Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a method includes receiving a plurality of additively manufactured objects having excess material thereon. The method can include removing the excess material from the plurality of additively manufactured objects by rotating the plurality of additively manufactured objects. The method can also include adjusting an environmental temperature while rotating the plurality of additively manufactured objects according to a dynamic temperature profile that facilitates removal of the excess material from the plurality of additively manufactured objects. The dynamic temperature profile can include (a) a first temperature configured to decrease a viscosity of the excess material, and (b) a second temperature configured to increase a stiffness of the plurality of additively manufactured objects.

Abstract: Systems, methods, and devices for post-processing additively manufactured objects are disclosed herein. In some embodiments, a system includes a plurality of containers configured to receive a plurality of additively manufactured object having excess material thereon. The system can include a rotor having a central shaft and a plurality of arms, each arm having a first end and a second end opposite the first end. The first end of each arm can be coupled to the central shaft and a second end of each arm can be coupled to a respective container of the plurality of containers.

The first appliance can be configured to receive at least one tooth of a first jaw and have a first number of bite adjustment structures extending from the lingual surface of the first appliance. The first number of bite adjustment structures can have a first shape and location specific to a first stage of the treatment plan. The second appliance can be configured to receive at least one tooth of the second jaw, have a second number of bite adjustment structures extending from the second appliance and be designed to make contact with the first number of bite adjustment structures.

Abstract: Provided herein are systems and methods for scoring a post-treatment tooth position of a patient's teeth. A patient's dentition may be scanned and/or segmented. Raw dental features, principal component analysis (PCA) features, and/or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A classifier can identify and/or output the post-treatment tooth position of the patient's teeth.

Abstract: A system for generating missing data for 3D models of intraoral structures of a patient. The system may include a hand-held intraoral scanner and a computer having instructions that the system to scan the intraoral structure of a patient to generate first 3D data of the surface of a prepared tooth, generate a 3D virtual model of the prepared tooth based on the first 3D data, determine the 3D virtual model is missing a surface associated with the prepared, generate second 3D data approximating the surface that is determined to be missing from the 3D virtual model intraoral structure that is missing, and combine the second 3D data with the 3D virtual model such that the 3D virtual model includes the approximated surface, wherein the approximated surface approximates the prepared tooth associated with the surface determined to be missing from the 3D virtual model.

Abstract: A method and system for thermal forming an object. A mold is provided, a shape of which corresponds to a desired shape of the object. A material is inserted into a heating area, and the material is heated using a plurality of independently controllable heat sources that heat different areas of the material. The heated material is then disposed over or into at least a portion of the mold so as to deform the material. The deformed material may then be trimmed so as to form the object.

Abstract: A system includes a partial enclosure configured to hold resin. The system further includes one or more structures configured to at least partially cover the resin. The one or more structures are configured to prevent evaporation of the resin. The system further includes a build platform configured to support an object that is being formed from layers of the resin. A first blade is configured to provide the layers of the resin to form the object on the build platform.

Abstract: A method includes obtaining image(s) of a dental device, determining file(s) including at least one of a first model of the dental device or a second model of a mold, determining an intended property for the dental device based on at least one of the first model or the second model, and determining an actual property of the dental device from the image(s). The method further includes determining whether a cutline variation, an arch variation, and/or a bend of the dental device is detected between the dental device and the first model and/or the second model by comparing the intended property with the actual property. The method further includes determining whether there is a possible defect in the dental device based on whether the cutline variation exceeds a cutline variation threshold, the arch variation exceeds an arch variation threshold, and/or the bend exceeds a bend threshold.

Abstract: The present invention provides methods and systems including orthodontic tooth positioning appliances. An exemplary appliance can include teeth receiving cavities shaped such that, when worn by a patient, repositioning the patient's teeth from a first arrangement toward a subsequent or target arrangement. Appliances can include a cavity having one or more shaped features or protrusions shaped and/or positioned so as to apply a desired force to a patient's tooth received in the cavity and move the tooth along a desired path or direction.

Abstract: Orthodontic assessment system for treatment planning. Orthodontic assessment may include categorizing a patient's dentition based on predetermined types of malocclusions in a number of orthodontic dimensions. The data is organized in matrices with addresses that characterize aspects of the patient's dentition and that may be used to query the database. In some examples, the one or more treatment goals may be incorporated with data regarding the patient's dentition to generate combined addresses.
