Abstract: Embodiments include receiving intraoral scan data comprising a plurality of intraoral images of a dental site generated during scanning of the dental site by an intraoral scanner, a plurality of ink markings each comprising a pattern of ink having been temporarily stamped or tattooed onto a gingival surface at the dental site prior to the scanning of the dental site, wherein at least two intraoral images of the plurality of intraoral images comprise representations of one or more ink markings of the plurality of ink markings. Embodiments further include performing registration between the plurality of intraoral images based at least in part on the one or more ink markings, generating a three-dimensional (3D) model of the dental site using the plurality of intraoral images that have undergone registration, and outputting the generated 3D model to a display.

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.

Abstract: The present disclosure includes methods, systems, and devices for prioritization of three dimensional dental elements. One method for prioritizing three dimensional dental elements includes receiving a virtual initial dental data set (IDDS) of teeth having spatial information regarding the positions of a number of teeth in the virtual IDDS with respect to each other for presentation of the teeth in a virtual three dimensional space to be viewed on a user interface, setting prioritization values of a number of elements of one or more of the number of teeth, and prioritizing the number of elements to be selected by a user based upon their prioritization values.

Abstract: Laser cutting systems and methods are described herein. One or more systems include a laser, an optical component, a fixture for holding a support with a part positioned on the support, and a controller. The controller is configured to identify a cut path for trimming excess material from a dental appliance, determine adjustment instructions for adjusting a focal length of the laser to cut along the cut path, and trim the excess material from the dental appliance along the cut path with the laser. The focal length is adjusted by adjusting at least one of: the laser, the optical component, and the fixture, and while moving the fixture at a constant speed relative to the laser to avoid increasing a brittleness of a polymer material of the dental appliance along the cut path.

Abstract: A scan model that is a mathematical model to simulate an imaging process performed by an x-ray imaging device that created a two-dimensional x-ray image of at least one tooth is generated. The scan model uses an initial estimate of one or more parameters of the x-ray imaging device. The one or more parameters include a scan angle parameter indicative of a scan angle of the x-ray imaging device. A two-dimensional contour of a three-dimensional model is adjusted to cause a first component of the two-dimensional contour to approximately align with a second component of the two-dimensional x-ray image. The scan model is calibrated based on data obtained from adjusting the two-dimensional contour.
