Abstract: Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some aspects, a method for fabricating an orthodontic appliance for treating a patient's teeth is disclosed. The method may comprise determining a movement path to move a tooth from an initial arrangement towards a target arrangement; determining a force system to move the tooth along the movement path; determining a variable gable bend to produce the force system; determining a geometry for a tooth receiving cavity of the appliance based on the variable gable bend; and generating instructions for fabricating the appliance having a tooth receiving cavity formed according to the geometry for the tooth receiving cavity.

Abstract: Strategies that reduce shrinkage and ultimately warping of parts that are directly fabricated from photopolymer resins. This increases the accuracy of directly fabricated parts, which is essential for patient specific applications. Implementing these strategies can reduce the need for directly fabricated parts to have supporting structures, which can reduce pre-processing and post-processing steps and facilitate an easier route for production level scale of additive manufacturing.

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: Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some embodiments, a method includes determining an appliance geometry for a dental appliance. The appliance geometry can include a first region representing a shell comprising a plurality of teeth receiving cavities, and a second region representing at least one integrally formed component to be integrally joined to the shell. The method can also include generating instructions including a first digital representation of the shell based on the first region, and a second digital representation of the at least one integrally formed component based on the second region. The method can further include transmitting the instructions to a fabrication system configured to additively manufacture the dental appliance by fabricating the shell based on the first digital representation, concurrently with fabricating the at least one integrally formed component based on the second digital representation.

Abstract: A mold includes a first section, a second section, and a weakened region that joins the first section to the second section. The weakened region is breakable, deflectable, or deformable in response to a first threshold force to enable the first section to be removed from a shell independently of the second section after the shell is formed over the mold. The first threshold force is less than a second threshold force that would damage or permanently deform the shell. The first section is a first mold of at least a portion of one or more first teeth of a dental arch and the second section is a second mold of at least a portion of one or more second teeth of the dental arch.
