Abstract

The present disclosure describes devices, systems, and methods for monitoring use of an oral appliance in an oral cavity using extra-oral sensor(s). One method includes sensing one or more physical properties of an oral appliance using an extra-oral sensor, providing a compliance signal from the extra-oral sensor, identifying one or more patient compliance factors based on the compliance signal, the one or more patient compliance factors providing a basis to identify an extent of compliance of usage of the oral appliance with an orthodontic treatment plan, determining the extent of compliance, and outputting the extent of compliance.

First claim

What is claimed is:

1. A storage case for an oral appliance, the storage case comprising:
a body having a shape and size for storing the oral appliance; and
a compliance indicator system including:
a sensor configured to sense one or more physical properties of the oral appliance and to provide a compliance signal that is associated with a time that the oral appliance is within the storage case;
one or more processors;
memory coupled to the one or more processors, the memory comprising computer-program instructions that, when executed by the one or more processors, cause the compliance indicator system to:
identify one or more patient compliance factors based on the compliance signal, the one or more patient compliance factors providing a basis to determine an extent of compliance of usage of the oral appliance with an orthodontic treatment plan specific to a patient;
determine the extent of compliance of the patient based on the orthodontic treatment plan specific to the patient and the one or more patient compliance factors; and
output the extent of compliance of the patient for one or more stages of the orthodontic treatment plan.

2. The storage case of claim 1 , wherein the compliance signal indicates whether the oral appliance was in the storage case over a threshold period of time.

3. The storage case of claim 1 , wherein the compliance indicator system further comprises a power supply.

4. The storage case of claim 3 , wherein compliance indicator system includes a switch mechanism configured to turn the power supply on or off.

5. The storage case of claim 3 , wherein the compliance indicator system is configured to determine compliance based on a power level of the power supply compared to a pretreatment power level or based on a predetermined threshold power level.

6. The storage case of claim 1 , wherein the compliance indicator system further comprises a light source configured to generate light, wherein the sensor is an imaging sensor configured to sense diminished or blockage of light generated by the light source.

7. The storage case of claim 1 , wherein the compliance indicator system includes a clock circuit configured to measure the time that the oral appliance is within the storage case.

8. The storage case of claim 1 , wherein the compliance indicator system further comprises a transmitter to transmit compliance data to a remote device.

9. The storage case of claim 1 , further comprising a near field communication component that is configured to transfer energy from a device that comes within the range of a near field antenna of the near field communication component to a power supply of the storage case.

10. The storage case of claim 1 , wherein the sensor is configured to be activated by a latch that keeps the storage case closed.

11. The storage case of claim 1 , wherein the compliance indicator system further comprises an alarm that is configured to activate when the time that the oral appliance is within the storage case is greater than a threshold time period.

12. The storage case of claim 1 , wherein the computer-program instructions is configured to identify the one or more patient compliance factors based on the compliance signal that is specific to one or more of a plurality of different stages of the treatment plan.

13. The storage case of claim 1 , wherein the computer-program instructions is configured to output the extent of compliance by indicating to the patient whether or not the patient is complying with the treatment plan.

14. The storage case of claim 1 , wherein the treatment plan requires the patient to wear the oral appliance for a specified circumstance.

15. The storage case of claim 1 , wherein the treatment plan specifies an amount of time per day for each stage that the oral appliance is to be worn.

16. A method of measuring an extent of compliance of usage of an oral appliance, the method comprising:
generating a compliance signal from a sensor of a storage case for the oral appliance, the sensor configured to sense one or more physical properties of the oral appliance associated with a time that the oral appliance is within the storage case;
wherein the sensor is part of a compliance indicator system integrated into the storage case, the compliance indicator system comprising:
one or more processors;
memory coupled to the one or more processors, the memory comprising computer-program instructions that, when executed by the one or more processors, cause the compliance indicator system to:
identify one or more patient compliance factors based on the compliance signal, the one or more patient compliance factors providing a basis to determine an extent of compliance of usage of the oral appliance with an orthodontic treatment plan specific to a patient;

determining the extent of compliance of the patient based on the orthodontic treatment plan specific to the patient and the one or more patient compliance factors; and
outputting the extent of compliance of the patient for one or more stages of the treatment plan.

17. The method of claim 16 , wherein the one or more patient compliance factors is determined based at least in part on a power level of the power supply compared to a pretreatment power level or based on a predetermined threshold power level.

18. The method of claim 16 , wherein outputting further comprises transmitting the extent of compliance from the storage case to a remote device.

19. The method of claim 16 , wherein the computer-program instructions is configured to identify one or more patient compliance factors specific to one or more of a plurality of different stages of the treatment plan.

20. The method of claim 16 , wherein outputting the extent of compliance for one or more stages of the treatment plan comprises outputting an indicator that indicates to the patient whether or not the patient is complying with the treatment plan.

21. The method of claim 16 , wherein determining the extent of compliance comprises determining the extent of compliance in a remote computing device.

22. The method of claim 16 , wherein the treatment plan requires the patient to wear the oral appliance for a specified circumstance.

23. The method of claim 16 , wherein the treatment plan specifies an amount of time per day for each stage that the oral appliance is to be worn.
