Abstract: Systems and methods of simulating, modeling, and validating orthodontic treatment are disclosed. The method may include designing an orthodontic treatment system or force system, generative a displacement field between a first position of a patient's teeth and a second position, modeling the three-dimensional force-displacement model generated by the treatment system or force system, and validating the treatment system or force system. The methods disclosed herein may be iterated to optimize the orthodontic force system or treatment system.

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: Computer-implemented methods and systems for designing oral appliances. These methods and systems may include receiving patient data and a treatment plan (including a proposed one or more dental appliances), and determining, using the patient data and the treatment plan, an improved appliance design for treating the patient. These methods and systems may include evaluating the appliance design based on simulation and finalizing the appliance design based on the evaluation.

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: 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.

Abstract: A system and method for determining a center of resistance of a tooth may include receiving a 3D digital representation of an initial arrangement and a final arrangement of a patient's teeth and determining a 3D treatment plan. The 3D treatment plan may include a plurality of 3D stages for rearranging the teeth from the initial arrangement toward the final arrangement. The method may also include determining, in accordance with the 3D treatment plan, an intended movement of the teeth for each of the stages and deriving, using a 3D resistance model, an applied force system for achieving the intended movement of the teeth for each of the stages. The method may also include deriving 3D geometries of oral appliances for the stages in response to the applied force system. Various other systems and methods are also disclosed.

Abstract: Methods and systems for analysis of dental attachments. The dental attachments may be used in conjunction with a dental aligner worn by the patient to move the patient's teeth in accordance with a clinical treatment plan. A series of images may be taken while the patient is wearing the dental aligner. The series of images may be analyzed to confirm that the dental attachment(s) are present and bonded on the patient's tooth/teeth. Additionally or alternatively, the series of images may be analyzed to assess an interaction between the dental aligner and the attachment(s) bonded on the patient's tooth/teeth to determine if the attachment(s) have a defect. An indication of the status of the attachment(s) may be output to a user.
