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: Intraoral scanning systems for displaying 3D models of a patient's dental arch and near-IR images from the dental arch. These systems may include a wand with one or more image sensors and processors for processing the 3D models and near-IR information. The 3D models may include surface (e.g., color) information and the near-IR images may include information on internal structures, including enamel and dentin.

Abstract: An intraoral scanning system for scanning an intraoral dental structure of a patient in a dental procedure may include an intraoral scanner and one or more processors coupled to the intraoral scanner and programmed with instructions that when executed by the one or more processors cause the intraoral scanning system to build a 3D model of the intraoral dental structure of the patient based on scan data acquired via the intraoral scanner and output feedback on a display. The feedback may include highlighting a portion of the 3D model that includes scan data that includes a finish line of the intraoral dental structure, wherein the scan indicates that the finish line is not suitable for receiving a prosthetic.

Abstract: A processor receives first intraoral scan data comprising a first depiction of a dental site; generates a virtual three-dimensional (3D) model of the dental site using the first intraoral scan data; and processes at least one of the first intraoral scan data or data from the virtual 3D model to identify an unclear feature. The processor outputs instructions to generate second intraoral scan data of the dental site depicting the portion of the dental site that is unclear; receives the second intraoral scan data; and updates the virtual 3D model of the dental site using the second intraoral scan data, wherein the portion of the dental site that was unclear in the virtual 3D model is replaced with information from the second intraoral scan data.

Abstract: A method of fabricating a dental appliance includes receiving a digital three-dimensional model of a mold for a dental arch of a patient, the digital three-dimensional model of the mold comprising one or more features associated with a cut line. The method further includes fabricating the mold by a rapid prototyping machine using the digital three-dimensional model, the mold having the one or more features. The method further includes thermoforming the dental appliance over the mold, wherein the one or more features cause the dental appliance to have one or more markings or elements for the cut line. The method further includes removing the dental appliance from the mold, and trimming the dental appliance along the cut line using the one or more markings or elements.

Abstract: Orthodontic appliances and systems are provided. In some embodiments, an orthodontic appliance for repositioning a patient's teeth includes a first shell section shaped to receive a first portion of the patient's teeth and a first discontinuity formed on the first shell section, and a second shell section shaped to receive a second portion of the patient's teeth and a second discontinuity formed on the second shell section. The orthodontic appliance can also include a first elastic member coupled to the first shell section, such that the first elastic member interacts with the first discontinuity to exert a first force on the first portion of the patient's teeth. The orthodontic appliance can also include a second elastic member coupled to the second shell section, such that the second elastic member interacts with the second discontinuity to exert a second force on the second portion of the patient's teeth.

Abstract: Releasable and removable palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These releasable palatal expanders are adapted for ease in removal by the patient or caregiver, and may include a breach region configured to predictably bend or break when a pulling force is applied. The palatal expander apparatuses described herein may include one or more locks for locking the palatal expander onto the patient's teeth. The lock(s) may be unlocked to release the palatal expander from the teeth. A lock may include a control for manually unlocking the lock. Unlocking the locks may allow the palatal expander to automatically disengage from the patient's teeth.

Abstract: An image of a dental arch comprising a preparation tooth is generated by an image capture device associated with an augmented reality (AR) display. The image of the dental arch is registered to previous image data associated with the dental arch. A visual overlay associated with a dental prosthetic to be placed on the preparation tooth is generated based on the registering of the image of the dental arch to the previous image data associated with the dental arch. The visual overlay is output to the AR display, wherein the visual overlay is superimposed over a view of the preparation tooth on the AR display.
