Abstract: A method of generating a 3D model includes: determining a 3D surface comprising a preparation tooth using a first plurality of intraoral scans generated by an intraoral scanner at a first time; receiving one or more additional intraoral scans of the preparation tooth that were generated by the intraoral scanner at a second time; determining a change to one or more portions of the preparation tooth between the three-dimensional surface and the one or more additional intraoral scans; determining, based at least in part on the change to the preparation tooth, whether to use a) the 3D surface, b) data from the one or more additional intraoral scans or c) a combination of the 3D surface and the data from the one or more additional intraoral scans to depict one or more portions of the preparation tooth; and generating the 3D model comprising the preparation tooth.

Abstract: A method for preparing a tooth crown may include generating a 3D model of an external surface of a patient's tooth and generating a 3D model of an external surface of a first crown based on the 3D model of the external surface of the patient's tooth. The method may also include preparing the patient's tooth to receive the first crown while generating the 3D model of the external surface. A 3D model of the prepared tooth my be generated. A 3D model of an internal surface of the first crown may also be generated. The 3D model of the external surface and the 3D model of the internal surface may form a 3D model of the first crown.

Abstract: Systems and methods of simulating dental treatments are disclosed. A method may include capturing a first 2D image of a patient's face, including the patient's teeth, building a parametric 3D model of the patient's teeth and gingiva based on the first 2D image, developing a simulated outcome of a dental treatment of the patient's teeth by rendering the parametric 3D model with the patient's teeth in one or more positions and/or orientations corresponding to the treatment goals of the dental treatment plan, and rendering a second 2D image of the patient's face with gingiva and teeth according to a simulated outcome of the dental treatment plan. As noted herein, the dental treatment plan may include orthodontic and/or restorative elements. The simulated outcome may correspond to estimated outcomes and/or intended outcomes of the dental treatment plan.

Abstract: A system for accounting for changes in surface topology may include an intraoral scanner and a computer system comprising instructions that, when executed, causes the computer system to: receive initial scan data of a first surface portion of tissue and a second surface portion of tissue, the scan data of the first surface portion of tissue having a first surface topology, generate a demarcation between the first surface portion and the second surface portion, receive rescan data of an intraoral cavity of the patient that includes surface data of the first surface portion of tissue having a second surface topology, update the data of the first surface portion of tissue by modifying only at least a portion of the data according to the demarcation using at least a portion of the rescan data, and output a 3D model of the patient's teeth based on the updated data.

Abstract: Calibrating an intraoral scanner includes obtaining reference data of a reference three-dimensional (3D) representation of a calibration object and obtaining, based on the intraoral scanner being used by a user to scan the 3D calibration object, and from one or more device to real-world coordinate transformations of two-dimensional (2D) images of the 3D calibration object, measurement data. Calibrating the intraoral scanner further includes aligning the measurement data to the reference data to obtain alignment data and updating, based on the alignment data, said one or more transformations.

Abstract: Pressure sensor modules adapted for use with a dental appliance may include one or more pressure sensors encapsulated within a sealed cavity in which one or more walls of the sealed cavity are deformable so as to transduce pressure from outside of the cavity, due to deformation or movement of the dental appliance and/or the environment around the dental appliance, including the environment within a patient's mouth when wearing the dental appliance. Also described herein are method of making and using these apparatuses to identify and/or monitor the dental appliance, a patient condition and/or an orthodontic treatment. Also described herein are methods and apparatuses for identifying and/or characterizing sleep apnea using these pressure sensor modules.

Abstract: Methods and apparatuses for applying to elicit desired tooth movement, e.g., to align teeth, including one or more attachments that each include a base region that may rigidly attach to a tooth, a top region that may couple with an orthodontic appliance, and one or more elastically deformable biases that allows the top region to move relative to the base region force is applied to the top region. The attachment may apply a restoring force to move one or more teeth when the top region is deformed.
