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: Systems and methods for additive manufacturing are provided. In some embodiments, a method for additive manufacturing includes forming a portion of an additively manufactured object within a reservoir of curable material by scanning a plurality of energy beams of a plurality of energy sources through a plurality of respective scanning regions in the curable material. The scanning regions can overlap at one or more object locations, such that a combined energy dosage delivered to the one or more object locations by two or more of the energy beams is greater than or equal to a threshold dosage for solidifying the curable material. The method can further include advancing the reservoir of curable material relative to the energy sources. The forming and advancing processes can be repeated to fabricate the additively manufactured object.
