Abstract: Apparatuses and methods for monitoring the performance of an orthodontic appliance for repositioning a patient's teeth. An orthodontic appliance may include a plurality of teeth receiving cavities shaped to reposition the patient's teeth from an initial arrangement towards a target arrangement, and one or more sensors configured to determine tooth movement (based on position and/or orientation) and/or forces applied to the teeth. The sensor may be distributed between attachments and aligners that mate with the attachments.

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: 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, 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 compliance 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: Methods and apparatuses for 3D imaging to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.

Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).

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 for designing a palatal expander. Methods may include forming a digital model of a palatal region and tooth engagement regions. Methods may include forming attachment regions on buccal sides of the tooth engagement regions, the attachment regions shaped and sized to engage with attachments bonded to a patient's teeth. Methods may also include forming at least one breach region corresponding to a thinned region of the palatal expander that extends anteriorly to posteriorly in the palatal region or an occlusal portion of one or both of the tooth engagement regions. The breach region may be configured to breach or bend when a pulling force is applied to one or both of the tooth engagement regions such that the attachment regions are detached from respective attachments.
