Abstract: An intraoral scanner comprises a light source, a moveable opto-mechanical module, an axial actuator, and an image sensor. The light source is configured to generate light that is to be output onto an object external to the intraoral scanner. The moveable opto-mechanical module comprises integrated projection/imaging optics and an exit pupil, the projection/imaging optics having an optical axis, wherein the projection/imaging optics are entirely integrated into the moveable opto-mechanical module. The axial actuator is coupled to the projection/imaging optics and configured to move the moveable opto-mechanical module comprising an entirety of the projection/imaging optics in the optical axis to achieve a plurality of focus settings. The image sensor is configured to receive reflected light that has been reflected off of the object external to the intraoral scanner for the plurality of focus settings.

Abstract: A mobile computing device comprises an AR display, an image capture device that generates image data of a face of a viewer of the AR display, and a processing device. The processing device receives the image data; processes the image data to identify a position of a dental arch in the image data; determines a treatment outcome for the dental arch; generates a post-treatment image of the dental arch that shows the treatment outcome; generates updated image data comprising a superimposition of the post-treatment image of the dental arch over the received image data depicting the face of the viewer; and outputs the updated image data to the AR display, wherein the post-treatment image of the dental arch is superimposed over the dental arch in the received image data such that the post-treatment image is visible in the AR display rather than a true depiction of the dental arch.

Abstract: An orthodontic aligner includes a first plastic segment having a first shape that fits over a first portion of a dental arch of a patient, a second plastic segment having a second shape that fits over a second portion of the dental arch of the patient, and a connector that joins the first plastic segment to the second plastic segment. The connector is configured to be disposed along a lingual side of one or more additional teeth of the patient without exerting a clinically significant force on the one or more additional teeth. The connector spans a gap between the first plastic segment and the second plastic segment, the gap corresponding to the one or more additional teeth that are not to receive the clinically significant force. The connector includes a flexible material that will perform at least one of flex, move or change shape responsive to applied forces.

Abstract: Apparatuses (e.g., systems and devices, including dental appliances and series of dental appliances) that may include one or more conversion appliances that may be worn on a subject’s during a treatment plan without applying substantial orthodontic forces on the subject’s teeth. The conversion appliances described herein may be configured to provide the user with a similar feel as a dental appliance. In some cases these appliances are not part of the dental treatment plan but are added between one or more stages. The dental professional may include one or more conversion appliances between one or more stages of a dental treatment plan, and conversion appliances may be added after the dental treatment plan has been finalized.

Abstract: Systems, methods, and devices for producing appliances for expansion of the arch of a patient are provided. An arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The retention portion comprises a flexible portion and a stiff portion. The force generating portion applies a force to move teeth associated with the flexible portion, while the stiff portion resists movement of its associated teeth. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.

Abstract: The present disclosure provides computing device implemented methods, computing device readable medium, and molds for filling undercut areas of teeth relative to an axis of placement. Filling undercut areas of teeth relative to an axis of placement can include calculating an undercut area of a tooth relative to an axis of placement of part of a dental appliance over a number of teeth and a height of contour that is defined based on the axis of placement. Filling undercut areas of teeth relative to an axis of placement can also include filling in a part of the undercut area of the tooth with a virtual filler wherein the undercut is filled to within a threshold distance from the tooth that is defined relative to the axis of placement and the height of contour.
