Methods of manufacturing dental aligners
Method of manufacturing a series of aligners for an orthodontic and/or dental treatment of a patient's teeth. In particular, described herein are methods of manufacturing a series of aligners that includes displaying images of the patient's teeth at the final stages for a subset of the treatment plans from the array of treatment plans in a manner that allows the user to select between the different treatment plans in order to select a treatment plan for fabrication.
1. A method of manufacturing a series of aligners for a patient's teeth, the method comprising:
receiving, in a processor, a model of the patient's teeth and an array of treatment plans specific to the patient's teeth, wherein each treatment plan in the array describes a set of sequential stages for orthodontic movement of the patient's teeth, including a final stage, further wherein the final stages of the treatment plans within the array of treatment plans are different;
displaying, on a screen, images of the patient's teeth at the final stages for a subset of the treatment plans from the array of treatment plans;
receiving, from a user, a selection to modify one or more treatment parameters for the subset of the treatment plans;
displaying, on the screen, one or more modified images of the patient's teeth at the final stages based on the received selection to modify the one or more treatment parameters for the subset of the treatment plans;
receiving, from the user, a selection of two or more treatment plans from the subset of the treatment plans selected using one or more controls on the screen;
displaying, to the patient, the two or more treatment plans from the subset of the treatment plans; and
fabricating the series of aligners based on a selected one of the two or more displayed treatment plans selected by the patient.
2. The method of claim 1 , wherein at least three of the subset of the treatment plans have different numbers of sequential stages.
3. The method of claim 1 , further comprising transmitting the model of the patient's teeth to a remote site.
4. The method of claim 1 , wherein displaying the two or more treatment plans comprises displaying annotations describing changes in the final stage of each of the two or more treatment plans compared to the model of the patient's teeth.
5. The method of claim 4 , wherein the annotations comprise one or more of: changes in a malocclusion, changes in the patient's bite, and changes in an upper and/or lower crowding.
6. The method of claim 1 , wherein displaying, to the patient, the two or more treatment plans from the subset of the treatment plans comprises displaying sequential stages of the two or more treatment plans.
7. The method of claim 1 , further comprising switching, in real time, one or more of the images of the patient's teeth at the final stages of the subset for different treatment plans with an image of a final stage of one or more other treatment plans from the array of treatment plans, based on one or more user-selected controls on the screen.
8. The method of claim 1 , wherein the two or more treatment plans from the subset of the treatment plans comprise two or more treatment plans having different numbers of sequential stages.
9. The method of claim 1 , wherein the one or more treatment parameters include whether to use attachments, whether to use interproximal reduction (IPR), changing a tooth number, adding, removing and/or moving attachments, adding, removing and/or modifying IPR between selected teeth, and/or adding and/or removing a pontic.
10. The method of claim 1 , further comprising:
determining that the modifications of the one or more treatment parameters requires recalculating one or more treatment plans of the array of treatment plans;
transmitting the modifications of the one or more treatment parameters to a treatment planning subsystem to generate one or more additional treatment plans based on the modifications; and
displaying, on the screen, images of the patient's teeth at the final stages for a second subset of the treatment plans from the one or more additional treatment plans, wherein the selection of two or more treatment plans are from the second subset of the treatment plans.
11. A method of manufacturing a series of aligners for a patient's teeth, the method comprising:
transmitting a model of the patient's teeth to a remote site;
receiving, from the remote site, an array of treatment plans specific to the patient's teeth, wherein each treatment plan in the array describes a set of sequential stages for orthodontic movement of the patient's teeth, including a final stage, further wherein at least three of the treatment plans have different numbers of sequential stages, and further wherein the final stages of the treatment plans within the array of treatment plans are different;
displaying, on a screen, images of the patient's teeth at the final stages for a first subset of the treatment plans from the array of treatment plans;
receiving, from a user, a selection to modify one or more treatment parameters for the first subset of the treatment plans;
displaying, on the screen, one or more modified images of the patient's teeth at the final stages based on the received selection to modify the one or more treatment parameters for the first subset of the treatment plans;
receiving, from the user, a selection of two or more treatment plans from the first subset of the treatment plans using one or more controls on the screen;
displaying, to the patient, the two or more treatment plans and annotations describing changes in the final stage of each of the two or more treatment plans compared to the model of the patient's teeth; and
fabricating the series of aligners based on a selected one of the two or more displayed treatment plans selected by the patient.
12. The method of claim 11 , wherein the annotations comprise one or more of: changes in a malocclusion, changes in the patient's bite, and changes in an upper and/or lower crowding.
13. The method of claim 11 , wherein displaying, to the patient, the two or more treatment plans from the first subset of the treatment plans comprises displaying corresponding numbers of sequential stages.
14. The method of claim 11 , further comprising switching, in real time, one or more of the images of the patient's teeth at the final stages of the first subset for different treatment plans with an image of the final stage of one or more other treatment plans from the array of treatment plans, based on one or more user-selected controls on the screen.
15. The method of claim 11 , wherein the two or more treatment plans from the first subset of the treatment plans comprise two or more treatment plans having different numbers of sequential stages.
16. A method of manufacturing a series of aligners for a patient's teeth, the method comprising:
receiving, in a processor, an array of treatment plans specific to the patient's teeth, wherein each treatment plan in the array describes a set of sequential stages for orthodontic movement of the patient's teeth, including a final stage, further wherein at least three of the treatment plans have different numbers of sequential stages, and further wherein the final stages of the treatment plans within the array of treatment plans are different;
displaying, on a screen, images of the patient's teeth at the final stages for a first subset of the treatment plans from the array of treatment plans;
receiving, from a user, a selection to modify one or more treatment parameters for the first subset of the treatment plans;
determining that the modifications of the one or more treatment parameters requires recalculating one or more treatment plans of the array of treatment plans;
transmitting the modifications of the one or more treatment parameters to a treatment planning subsystem to generate one or more additional treatment plans based on the modifications;
displaying, on the screen, images of the patient's teeth at the final stages for a second subset of the treatment plans from the one or more additional treatment plans;
receiving, from the user, a selection of two or more treatment plans from the second subset of the treatment plans using one or more controls on the screen;
displaying, to the patient, the two or more treatment plans; and
fabricating the series of aligners based on a selected one of the two or more displayed treatment plans selected by the patient.
