Abstract: A mold is for thermoforming a dental appliance. The mold includes a first section of the mold and a second section of the mold. The second section includes a feature having a complex shape, an undercut, or a bite edge. The mold further includes 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 and the second section to be removed from the dental appliance after the dental appliance is formed over the mold. The first threshold force is less than a second threshold force that would damage or permanently deform the dental appliance.

Abstract: An intraoral scanner comprises a housing, a light source for generating light, an optics system for focusing the light, a detector for detecting returning light reflected off an intraoral object, and a focus shifting mechanism configured to shift a focal plane of the optics system. The optics system is configured such that, after having passed through the optics system, an outermost chief ray of the light with respect to an optical axis of the optics system is divergent to the optical axis and an outermost marginal ray of the light with respect to the optical axis is parallel or divergent to the optical axis.

Abstract: Methods and systems for taking images of a patient's teeth for tracking a progress of an orthodontic procedure. The methods and systems include a mobile device holder with one or more adjustable stops for providing a compressive force on a mobile device placed therein; a cheek retractor coupled to the mobile device holder; and a user interface on the mobile device indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.

Abstract: A method includes generating a blurred color representation of an estimated post-treatment arrangement of teeth of an individual to be used for generation of a simulated color image of a post-treatment smile of the individual based on first depth information of a color image of a pre-treatment smile, color information of the color image of the pre-treatment smile, and a simulated colorless image of the estimated post-treatment arrangement of the teeth that comprises second depth information. The method further includes generating the simulated color image of the post-treatment smile of the individual based on the blurred color representation of the estimated post-treatment arrangement of the teeth and the simulated colorless image of the estimated post-treatment arrangement of the teeth.

Abstract: A system for curing flowable dental material may include an intraoral scanner configured to capture 3D data, a dental-material-curing light source configured to emit curing light from the probe, a processor, and memory. The memory may include instructions that when executed by the processor cause the system to receive a 3D model of the dentition of the patient from a dental treatment plan, receive scan data of the dentition of the patient, and determine, while receiving the scan data, an area of illumination by the dental-material-curing light source with respect to a dentition of a patient, based on the received scan data.

Abstract: Methods and systems for building a 3D model of teeth from a 2D image are provided, including: accessing a first 2D image depicting a patient's face and teeth; determining edges of one or more oral features in the first 2D image; obtaining an arch model including teeth with generic parameters; determining one or more case-specific parameters for a shape of at least one of the patient's teeth by fitting the teeth of the arch model to the edges of the one or more oral features in the first 2D image; generating a 3D parametric model of the patient's teeth by adjusting at least one of the teeth of the arch model based on the one or more case-specific parameters; and outputting the 3D parametric model or a second 2D image based on the 3D parametric model for display to a user on a display device.

Abstract: In embodiments, a system for scanning an intraoral cavity comprises an intraoral scanner to generate intraoral scan data of the intraoral cavity and viewfinder images of the intraoral cavity, a display, and a processing unit operatively connected to the intraoral scanner and to the display. The processing unit is to: receive the intraoral scan data and the viewfinder images from the intraoral scanner; generate a three-dimensional (3D) digital model of the intraoral cavity using the intraoral scan data; output the 3D digital model to the display; output the viewfinder images to the display; determine which portions of the intraoral cavity have been scanned; determine a current field of view of the intraoral scanner; determine a visual indicator that provides guidance for positioning and orienting the field of view of the intraoral scanner; and output the visual indicator to the display.

Abstract: Methods and apparatuses for orthodontic treatment planning. A treatment plan may be for a patient's teeth and for a specific dental professional. A set of combined treatment preferences may include a first set of rules converted from a set of textual instructions from the specified dental professional into a domain-specific language specific to the specified dental professional. The textual instructions may include unscripted instructions. A second set of rules may be converted from a set of scripted instructions from the specified dental professional. The scripted instructions may include responses from a script of predefined choices. An orthodontic treatment plan may be generated for the patient's teeth using the set of combined treatment preferences and a digital model of the patient's teeth.
