Invisible dental brace with pressure-sensitive sensors

An invisible dental brace with pressure-sensitive sensors, including:

• a brace body (101), including at least one cavity (1011) for being attached to at least one corresponding tooth (2011) of an orthodontic patient and repositioning the at least one corresponding tooth from an initial position towards a target position according to a prescribed plan of orthodontic treatment;
• at least one pressure-sensitive sensor (102), arranged on a buccal and/or lingual side of the at least one cavity, wherein the at least one pressure-sensitive sensor is configured to generate a sensor signal related to wearing time of the brace body and a force or pressure produced between each cavity of said at least one cavity and each tooth of said at least one corresponding tooth (2011), and/or configured to transmit the sensor signal (102S) wirelessly to a cloud database (103) for further analysis and for an orthodontic practitioner to modify the orthodontic treatment;
• a processor (104), coupled to the brace body (101) and configured to receive, store, and process the sensor signal (102S), wherein the processor generates a performance of the brace body (101) based on the sensor signal (102S) and transmits the performance wirelessly to the cloud database (103) for an orthodontic practitioner to modify the prescribed plan of orthodontic treatment;
• and
• a brace health monitoring module (120), having signal connection to or embedded in at least one of the processor and the cloud database, the brace health monitoring module analyzing the sensor signal (102S) to evaluate a health status of the pressure-sensitive sensor and/or the brace body, wherein the health status of the pressure-sensitive sensor is determined by at least one of operational integrity, calibration accuracy, and moisture ingress status of the pressure-sensitive sensor (102), and the health status of the brace body is determined by at least one of capacitance drift, and signal output drift of the pressure-sensitive sensor, wherein when the health status of the pressure-sensitive sensor and/or the brace body falls outside a predetermined acceptable range, a health alert is generated.
