Abstract: Methods and systems for imaging removable dental appliances. Image data taken while a removable dental appliance was worn on a patient's teeth may be used to identify one or more locations of undesirable contact between the removable dental appliance and the patient's teeth and/or one or more attachments on the patient's teeth. The one or more locations of undesirable contact can correlate with undesirable tooth movement compared to expected tooth movement according to a treatment plan. A three-dimensional (3D) model of the removable dental appliance and the patient's teeth may be displayed on a user interface, with the identified one or more locations of undesirable contact highlighted in the 3D model. An alert of the identified one or more locations of undesirable contact may be emitted via the user interface.

Abstract: Aligner systems and methods including a sequence of aligners having energy-delivering elements. For example, first and second aligners of the sequence of aligners may include first and second polymer shells that have shapes for applying respective first and second local forces to first and second regions of a dental arch to move one or more first teeth and one or more second teeth, respectively. The first and second aligners may also include corresponding first and second heating elements that are arranged to heat first and second target regions of the dental arch associated with moving the one or more first teeth and one or more second teeth, respectively. Heat energy from the first and second heating elements may improve an outcome of respective first and second stages of a treatment plan.

Abstract: Aligner attachment placement devices including a frame configured to extend over at least a portion of a dental arch, an attachment support extending from a first side of the frame, an aligner attachment frangibly connected to the attachment support, a first and second registration anchor, and a retention support extending from a second side of the frame. In some cases, a gap portion of the frame between the first and second registration anchors may be configured to suspend over one or more teeth of the dental arch. The retention support may be separate from and located between the first and second registration anchors. The retention support may include an extension arm and a tooth contact portion, where at least part of the extension arm has a smaller width than the tooth contact portion.

Abstract: Described herein are intraoral appliances with adaptive cellular materials and structures to provide enhanced mechanical properties and orthodontic functionality, and related methods. The described appliances may have higher Young's modulus and elongation rate than appliances made from conventional materials. Further, the described appliances may have desirable non-linear force/strain profiles. Additionally, the control provided by using cellular structures allow for increased customization for individual patients. Thus, the described appliances may be more effective, have longer appliance lifetimes and/or provide less discomfort to patients.
