Abstract: Methods for manufacturing objects are provided herein. In some embodiments, a method includes receiving a digital data set representing an object, and applying energy to a curable material based on the digital data set to form the object. The object can include at least two object portions formed from the curable material using different energy application parameters. The method can further include removing residual curable material from the object. A different amount of the residual curable material can be removed from each of the at least two object portions. After the residual curable material is removed, the at least two object portions can each have different material properties.

Abstract: Orthodontic devices such as aligners, palatal expanders, retainers, and dental implants can be used to adjust the position of teeth and to treat various dental irregularities. To help the clinician or doctor (i.e., orthodontist) design and plan the subject's treatment plan, a 3D digital model of the subject's teeth, dentition, and gingiva can be constructed from a 3D scan of the subject's mouth, teeth, dentition, and gingiva. The 3D model of the subject's teeth and dentition can be displayed graphically to the doctor on a display using a computing system with memory and software.

Abstract: The present invention provides protective repositioning appliances, accommodating mouth guards, and covering guards that protect an orthodontic patient against impact-induced injuries, as well as related systems and methods. A protective appliance can include teeth receiving cavities shaped to receive and reposition a patient's teeth and can include an occlusal portion having an impact-absorbing compliance. An accommodating mouth guard can include teeth receiving cavities shaped to accommodate a patient's teeth from a first arrangement to a second arrangement and can include an occlusal portion having an impact-absorbing compliance. A covering guard can include a guard segment that covers at least a portion of an appliance. The combination of a guard segment and an appliance can provide an occlusal compliance that absorbs impacts.

Abstract: Embodiments include receiving intraoral scan data comprising a plurality of intraoral images of a dental site generated during scanning of the dental site by an intraoral scanner, a plurality of ink markings each comprising a pattern of ink having been temporarily stamped or tattooed onto a gingival surface at the dental site prior to the scanning of the dental site, wherein at least two intraoral images of the plurality of intraoral images comprise representations of one or more ink markings of the plurality of ink markings. Embodiments further include performing registration between the plurality of intraoral images based at least in part on the one or more ink markings, generating a three-dimensional (3D) model of the dental site using the plurality of intraoral images that have undergone registration, and outputting the generated 3D model to a display.

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 determines an updated orthodontic treatment plan based on one or more differences between the actual condition of the patient's dental arch and the planned condition of the patient's dental arch determined from the comparing. The processing device generates one or more three-dimensional (3D) models for one or more new orthodontic aligners in accordance with the updated orthodontic treatment plan.

Abstract: The present disclosure includes methods, systems, and devices for prioritization of three dimensional dental elements. One method for prioritizing three dimensional dental elements includes receiving a virtual initial dental data set (IDDS) of teeth having spatial information regarding the positions of a number of teeth in the virtual IDDS with respect to each other for presentation of the teeth in a virtual three dimensional space to be viewed on a user interface, setting prioritization values of a number of elements of one or more of the number of teeth, and prioritizing the number of elements to be selected by a user based upon their prioritization values.

Abstract: Laser cutting systems and methods are described herein. One or more systems include a laser, an optical component, a fixture for holding a support with a part positioned on the support, and a controller. The controller is configured to identify a cut path for trimming excess material from a dental appliance, determine adjustment instructions for adjusting a focal length of the laser to cut along the cut path, and trim the excess material from the dental appliance along the cut path with the laser. The focal length is adjusted by adjusting at least one of: the laser, the optical component, and the fixture, and while moving the fixture at a constant speed relative to the laser to avoid increasing a brittleness of a polymer material of the dental appliance along the cut path.
