Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. The palatal expanders may include tooth engagement regions connected by a palatal region that is configured to apply force between the tooth engagement regions. At least a portion of the palatal region may be configured to have a clearance from the patient's mid-palatal region when the palatal expander is worn by the patient. The clearance between the palatal region and the patient's palate may decrease from the patient's mid-palatal region laterally toward the tooth engagement regions.

Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of making them. The apparatuses may include a pair of tooth engagement regions connected by a palatal region. A detachment region on at least one of the tooth engagement regions may be defined by one or more first vertical cut-out regions extending from a bottom of a buccal side toward an occlusal side of the tooth engagement region. The buccal side may be more flexible than the occlusal side so that the detachment region flexes when a removal force to release the palatal expander apparatus from the patient's palate is applied to the detachment region.

Abstract: Embodiments relate to an aligner breakage solution that tests damage to an aligner using machine learning. A method includes of training a machine learning model to predict damage to an orthodontic aligner includes gathering a training dataset comprising digital designs for a plurality of orthodontic aligners, wherein each digital design is associated with a respective orthodontic aligner of the plurality of orthodontic aligners, and wherein each digital design comprises metadata indicating whether the associated respective orthodontic aligner was damaged during manufacturing of the associated respective orthodontic aligner. The method further includes training the machine learning model using the training dataset, wherein the machine learning model is trained to process data from a digital design for an orthodontic aligner and to output a probability that the orthodontic aligner associated with the digital design will be damaged during manufacturing of the orthodontic aligner.

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: Releasable and removable palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These releasable palatal expanders are adapted for ease in removal by the patient or caregiver, and may include a breach region configured to predictably bend or break when a pulling force is applied. The palatal expander apparatuses described herein may include one or more locks for locking the palatal expander onto the patient's teeth. The lock(s) may be unlocked to release the palatal expander from the teeth. A lock may include a control for manually unlocking the lock. Unlocking the locks may allow the palatal expander to automatically disengage from the patient's teeth.

Abstract: Embodiments relate to an aligner breakage solution that tests progressive damage to an aligner. A method includes gathering a digital model representing an aligner for a dental arch of a patient, and simulating progressive damage to the aligner. Simulating progressive damage for a region of the aligner comprises simulating, using at least the digital model, a sequence of loads on the aligner, determining an amount of damage to the region of the aligner for each load, and after each simulation of a load on the aligner, updating the digital model based on the amount of damage to the region of the aligner. The method further includes determining whether a damage criterion is satisfied for at least one region of the aligner and determining whether to implement one or more corrective actions for the aligner.
