    Abstract: Aligner attachment placement devices for placing one or more aligner attachments on teeth. The placement devices can include registration anchors, retention supports, an aligner attachment, and an attachment frame that at least partially surrounds a perimeter of the aligner attachment. The registration anchors can have occlusal contact surfaces that are shaped to register with occlusal surfaces of one or more teeth. The retention supports can have lingual contact surfaces that are shaped to register with lingual surfaces of one or more teeth. The aligner attachments can be shaped to interact with one or more aligners to impart forces on one or more of the teeth. The placement device can include multiple aligner attachments. The attachment frame can include one or more struts that frangibly connect the aligner attachment(s) to the attachment frame.

    Abstract: A removable arch adjustment appliance includes a removable shell having a plurality of cavities formed therein, wherein the plurality of cavities are shaped to receive at least one posterior tooth of a patient on each side of a patient's jaw. The shell can include an elastic transpalatal element that spans a palate of the patient and provides force to expand at least one of the spaces between the posterior teeth on each side of a patient's jaw or the palate of the patient. The transpalatal element can include a predetermined force characteristic, a number of force control elements to control the force provided by the transpalatal element, and/or a regulating structure to balance and direct the force provided by the transpalatal element, wherein the transpalatal element has a width specific to a stage of a treatment plan.
