Treatment plan specific bite adjustment structures
A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. A first number of bite adjustment structures can be formed of a same material as the first shell, extending therefrom and designed to interface with teeth of a second jaw. The first number of bite adjustment structures can have a first shape and location specific to a first stage of the treatment plan. A second number of bite adjustment structures can be formed of a same material as the second shell, extending therefrom and designed to interface with teeth of the second jaw. The second number of bite adjustment structures can have a second shape and location, different than the first shape and location, specific to a second stage of the treatment plan.
1. A method, comprising:
positioning a plurality of digital bite adjustment structures on a corresponding plurality of digital teeth of a digital model of a first jaw at a first stage of a treatment plan;
configuring the digital bite adjustment structures to have a first shape and location specific to the first stage of the treatment plan designed to interface with teeth of a second jaw and including an edge where each respective digital bite adjustment structure meets a respective one of the digital teeth and to have a surface corresponding to an outer surface of a physical appliance;
adjusting the digital bite adjustment structures by changing the position of the plurality of digital bite adjustment structures on the corresponding plurality of digital teeth of the digital model of the first jaw at a second stage of the treatment plan; and
outputting the digital model of the first jaw for fabrication of physical appliances corresponding to the first jaw at the first and the second stages of the treatment, the appliances having cavities shaped to receive the teeth of the model and bite adjustment structures shaped according to the surface corresponding to the outer surface of a physical appliance.
2. The method of claim 1 , wherein the adjusting further comprises:
changing a shape of the plurality of digital bite adjustment structures on the corresponding plurality of digital teeth of the digital model of the first jaw.
3. The method of claim 1 , wherein the adjusting further comprises:
changing a location of the plurality of digital bite adjustment structures on the corresponding plurality of digital teeth of the digital model of the first jaw.
4. The method of claim 1 , wherein the adjusting further comprises:
changing an orientation of the plurality of digital bite adjustment structures on the corresponding plurality of digital teeth of the digital model of the first jaw.
5. The method of claim 1 , wherein the adjusting further comprises:
changing a size of the plurality of digital bite adjustment structures on the corresponding plurality of digital teeth of the digital model of the first jaw.
6. The method of claim 1 , wherein the corresponding plurality of digital teeth of the digital model are anterior digital teeth of the digital model.
7. The method of claim 6 , further comprising:
modeling a force to be applied to the plurality of digital bite adjustment structures by a user wearing a corresponding one of the physical appliances during the first stage of the treatment plan; and
adjusting a shape of the digital model of the first jaw at the first stage of the treatment plan such that the corresponding one of the physical appliances distributes a counterforce corresponding to the force to a number of posterior teeth of the user's first jaw with the corresponding one of the physical appliances is worn by the user.
8. The method of claim 1 , wherein the adjusting is made according to changes to the digital model of the first jaw between the first stage of the treatment plan and the second stage of the treatment plan.
9. The method of claim 3 , wherein the changing the location includes changing a vertical relationship between stages to correct for a deep bite.
10. The method of claim 9 , wherein changing the vertical relationship between stages includes progressively moving the location towards an incisal edge of a respective digital tooth.
11. The method of claim 1 , wherein adjusting the digital bite adjustment structures is to provide a disocclusion between posterior and/or anterior teeth.
12. The method of claim 3 , wherein changing the location is based on changes in intrusion or extrusion of the tooth or a corresponding tooth on an opposing jaw and/or movement of the tooth or a corresponding tooth on an opposing jaw.
13. A method, comprising:
receiving a digital model of a patient's teeth comprising a first jaw and a second jaw and including a deep bite malocclusion of the patient's teeth and in response to the receiving the digital model:
positioning a plurality of digital bite adjustment structures on a corresponding plurality of digital teeth of a digital model of a first jaw at a first stage of a treatment plan;
configuring the digital bite adjustment structures to have a first shape and location specific to the first stage of the treatment plan designed to interface with teeth of a second jaw, the digital bite adjustment structures including an edge where each respective digital bite adjustment structure meets a respective one of the digital teeth and to have a surface corresponding to an outer surface of a physical appliance;
adjusting the digital bite adjustment structures by changing a vertical position of the plurality of digital bite adjustment structures on the corresponding plurality of digital teeth of the digital model of the first jaw at a second stage of the treatment plan to aid in correcting the deep bite malocclusion; and
outputting the digital model of the first jaw for fabrication of physical appliances corresponding to the first jaw at the first and the second stages of the treatment plan, the appliances having cavities shaped to receive the teeth of the model and bite adjustment structures shaped according to the surface corresponding to the outer surface of a physical appliance.
14. The method of claim 13 , wherein changing the vertical position includes moving the digital bite adjustment structures towards an incisal edge of a respective digital tooth.
15. The method of claim 13 , wherein the adjusting is made according to changes to the digital model of the physical appliance for the first jaw between the first stage of the treatment plan and the second stage of the treatment plan.
16. The method of claim 13 , wherein adjusting the digital bite adjustment structures is to provide a disocclusion between posterior and/or anterior teeth.
17. The method of claim 13 , wherein changing the vertical position is based on changes in intrusion or extrusion of the tooth or a corresponding tooth on an opposing jaw and/or movement of the tooth or a corresponding tooth on an opposing jaw.
18. The method of claim 13 , wherein the adjusting further comprises:
changing an orientation of the plurality of digital bite adjustment structures on the corresponding plurality of digital tooth of the first jaw.
