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, the compliance signal including an electronic representation of the one or more physical properties of the oral appliance, 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, and providing one or more compliances indicators based on the one or more patient compliance factors, the one or more compliance indicators providing a basis to indicate the extent of compliance.

Abstract: Detection of placement of dental aligners in patient mouth on teeth for indication of wearing compliance. Described herein are apparatuses and methods for detecting wearing, including compliance. In some variations these apparatuses and methods may include a sensor configured to detect deflection of the one or more deflectable structures. In some variations, these apparatuses and methods may include a proximity sensor coupled to the appliance shell and configured to generate sensor data when in proximity with intraoral tissue.

Abstract: Apparatuses and methods for performing orthodontic treatment planning are provided. Virtual/Augmented Reality devices can be used to virtually manipulate patient's teeth, modify virtual models of the patient's teeth, analyze the fit of a dental appliance on the patient's teeth, analyze the position of attachment sites for dental appliances, and provide overlays showing forces applied to the patient's teeth. The VR/AR devices can be used by physicians and/or the patient to provide and display treatment planning.

Abstract: A dental appliance includes an interior shape that substantially conforms to a dental arch of a patient, a hollow portion forming a cavity, and an object bonded to the dental appliance and inserted into the cavity. The object provides structural strength to the dental appliance at a location of the hollow portion and does not interfere with a fit of the dental appliance onto the dental arch of the patient.

Abstract: A plastic shell such as an orthodontic aligner has an interior shape that substantially conforms to a current or future dental arch of a patient. The plastic shell includes a hollow feature comprising a cavity. The plastic shell additionally includes an object inserted into the cavity, wherein the object provides structural strength to the plastic shell at a location of the hollow feature and does not interfere with a fit of the plastic shell onto the dental arch of the patient.

Abstract: Embedded sensors and onboard or off-board processing in an aligner case can detect aligner material and/or quality. Material detection can be used for counterfeit detection, or to trigger material specific events. Quality detection can include detection of common aligner failures or defects. A case for a dental appliance may include a tray for supporting the dental appliance, a cover coupled to the tray, and at least one sensor to detect a deformation of the dental appliance. A case for a dental appliance may include a tray for housing the dental appliance, a cover coupled to the tray, and at least one sensor configured to detect a change in material of the dental appliance.

Abstract: Methods and systems for producing orthodontic appliances are provided herein utilizing iterative modeling techniques to increase the efficiency and efficacy of said appliances. Further disclosed herein are the orthodontic appliances fabricated from such methods.

Abstract: Methods and apparatuses for monitoring either or both the performance of an orthodontic appliance for repositioning a patient's teeth and/or the user compliance in wearing the appliance using a biosensor. The apparatuses described herein may include one or more sensors, including biosensors, electrical sensors, or both, configured to generate sensor data related to user compliance and/or repositioning of the patient's teeth by an orthodontic appliance.

Abstract: Orthodontic appliances, including in particular, aligners, that are configured to deliver energy (e.g., light and/or heat and/or electrical energy) to regions of a patient's dental arch to aid in an orthodontic treatment. For example, described herein are systems and methods of embedding light emitting diodes (LEDs), heating elements and/or energy emitting elements in an orthodontic device for accelerating an orthodontic treatment. Method of modifying a dental arch using an orthodontic appliance that delivers local light and/or heat and/or electrical energy are also described.

Abstract: Improved systems, methods, and devices for treating sleep apnea are provided herein. In one aspect, an intraoral appliance for treating sleep apnea in a patient comprises an appliance shell comprising a plurality of cavities shaped to receive teeth of a jaw of the patient. The appliance shell can comprise an advancement structure arranged to interact with an opposing jaw of the patient so as to displace the lower jaw anteriorly relative to the upper jaw. The plurality of cavities can comprise cavity geometries shaped to reduce repositioning of one or more received teeth elicited by displacement of the lower jaw anteriorly relative to the upper jaw.
