Abstract

Methods and systems for taking images of a patient's teeth for tracking a progress of an orthodontic procedure. The methods and systems include a mobile device holder with one or more adjustable stops for providing a compressive force on a mobile device placed therein; a cheek retractor coupled to the mobile device holder; and a user interface on the mobile device indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.

Claims (36)

1. A system for taking images of a patient's teeth for tracking a progress of an orthodontic procedure, the system comprising:

a mobile device holder comprising one or more adjustable stops configured to provide a compressive force on a mobile device placed in the mobile device holder in order to prevent movement of the mobile device within the holder;

a cheek retractor coupled to the mobile device holder;

a non-transitory computing device readable medium having executable instructions that are executed by a processor to cause the mobile device to perform a method comprising:

providing, via the mobile device, a user interface; and

outputting an indicator, from the user interface, indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.

2. The system of claim 1 , wherein the one or more adjustable stops have a plastic material and a rubber and wherein the rubber provides friction to assist in preventing movement of the mobile device.

3. The system of claim 1 , wherein the one or more adjustable stops are configured to be horizontally adjustable to accommodate mobile devices of different sizes.

4. The system of claim 1 , wherein performing the method further comprises determining, based on a received input from the camera of the mobile device, whether the mobile device is positioned in the correct position or orientation with respect to the patient's teeth.

5. The system of claim 4 , wherein performing the method further comprises generating an instruction to the patient to change a position or orientation of the mobile device when the mobile device is determined to be in an incorrect position or orientation.

6. The system of claim 1 , wherein performing the method further comprises modifying a flash setting of the camera prior to capture of the one or more visual images of the teeth.

7. The system of claim 1 , wherein the user interface is configured to be presented to the patient off a reflective surface.

8. The system of claim 1 , wherein the cheek retractor comprises a first lip holder and a second lip holder.

9. The system of claim 1 , wherein taking the one or more visual images of the exposed teeth using the camera of the mobile device comprises taking one or more photographs.

10. The system of claim 1 , wherein taking the one or more visual images of the exposed teeth using the camera of the mobile device comprises taking one or more videos.

11. The system of claim 1 , wherein a position of the mobile device relative to the cheek retractor is adjustable by adjusting the mobile device holder.

12. The system of claim 11 , wherein the position of the mobile device relative to the cheek retractor is adjustable by adjusting an adjustment mechanism coupled to an arm of the mobile device holder, and wherein the arm of the mobile device holder is configured to attach to the cheek retractor.

13. A method of taking images of a patient's teeth for tracking a progress of an orthodontic procedure, the method comprising:

providing a mobile device holder and a cheek retractor, wherein the mobile device holder is coupleable to the cheek retractor, and wherein the mobile device holder is configured to hold a mobile device and includes an adjustable stop to provide a compressive force on the mobile device to secure the mobile device to the mobile device holder, wherein the cheek retractor is configured to be worn in a mouth of the patient and to position the mobile device relative to the patient's teeth;

providing, via a mobile device held in the mobile device holder, a user interface for taking images of the patient's teeth; and

displaying an indicator on the user interface indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.

14. The method of claim 13 , wherein the adjustable stop comprises a plastic material and a rubber, and wherein the rubber provides friction to assist in preventing movement of the mobile device.

15. The method of claim 13 , wherein the adjustable stop is configured to be adjusted by horizontally adjusting the adjustable stop to accommodate the mobile device.

16. The method of claim 13 , further comprising determining, based on a received input from the camera of the mobile device, whether the mobile device is positioned in the correct position or orientation with respect to the patient's teeth.

17. The method of claim 16 , further comprising generating an instruction to the patient to change a position or orientation of the mobile device when the mobile device is determined to be in an incorrect position or orientation.

18. The method of claim 13 , further comprising modifying a flash setting of the camera prior to capture of the one or more visual images of the teeth.

19. The method of claim 13 , wherein taking the one or more visual images of the exposed teeth using the camera of the mobile device comprises taking one or more photographs.

20. The method of claim 13 , wherein taking the one or more visual images of the exposed teeth using the camera of the mobile device comprises taking one or more videos.

21. The method of claim 13 , further comprising transmitting the one or more visual images of the exposed teeth for tracking the progress of the orthodontic procedure of the patient by a treatment professional.

22. A method of taking images of a patient's teeth for tracking a progress of an orthodontic procedure, the method comprising:

placing a mobile device, having a user interface, in a mobile device holder coupled to a cheek retractor;

adjusting an adjustable stop of the mobile device holder to provide a compressive force on the mobile device to secure the mobile device to the mobile device holder;

positioning the cheek retractor coupled to the mobile device holder against a cheek of a patient;

while engaging a cheek of the patient's teeth with the cheek retractor, moving the mobile device holder based on an indicator displayed on the user interface indicating whether the mobile device holder is in a correct position relative to the patient's teeth while taking one or more visual images of the exposed teeth using a camera of the mobile device.

23. The method of claim 22 , further comprising adjusting a position or orientation of the mobile device holder in response to an instruction via the user interface to change a position or orientation of the mobile device when the mobile device is determined to be in an incorrect position or orientation.

24. The method of claim 22 , further comprising transmitting the one or more visual images of the exposed teeth for tracking the progress of the orthodontic procedure of the patient by a treatment professional.
