Abstract: Embodiments relate to techniques for real-time and post-scan visualization of intraoral scan data, which may include 3D images, 3D scans, 3D surfaces and/or 3D models. In one embodiment, an intraoral scanning system comprises a plurality of image sensors to periodically generate a set of intraoral two-dimensional (2D) images, wherein for each set of intraoral 2D images each image sensor of the plurality of image sensors is to generate an intraoral 2D image, and wherein relative positions and orientations of the plurality of image sensors are known. The intraoral scanning system further comprises a computing device, wherein the computing device is to perform the following for each set of intraoral 2D images: generate a combined intraoral image based on merging the set of intraoral 2D images together during scanning; and output the combined intraoral image to a display.

Abstract: Systems and methods for improved visual prosthetic and orthodontic treatment planning are provided herein. In some aspects, a method for preparing a tooth of a patient is disclosed. The method may comprise building a model of a dentition of the patient including a model of the initial shape of tooth. The method may also include determining a final prepared shape of the tooth. In some aspects, the method may also include generating a treatment plan comprising a plurality of steps to modify the initial shape of the tooth to the final prepared shape of the tooth. The method may also include rendering visualizations for the plurality of steps of the treatment plan. The visualizations may depict the removal of tooth material to modify the initial shape of the tooth to the final prepared shape of the tooth.

Abstract: Orthodontic appliances and associated methods are provided. In some embodiments, an orthodontic appliance includes an appliance shell configured to reposition a patient's teeth from a first arrangement toward a second arrangement. The appliance shell can include a plurality of shell segments, each shell segment including a first material having a first elastic modulus. The appliance shell can also include a plurality of elastic segments, each elastic segment including a second material having a second elastic modulus less than the first elastic modulus. Each elastic segment can be coupled to a respective adjacent pair of shell segments.

Abstract: In a method of generating a virtual 3D model of a dental site, scan data comprising an intraoral image is received during an intraoral scan of a dental site. A representation of a foreign object is identified in the intraoral image based on a color analysis of the scan data. The intraoral image is modified by removing the representation of the foreign object from the intraoral image. Additional scan data comprising a plurality of additional intraoral images of the dental site is received during the intraoral scan. A 3D surface of the dental site is then generated using the modified intraoral image and the plurality of additional intraoral images.

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 identifies one or more 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 the orthodontic treatment plan based on a result of the comparing. The processing device additionally determines one or more corrective actions for the orthodontic treatment.

Abstract: A system for intraoral scanning comprises a scanner to generate image data of a dental site and a computing device. The computing device receives the image data of the dental site, the image data comprising a representation of the dental site and a representation of a reference object at the dental site. The computing device selects library data for the reference object from library data for a plurality of reference objects in a library. The computing device aligns the library data for the reference object with the image data.

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.
