Abstract: Methods, devices, and systems for placing dental auxiliaries on teeth and/or removing dental auxiliaries from teeth are provided. In some embodiments, a device for removing a dental auxiliary from a tooth includes: a first elongate member having a proximal end and a distal end; a second elongate member having a proximal end and a distal end, where the first and second elongate members are pivotally coupled to each other; a scraper at the distal end of the second elongate member, where the scraper is configured to apply force to the dental auxiliary to remove the dental auxiliary from the tooth; and a pair of sidewalls configured to capture debris resulting from the removal of the dental auxiliary from the tooth.

Abstract: Devices, methods, and systems for placing dental auxiliaries on teeth are provided. In some embodiments, for example, a dental auxiliary positioner for placing a dental auxiliary on a tooth includes: a registration element configured to receive a patient's tooth; and an auxiliary support coupled to the registration element and further coupled to an auxiliary, where the auxiliary support is configured to position the auxiliary against a surface of the tooth, and where the auxiliary support includes a frame extending at least partially around the auxiliary, one or more struts coupling the auxiliary to the frame, and a flexible bridge coupling the frame to the registration element, where the flexible bridge is configured to bend in one or more directions relative to the tooth to adjust the position of the auxiliary on the surface of the tooth.

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.

Abstract: Systems and methods for designing additively manufactured objects are provided. In some embodiments, a method includes receiving a treatment plan for a patient's teeth, and determining a set of appliance parameters for a dental appliance configured to implement the treatment plan. The method can also include determining a set of manufacturing parameters for a fabrication system to be used to additively manufacture the dental appliance. The method can further include generating a 3D digital representation of an appliance geometry for the dental appliance. The appliance geometry can be configured to mitigate loss of fidelity at a target region of the dental appliance due to at least one manufacturing parameter of the fabrication system.
