Abstract

The present disclosure provides methods, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include moving at least one tooth with a dental appliance having a first shell configured to receive a plurality of teeth of a patient's upper dentition and separating an upper dentition of a patient from a lower dentition of the patient utilizing the dental appliance. The dental appliance may interface a first surface of a first repositioning jaw element of the first shell with a second surface of a second repositioning jaw element of a second shell of the dental appliance. The dental appliance separates occlusal surfaces of the plurality of teeth of the patient's upper dentition from occlusal surfaces of the plurality of teeth of the patient's lower dentition as the patient moves to a fully engaged sagittal jaw position.

First claim

What is claimed is:

1 . A method of separating occlusal surfaces, comprising:
moving at least one tooth with plurality of sets of dental appliances, each set having a first shell configured to receive a plurality of teeth of a patient's upper dentition, the plurality of teeth comprising the at least one tooth; separating an upper dentition of a patient from a lower dentition of the patient utilizing each of the plurality of sets of dental appliances; and wherein each of the plurality of dental appliances includes interfaces a first surface of a first repositioning jaw element of the first shell with a second surface of a second repositioning jaw element of a second shell, the second shell configured to receive a plurality of teeth of the patient's lower dentition, and wherein the dental appliance separates occlusal surfaces of the plurality of teeth of the patient's upper dentition from occlusal surfaces of the plurality of teeth of the patient's lower dentition as the patient moves to a fully engaged sagittal jaw position wherein each of the plurality of sets of dental appliances is configured to reposition the at least one tooth concurrently with the repositioning of the patient's jaw, and wherein a position of the first repositioning jaw element of each of plurality of sets of removeable dental appliances changes with a change in a midline position of at the least one tooth in a previous stage of the treatment plan.

2 . The method of claim 1 , wherein separating the patient's upper dentition from the patient's lower dentition utilizing the dental appliance includes the dental appliance interfacing a third surface of a third repositioning jaw element of the first shell with a fourth surface of a fourth repositioning jaw element of the second shell.

3 . The method of claim 2 , wherein the dental appliance interfacing the first surface and second surface and interfacing the third surface and the fourth surface includes:
interfacing the first surface and the second surface at a first slant; and interfacing the third surface and the fourth surface at a second slant, wherein the first slant and the second slant include opposing angles.

4 . The method of claim 1 , wherein separating occlusal surfaces includes moving a lower jaw of the patient from an articulation path of opening to a desired range of jaw opening extending from a current occluding position.

5 . The method of claim 1 , wherein separating occlusal surfaces includes separating occlusal surfaces to a threshold distance to prevent an occlusal surface of the first shell from contacting an occlusal surface of the second shell.

6 . The method of claim 1 , including:
separating the occlusal surfaces of the plurality of teeth of the patient's upper dentition from the occlusal surfaces of the plurality of teeth of the patient's lower dentition as the patient moves to the fully engaged sagittal jaw position in a plurality of incremental distances utilizing a plurality of dental appliances; and wherein the plurality of dental appliances include the dental appliance.

7 . The method of claim 1 , wherein:
the first shell having first attachment areas to receive and engage with first attachment elements to retain the first shell on the patient's upper dentition; the second shell having second attachment areas to receive and engage with second attachment elements to retain the second shell on the patient's lower dentition; wherein the first repositioning jaw element extends across an occlusal plane of the patient's upper dentition and the patient's lower dentition; and wherein the second repositioning jaw element that extends from a surface of the second shell, wherein the second repositioning jaw element extends across the occlusal plane of the patient's upper dentition and the patient's lower dentition; wherein the first interfacing surface and the second interfacing surface are positioned to interface with one another as the patient moves to a fully engaged sagittal jaw position of the patient's upper dentition and the patient's lower dentition in a manner to reposition the patient's jaw.

8 . The removable dental appliance of claim 7 , wherein the first repositioning jaw element and the second repositioning jaw element extend from an occlusal surface of the first shell and the second shell.

9 . The method of claim 7 , wherein the first repositioning jaw element and the second repositioning jaw element extend from at least one of a buccal surface and a lingual surface of the first shell and the second shell.

10 . The method of claim 7 , wherein the first repositioning jaw element and the second repositioning jaw element include a top groove on a top surface of the repositioning jaw elements and a plurality of side grooves on side surfaces of the repositioning jaw elements.

11 . The method of claim 10 , wherein the side grooves include coronal-apical grooves positioned at interproximal regions of at least one tooth of the plurality of teeth that the repositioning jaw elements extend from.

12 . The method of claim 7 , wherein the first repositioning jaw element and the second repositioning jaw element include a slant that has a higher coronal-apical height of the repositioning jaw elements in a mesial direction of the repositioning jaw elements than a coronal-apical height of the repositioning jaw elements in a distal direction.

13 . The method of claim 7 , wherein:
the first surface of the first repositioning jaw element includes a slanted surface on a mesial-facing surface of the first repositioning jaw element; and the second surface of the second repositioning jaw element includes a slanted surface on a distal-facing surface of the second repositioning jaw element.

14 . The method of claim 7 , wherein:
the repositioning jaw elements include a structure to indicate to the patient that the patient has positioned the first and second repositioning jaw elements of the first shell and second shell in the fully engaged sagittal jaw position.

15 . The method of claim 7 , wherein:
the first repositioning jaw element and the second repositioning jaw element are positioned to interface as the patient moves to the fully engaged sagittal jaw position of the patient's upper dentition and the patient's lower dentition in a manner to reposition the patient's jaw in an anteroposterior plane with respect to the jaw of the patient.

16 . The method of claim 7 , wherein the treatment plan comprises a plurality of stages to move the teeth of the patient's dentition from a first arrangement towards a second arrangement.

17 . The method of claim 7 , wherein separating occlusal surfaces includes separating occlusal surfaces to a threshold distance to prevent an occlusal surface of the first shell from contacting an occlusal surface of the second shell.

18 . The method of claim 1 , wherein the dental appliance is a first dental appliance of a series of dental appliances designed to incrementally implement a treatment plan,
the first shell having first attachment elements to retain the first shell on the patient's upper dentition, and the first shell having the first repositioning jaw element extending therefrom, the second shell having second attachment areas to receive and engage with second attachment elements to retain the second shell on the patient's lower dentition, and the second shell having the second repositioning jaw element extending therefrom, the first repositioning jaw element and the second repositioning jaw element of the first dental appliance have a first jaw
