    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: A dental attachment placement device comprises a plurality of articulated registration elements shaped for placement on a plurality of teeth, which can facilitate placement, accommodate tooth movement, and improve alignment of the registration elements with the teeth, so as to accurately position an attachment for placement. The plurality of registration elements may comprise one or more attachment supports and one or more retention supports extending from the plurality of registration elements. A dental attachment can be removably coupled to the attachment support. The plurality of registration elements and attachment supports may be located on opposing sides of one or more teeth in order to maintain placement prior to adhering the attachment to the tooth. In some embodiments, each of the plurality of registration elements comprises a tooth registration surface shaped to engage the tooth with a specific position and orientation for accurate positioning of the attachment.
