Abstract

Systems and methods for conducting intraoral scans of a mouth of a user include conducting, using an intraoral scanner at an intraoral scanning site, an intraoral scan of a mouth of a user based on determining that one or more teeth of the user are not being repositioned according to an initial treatment plan designed to reposition the one or more teeth of the user using a first plurality of aligners. The intraoral scan generates three- dimensional data of the mouth of the user. A corrective treatment plan is generated by a treatment plan computing system based on the three-dimensional data. A second plurality of aligners are produced at a fabrication site based on the corrective treatment plan. The second plurality of aligners are specific to the user and configured to reposition the teeth of the user according to the corrective treatment plan.

Claims (20)

WHAT IS CLAIMED IS:
1. A method comprising: conducting, using an intraoral scanner at an intraoral scanning site, an intraoral scan of a mouth of a user based on determining that one or more teeth of the user are not being repositioned according to an initial treatment plan designed to reposition the one or more teeth of the user using a first plurality of aligners, the intraoral scan generating three-dimensional data of the mouth of the user; generating, by a treatment plan computing system, a corrective treatment plan for the user based on the three-dimensional data of the mouth of the user; producing, at a fabrication site, a second plurality of aligners based on the corrective treatment plan, the second plurality of aligners specific to the user and being configured to reposition the one or more teeth of the user in accordance with the corrective treatment plan; and providing the second plurality of aligners to the user.
2. The method of claim 1, wherein the initial treatment plan is based on initial three-dimensional data obtained from scanning dental impressions of the mouth of a user.
3. The method of claim 1, wherein the initial treatment plan is based on initial three-dimensional data obtained from conducting an initial intraoral scan of the mouth of the user.
4. The method of claim 1, further comprising providing the corrective treatment plan to a dental or orthodontic professional for review.
5. The method of claim 4, further comprising receiving an approval of the corrective treatment plan by the dental or orthodontic professional, wherein the approval is received without the dental or orthodontic professional physically seeing the user in person.
6. The method of claim 5, wherein producing the second plurality of aligners is responsive to receiving the approval.
7. The method of claim 1, wherein determining that the one or more teeth of the user are not being repositioned according to the initial treatment plan is based on information received from the user.
8. The method of claim 7, wherein the information includes an indication from the user that the user is unsatisfied with the initial treatment plan.
9. The method of claim 7, wherein the information includes an indication from the user that at least one aligner of the first plurality of aligners does not fit or is uncomfortable.
10. The method of claim 7, further comprising providing a message to the user requesting the user to provide the information.
11. The method of claim 1 , further comprising receiving compliance check information from the user indicating that the user correctly followed the initial treatment plan.
12. The method of claim 11, further comprising providing a financial incentive to the user responsive to the user having correctly followed the initial treatment plan.
13. The method of claim 1, further comprising providing, responsive to determining that the one or more teeth of the user are not being repositioned according to the initial treatment plan, the user scheduling information regarding scheduling an appointment at the intraoral scanning site to undergo the intraoral scan.
14. The method of claim 1, wherein generating the corrective treatment plan comprises manipulating, by the treatment plan computing system, one or more teeth in the three-dimensional data of the mouth of the user from a starting position at the time of the intraoral scan to an ending position.
15. The method of claim 1, wherein producing the second plurality of aligners comprises: generating a plurality of molds of a dentition of the user at at least a starting position and an ending position according to the corrective treatment plan, wherein each mold of the plurality of molds correspond with a specific step of the corrective treatment plan; and thermoforming a material to each of the molds to produce the second plurality of aligners.
16. A system comprising: a communications system configured to communicate with a user regarding an initial treatment plan designed to reposition one or more teeth of the user using a first plurality of aligners, the communication with the user indicating that the one or more teeth of the user are not being repositioned according to the initial treatment plan; an intraoral scanning site comprising an intraoral scanner configured to conduct an intraoral scan of a mouth of the user to generate three-dimensional data; a treatment planning computing system configured to generate a corrective treatment plan for the user based on the three-dimensional data; and a fabrication system comprising manufacturing equipment configured to produce a second plurality of aligners based on the corrective treatment plan data, the second plurality of aligners specific to the user and being configured to reposition the one or more teeth of the user in accordance with the corrective treatment plan.
17. The system of claim 16, wherein the initial treatment plan is based on initial three-dimensional data obtained from at least one of scanning dental impressions of the mouth of a user and conducting an initial intraoral scan of the mouth of the user.
18. The system of claim 16, wherein the communications system is configured to: determine, based on the communication with the user, whether the user correctly followed the initial treatment plan; and provide a financial incentive to the user responsive to determining that the user correctly followed the initial treatment plan, wherein the financial incentive is a reduction in cost of the second plurality of aligners.
19. A method comprising: conducting, using an intraoral scanner at an intraoral scanning site, an intraoral scan of a mouth of a user to generate three-dimensional data of the mouth of the user, the intraoral scan conducted based on information provided by the user, the information at least one of indicating that the user is unsatisfied with an initial treatment plan designed to reposition one or more teeth of the user using a first plurality of aligners, indicating that at least one aligner of the first plurality of aligners does not fit or is uncomfortable, and indicating that the one or more teeth of the user are not being repositioned according to the initial treatment plan; generating, by a treatment plan computing system, a corrective treatment plan for the user based on the three-dimensional data of the mouth of the user; providing the corrective treatment plan to a dental or orthodontic professional for review; receiving an approval of the corrective treatment plan by the dental or orthodontic professional, wherein the approval is received without the dental or orthodontic professional physically seeing the user in person; producing, at a fabrication site, a second plurality of aligners based on the corrective treatment plan, the second plurality of aligners specific to the user and being configured to reposition the one or more teeth of the user in accordance with the corrective treatment plan; and providing the second plurality of aligners to the user.
20. The method of claim 19, wherein the information includes photographs of the mouth of the user taken at various angles, at least one of the photographs having been taken with a dental appliance positioned at least partially within the mouth of the user, the dental appliance configured to hold open the userâ s upper and lower lips simultaneously to permit visualization of the userâ s teeth.
