Abstract: Embodiments include computing device readable mediums, computing devices, and methods for synchronized viewing of file manipulations. One method embodiment includes creating a synchronized session between computing devices. The method further includes distributing copies of a file from one computing device to another and allowing each computing device to locally manipulate the file. According to the method, manipulating the file on a first computing device initiates a data stream including executable instructions for manipulating the file on a second computing device. The method also includes forwarding the data stream to the second computing device and manipulating the file according to the data stream received. The method further includes restricting manipulation functionality on the second computing device to the file based on the forwarded data stream, where the restriction of the manipulation functionality does not interrupt functionality of each computing device outside the file.
Abstract: A digital data set representing a pre-scanned tooth geometry, including generic crown data, is merged with data representing a scanned patient tooth crown image, which lacks sufficient data to completely represent a complete tooth crown.
Abstract: The present disclosure includes method, system, apparatus, and indicator embodiments. For example, one system for monitoring orthodontic treatment includes an appliance for placement over one or more teeth and multiple wear indicators including at least a first wear indicator having a first wear rate and a second wear indicator that has a second wear rate that is different from the first.

Abstract: Systems and methods are disclosed for producing a digital model by providing a digital model of a tooth; providing a digital model of at least one attachment device having two or more portions, the digital model of the attachment device having the two or more portions extending through two or more surfaces of the tooth; and positioning the digital model of the attachment device on the digital model of the tooth to produce a combined computerized model.
Abstract: System and method for automatic construction of orthodontic reference objects, such as the occlusal plane, arch form, and the local occlusal plane for a patient's teeth are disclosed. In accordance with an exemplary embodiment, a computer-implemented system and method for automatic construction of orthodontic reference objects comprises receiving three dimensional data for the teeth, setting an initial direction for a normal of the occlusal plane, determining tips for selected teeth, calculating a plane that matches the determined tip, and determining a new normal for the calculated plane.
Abstract: A system and method for modeling of complete tooth, including root and crown, of a patient to facilitate orthodontic treatment are provided, wherein a generic tooth modeling is combined with a tooth crown modeling for a patient to yield a complete tooth modeling. A generic tooth three-dimensional model for a particular tooth is morphed with a three-dimensional model of a patient's crown for the corresponding tooth to yield a complete three-dimensional model for that tooth. Modeling techniques can be conducted with computer-based systems, such as systems configured for storing patient data and generic tooth data, morphing such data and/or facilitating additional orthodontic treatment applications, through the use of one or more algorithms. Adjustment of the complete tooth model for the tooth can be provided through additional patient information, such as X-ray imaging, to address variations in root shape between a generic root and an actual root shape for a patient.
Abstract: An apparatus and method define a fit a set of upper and lower teeth in a masticatory system of a patient by generating a computer representation of the masticatory system of the patient; and determining an occlusion from the computer representation of the masticatory system using one or more keys.

Abstract: Fabricating polymeric shell appliances for moving a patient's teeth. A first tooth arrangement model is formed by placing models of individual teeth representing the patient's teeth onto a plurality of platforms of a frame approximating a shape and size of a jaw of the patient, wherein each model tooth comprises a coupling member for coupling the model tooth with a platform of the plurality of platforms. A first polymeric shell appliance is formed over the first tooth arrangement model or a copy thereof. At least a second tooth arrangement model is formed by rearranging at least some of the individual teeth relative to the frame. At least a second polymeric shell appliance is formed over the second tooth arrangement model or a copy thereof.
Abstract: A method for manufacturing wrinkled dental aligner for a patient's tooth includes developing a digital dental aligner model specifying at least one wrinkled surface on a dental aligner and producing a dental aligner having the wrinkled surface in accordance with digital dental aligner model.
Abstract: An apparatus for monitoring orthodontic treatment compliance includes an appliance adapted to be worn over one or more teeth; and a compliance indicator mounted on the appliance to indicate compliance.

Abstract: A system for organizing dental aligners for a subject includes a plurality of dental aligners configured to move the subject's teeth at different steps of an orthodontic treatment and one or more connectors (including frangible connectors) configured to connect a plurality of dental aligners in an order that is consistent with the sequence in which the dental aligners are to be used by the subject in the orthodontic treatment.
Abstract: A system for repositioning teeth comprises a plurality of individual appliances that are treated with a lubricious composition. The appliances are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The system of appliances is usually configured at the outset of treatment so that the patient may progress through treatment without the need to have the treating professional perform each successive step in the procedure.
