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: System and methods for positioning 3D virtual brackets on teeth for the precise positioning of conventional brackets and wire. Various reference features may be calculated for the teeth and used to calculate a position for the virtual bracket. Reference features that are calculated include curve of Spee, Andrew's plane, and a facial axis of the clinical crown for the teeth.

Abstract: An intraoral scanner generates 2D images of a dental site and 3D intraoral scans of the dental site. The computing device receives the 2D images of the dental site and the 3D intraoral scans of the dental site from the intraoral scanner, generates a 3D model of the dental site based on the 3D intraoral scans of the dental site, and processes at least one of a) one or more of the 2D images of the dental site, b) one or more of the 3D intraoral scans of the dental site, or c) data from the 3D model of the dental site to identify one or more intraoral areas of interest (AOIs) at the dental site. The computing device determines a dental condition associated with the one or more intraoral AOIs, and determines a manner for scanning the one or more intraoral AOIs.

Abstract: An intraoral scanning system includes an intraoral scanner and a computing device. The computing device receive a plurality of intraoral scans from the intraoral scanner during an intraoral scanning session; registers the plurality of intraoral scans together based on overlapping features of the plurality of intraoral scans; generates a first three-dimensional (3D) surface based on the plurality of intraoral scans; receives one or more additional intraoral scans; determines that the one or more additional intraoral scans fail to satisfy one or more registration criteria for registering to at least one of the plurality of intraoral scans or the first 3D surface; and generates a second 3D surface based on the one or more additional intraoral scans.

Abstract: Embodiments relate to an aligner breakage solution that tests probability of aligner breakage at weak points. A method includes gathering a digital model representing an aligner for a dental arch of a patient, receiving material property information for a material to be used to manufacture the aligner, and analyzing one or more regions of the aligner. Analyzing a region of the aligner comprises simulating application of a load around the region, determining at least one of a stress, a strain or a strain energy density at the region, evaluating a strength of the aligner at the region, and determining whether the region satisfies a damage criterion based on the strength of the aligner at the region.

Abstract: Systems and methods for rapidly and reliably determining an arch with of a patient's dental arch. A patient's dentition may be scanned and/or segmented. Arch width may be determined between points of intersection on the occlusal surface and a long axis of each tooth between one or more of: canine, first bicuspid, first primary molar, second bicuspid, second primary molar, and permanent first molar. Arch widths of different modified versions of the patient's dentition may be dynamically compared the patient's starting dentition, or to each other, and may be dynamically updated as the user modifies or switches between one or more 3D models of the patient's dentition.
