  • Patent number: 11872102
    Abstract: A processing device receives image data of an actual condition of a patient's dental arch at a stage of an orthodontic treatment plan. The processing device compares the image data of the actual condition of the patient's dental arch to a planned condition of the patient's dental arch for the stage of the orthodontic treatment plan. The processing device determines an updated orthodontic treatment plan based on one or more differences between the actual condition of the patient's dental arch and the planned condition of the patient's dental arch determined from the comparing. The processing device generates one or more three-dimensional (3D) models for one or more new orthodontic aligners in accordance with the updated orthodontic treatment plan.

  • Publication number: 20230368479
    Abstract: A mobile device comprises a display, an image capture device that generates image data of a face of a viewer of the display, and a processing device. The processing device receives the image data and sends the image data to a computing device. The computing device 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; and sends the updated image data to the mobile device. The mobile device outputs the updated image data to the 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 display rather than a true depiction of the dental arch.

  • Patent number: 11426053
    Abstract: Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.

  • Patent number: 11382720
    Abstract: Embodiments are directed to techniques, methods and systems for analyzing orthodontic treatments during treatment and correcting the orthodontic treatments when analysis shows that a patient's actual dentition for a stage of treatment deviates from a planned dentition for the stage of treatment. Analysis may be performed by comparing image data of an actual condition of the patient's dental arch at a stage of treatment to a planned condition of the patients dental arch for the stage of treatment, and identifying clinical signs that the actual condition of the patient's dental arch has a deviation from the planned condition of the patient's dental arch for the stage of orthodontic treatment.

  • Patent number: 10733805
    Abstract: In an embodiment, a processing device receives image data of a face from an image capture device associated with an augmented reality (AR) display. The processing device processes the image data to a) identify a mouth in the image data, b) identify a dental arch in the mouth, and c) determine a position of the dental arch relative to a position of the AR display. The processing device determines a treatment outcome for the dental arch, generates a visual overlay comprising an indication of the treatment outcome at the determined position of the dental arch, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display.
