Abstract

Systems and methods for providing orthodontic treatment may include identifying an orthodontic treatment plan for a patient's teeth, identifying a first batch of orthodontic appliances to implement a first phase of the orthodontic treatment plan, obtaining a digital representation of the patient's teeth during the first phase of the orthodontic treatment plan, determining, based on the digital representation, whether or not the patient's teeth accord with one or more customized treatment guidelines for the patient's teeth; identifying, based on a determination whether or not the patient's teeth accords with the one or more customized treatment guidelines, one or more tasks for administering a second phase of the treatment plan to the patient's teeth, and providing a set of orthodontic appliances to a dental practitioner.

Claims (48)

1. A computer-implemented method for managing delivery of an orthodontic treatment plan, the method comprising:

identifying an orthodontic treatment plan for a patient's teeth, the orthodontic treatment plan including specifying a first plurality of successive tooth arrangements to move the plurality of teeth from a first arrangement toward a second arrangement;

identifying a first batch of orthodontic appliances to implement a first phase of the orthodontic treatment plan;

generating one or more first treatment tasks to implement the first phase of the orthodontic treatment plan;

graphically representing treatment instructions for how to administer the one or more first treatment tasks;

obtaining a digital representation of the patient's teeth during the first phase of the orthodontic treatment plan;

segmenting the digital representation of the patient's teeth to create digital representations of individual teeth of the patient's teeth;

determining, using the digital representation, whether or not the patient's teeth accord with one or more customized treatment guidelines for the patient's teeth;

identifying, based on a determination whether or not the patient's teeth accords with the one or more customized treatment guidelines, one or more second tasks for administering a second phase of the treatment plan to the patient's teeth; and

prior to fabricating a first batch of orthodontic appliances, graphically representing, to a treating practitioner, treatment instructions for how to administer the one or more second treatment tasks.

2. The computer-implemented method of claim 1 , further comprising providing instructions to administer the first batch of the orthodontic appliances before the first phase.

3. The computer-implemented method of claim 1 , wherein the one or more tasks comprise:

making a determination whether the patient's teeth are progress tracking according to the first phase of the orthodontic treatment plan; and

identifying, based on a determination whether the patient's teeth are progress tracking according to the first phase, a second batch of orthodontic appliances to implement the second phase of the orthodontic treatment plan.

4. The computer-implemented method of claim 1 , wherein:

the one or more tasks comprise:

making a determination whether the patient's teeth are progress tracking according to the first phase of the orthodontic treatment plan; and

identifying, based on a determination whether the patient's teeth are progress tracking according to the first phase, a second batch of orthodontic appliances to implement the second phase of the orthodontic treatment plan; and

the method further comprises:

providing instructions to administer the first batch of the orthodontic appliances before a beginning of the first phase; and

providing instructions to administer the second batch of the orthodontic appliances after the beginning of the first phase.

5. The computer-implemented method of claim 1 , further comprising graphically representing the one or more customized treatment guidelines, the one or more tasks, or some combination thereof, to a user of a computing device.

6. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu displaying appointment information relevant to the appointment, the appointment information comprising at least a portion of the one or more customized treatment guidelines, the one or more tasks, or some combination thereof.

7. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu displaying appointment information, the appointment information guiding a practitioner to track progress of the treatment plan during the first phase.

8. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu displaying appointment information, the appointment information guiding a practitioner to order a second batch of orthodontic appliances to implement the second phase of the orthodontic treatment plan.

9. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu displaying appointment information, the appointment information guiding a practitioner to provide one or more refinements to the orthodontic treatment plan.

10. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu instructing administration of at least a portion of the treatment plan for the patient's teeth.

11. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu instructing administration of one or more of: interproximal reduction (IPR), attachment placement, attachment removal, or some combination thereof, for the patient's teeth.

12. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu instructing administration of attachment removal in order to perform a refinement of the treatment plan.

13. The computer-implemented method of claim 1 , further comprising graphically representing an appointment menu providing a future appointment having an appointment timing identified to coincide with a treatment event.

14.

15. The computer-implemented method of claim 1 , further comprising graphically representing a list of recommended tasks to be completed during a practitioner's appointment with the patient.

16. The computer-implemented method of claim 1 , wherein graphically representing treatment instructions for how to administer the one or more first treatment tasks includes graphical illustrations of a projected position of the patient's teeth during at least a portion of the first phase including annotations of locations for treatment on the graphical illustrations.

17. The computer-implemented method of claim 1 , further comprising graphically representing tasks for a plurality of appointments related to the treatment plan.

18. The computer-implemented method of claim 1 , wherein obtaining a digital representation of the patient's teeth during the first phase of the orthodontic treatment plan comprises one or more of: obtaining a scan of the patient's teeth, and obtaining a digitization of physical impressions of the patient's teeth.

19. The computer-implemented method of claim 1 , further comprising providing one or more of the first batch of appliances and the second batch of appliances to a treatment professional or to the patient.

20. A system comprising:

one or more processors;

memory storing computer-program instructions that, when executed by the one or more processors, cause the one or more processors to execute a computer-implemented method comprising:

identifying an orthodontic treatment plan for a patient's teeth, the orthodontic treatment plan including specifying a first plurality of successive tooth arrangements to move the plurality of teeth from a first arrangement toward a second arrangement;

identifying a first batch of orthodontic appliances to implement a first phase of the orthodontic treatment plan;

generating one or more first treatment tasks to implement the first phase of the orthodontic treatment plan;

graphically representing treatment instructions for how to administer the one or more first treatment tasks;

obtaining a digital representation of the patient's teeth during the first phase of the orthodontic treatment plan;

segmenting the digital representation of the patient's teeth to create digital representations of individual teeth of the patient's teeth;

determining, using the digital representation, whether or not the patient's teeth accord with one or more customized treatment guidelines for the patient's teeth;
