model.

4. The removable dental appliance formation system of claim 3 , wherein the method further includes applying one or more materials to fabricate the physical model.

5. The removable dental appliance formation system of claim 3 , wherein the dental mold formation apparatus comprises a thermo-forming device or a three dimensional printing device.

6. The removable dental appliance formation system of claim 5 , wherein the physical model includes a solid shape onto which a material is thermoformed over to create the first shell of the appliance.

7. The removable dental appliance formation system of claim 6 , wherein the solid form includes a solid shape over which the first repositioning jaw element is formed.

8. The removable dental appliance formation system of claim 7 , wherein the solid form includes a solid shape over which the at least one reinforcement member is formed.

9. The removable dental appliance formation system of claim 6 , wherein the solid form includes the solid shape over which the first repositioning jaw element is formed, wherein the solid shape of the first repositioning jaw element has a first outer surface and a second outer surface and wherein the solid form includes a solid shape over which at least one reinforcement member is formed on each of the first and second surfaces.

10. The removable dental appliance formation system of claim 1 , wherein the non-transitory computing device readable medium storing instructions include instructions for directly fabricating at least the first shell.

11. The removable dental appliance formation system of claim 10 , wherein
directly fabricating comprises three dimensional printing.

12. A removable dental appliance formation system, comprising:
a non-transitory computing device readable medium storing instructions executable by a processor to cause a computing device to perform a method, the method including:
identifying a misaligned jaw of a patient from a virtual image of the patient's jaw; and
providing a treatment plan for the patient including a virtual model of a dental appliance having a shell having a plurality of tooth apertures configured to receive and reposition a plurality of teeth of the patient along a first jaw of the patient, the virtual model of the dental appliance including:

a repositioning jaw element that extends from a buccal or lingual surface of the shell, the element having a first outer surface oriented to face the tongue of the patient and a second outer surface oriented to face the cheek of the patient; and
a reinforcement member formed along at least one of the first and second outer surfaces to provide reinforcement of the repositioning jaw element, the reinforcement member comprising a channel extending from a gingival line of the shell at the repositioning jaw element towards a top of the repositioning jaw element and past an occlusal surface of the tooth apertures of the shell, the channel being open to an interior cavity of the repositioning jaw element.

13. The removable dental appliance formation system of claim 12 , wherein the non-transitory computing device readable medium storing instructions include instructions for fabricating a physical model for forming the shell.

14. The removable dental appliance formation system of claim 13 , wherein the system includes a dental mold formation apparatus for receiving the instructions for fabricating the physical model.

15. The removable dental appliance formation system of claim 14 , wherein the method further includes applying one or more materials to fabricate the physical model.

16. The removable dental appliance formation system of claim 14 , wherein the dental mold formation apparatus comprises a thermo-forming device or a three dimensional printing device.

17. The removable dental appliance formation system of claim 16 , wherein the physical model includes a solid shape onto which a material is thermoformed over to create the first shell of the appliance.

18. The removable dental appliance formation system of claim 17 , wherein the solid form includes a solid shape over which the repositioning jaw element is formed.

19. The removable dental appliance formation system of claim 18 , wherein the solid form includes a solid shape over which the reinforcement member is formed.

20. The removable dental appliance formation system of claim 17 , wherein the solid form includes the solid shape over which the repositioning jaw element is formed, wherein the solid form includes a solid shape over which at least one reinforcement member is formed on each of the first and second surfaces.
