摘要： 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.

摘要： Embodiments relate to an aligner breakage solution that tests damage to an aligner using machine learning. A method includes processing data from a digital design for an orthodontic aligner by a trained machine learning model and outputting, by the trained machine learning model, a probability that the orthodontic aligner associated with the digital design will be damaged during manufacturing of the orthodontic aligner. The method further includes making a comparison of the probability that the orthodontic aligner associated with the digital design will be damaged during manufacturing of the orthodontic aligner to a probability threshold and determining whether the orthodontic aligner is a high risk orthodontic aligner based on a result of the comparison. Responsive to determining that the orthodontic aligner is a high risk orthodontic aligner, the method includes performing at least one of a) a corrective action or b) selecting a manufacturing flow for high risk orthodontic aligners.

摘要： Embodiments relate to an aligner breakage solution that tests probability of aligner breakage at weak points. A method includes gathering a digital model representing an aligner for a dental arch of a patient, receiving material property information for a material to be used to manufacture the aligner, and analyzing one or more regions of the aligner. Analyzing a region of the aligner comprises simulating application of a load around the region, determining at least one of a stress, a strain or a strain energy density at the region, evaluating a strength of the aligner at the region, and determining whether the region satisfies a damage criterion based on the strength of the aligner at the region.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Palatal expander systems and methods. A palatal expander includes a palatal region connecting tooth engagement regions, where the palatal region is configured to apply a lateral force across a patient's palate when the tooth engagement regions are worn over the patient's teeth. Attachment regions on buccal sides of the tooth engagement regions are shaped and sized to engage with dental attachments bonded to the patient's teeth. At least one breach region corresponding to a thinned region of the palatal expander extends anteriorly to posteriorly in the palatal region or an occlusal portion of one or both of the tooth engagement regions. The at least one breach region is configured to breach or bend when a pulling force is applied to one or both of the tooth engagement regions such that one or both of the attachment regions are detached from respective attachments.
