Abstract: Methods for designing and fabricating palatal expanders by modeling expansion of the palatal region based on material properties for one or more regions of a maxillary jaw determined from a cone-beam computed tomography (CBCT) scan of the maxillary jaw and/or internal topological information for the maxillary jaw determined from the CBCT scan. Also described herein are series of palatal expanders having a sequence and configured to be sequentially worn by a patient to expand the patient's palate in which the left maxillary portion and the right maxillary portion are progressively separated relative to each other, and the thickness of the palatal region changes.

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: Apparatuses (e.g., distalizers) and methods for distalizing a subject's teeth while preventing or reducing undesirable tipping and/or rotation of the teeth. The distalizer apparatuses may include tooth engagement regions shaped to accommodate molars, canines and/or premolar teeth, may include a transpalatal region extending between engagement regions having an anterior edge that is posterior to a premolar region of the first tooth engagement region, and may include an attachment site for an elastic band on the outer buccal surface.

Abstract: According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.

Abstract: Described herein are attachments for an orthodontic appliance, such as an aligner, that include a base region configured to be rigidly mounted to a tooth surface and an interface surface region that is configured to engage with the orthodontic appliance, in which the base region and the interface surface region are movably connected. These attachments may be configured as force applying attachments and/or as force redirecting attachments. Also described herein are modular attachments.

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: Methods and apparatuses (including software) for optimizing dental treatment plans, including for optimizing the treatment plans using dental aligners. These methods and apparatuses may optimize a treatment plan by estimating a difference between a target set of tooth position and a predicted set of tooth positions using the treatment plan using a prediction network trained to use multiple translational and rotational directions for individual teeth as well as reaction forces on the individual teeth based on adjacent teeth.

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.
