Abstract
Method and Apparatuses for monitoring progress of an orthodontic treatment plan and automatically or semi-automatically modifying the orthodontic treatment plan. The orthodontic treatment plan may be monitored by sensors on one or more appliance in the treatment plan, and may be monitored if the sensed data deviates from the expected treatment plan.
Claims19
A method of modifying an orthodontic treatment plan, the method comprising:
- receiving sensor data from one or more sensors of an orthodontic appliance;
- determining force acting on teeth and mechanical impedance of the teeth based on the sensor data;
- estimating tooth movement based on the determined force acting on the teeth and mechanical impedance of the teeth;
- comparing the estimated tooth movement to an expected tooth movement from the treatment plan;
- and
- modifying the treatment plan if the estimated tooth movement is not within a predetermined range of the expected tooth movement from the treatment plan.
3 more elements
A method of modifying an orthodontic treatment plan, the method comprising:
- receiving sensor data from one or more sensors of an orthodontic appliance, the sensor data related to forces applied to one or more aligner attachments on a patient's teeth wherein receiving the sensor data from the one or more sensors includes triggering a switch in the orthodontic appliance when one or more electrodes contact the one or more aligner attachments on the patient's teeth;
- determining an expected one or more force values or a range of expected force values for the one or more sensors from the orthodontic treatment plan;
- comparing the determined expected one or more force values to the sensor data for each of the one or more sensors;
- and
- modifying the treatment plan if the sensor data does not match the determined expected one or more force values.
