Abstract: The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment formation structures. One dental appliance includes a body having a first surface shaped to abut an exterior surface of a tooth and a well portion of the first surface shaped to form an attachment that is to be attached to the exterior surface of the tooth, a release layer formed over a surface of the well to allow the attachment to be removed from the well, and an attachment material that is used to form the attachment positioned within the well.

Abstract: Systems and methods for modeling a patient's tooth are provided. In some embodiments, a system includes a scanner configured to generate image data of a partial portion of a crown of a patient's tooth, a memory, and one or more processors operably coupled to the scanner and to the memory. The one or more processors can be configured to perform operations including: receiving the image data from the scanner, generating a digital representation of the crown of the patient's tooth based on the image data, selecting a digital tooth template having a crown portion, generating a morphed crown portion based on the crown portion of the digital tooth template, and generating a digital patient crown model by combining the morphed crown portion with the digital representation of the crown of the patient's tooth.

CPC classification number: A61C7/08
Abstract: A dual aligner assembly including a plurality of aligners, including a first aligner and a second aligner. The first aligner has a first shape corresponding to a set of target tooth positions and applies an orthodontic force against a set of target teeth. The first orthodontic force generates movement of the set of target teeth to the set of target tooth positions. The second aligner has a second shape corresponding to a combination of current tooth positions of the set of target teeth, the set of target tooth positions, and a thickness of the first aligner. The second aligner partially encloses the first aligner and provides an anchor for at least a portion of the first aligner. Via the anchor, a combination of the first aligner and the second aligner provides an orthodontic force that prevents the set of target teeth from moving to unwanted tooth positions during orthodontic treatment.

Abstract: Systems for modeling a patient's teeth are provided. In some embodiments, a system includes a scanner operable to capture a scanned image of at least a portion of a surface of a first crown component of a first patient tooth, and to generate scanned image data representing a partial portion of the surface of the first crown component. The system can also include a processor configured to create a digital data set representing the scanned image data, select a digital tooth template that includes a second digital crown portion corresponding to the scanned image, create a morphed digital tooth crown model based on the selected digital tooth template, and merge the morphed digital tooth crown model with the digital data set representing the scanned image data of the first patient tooth to generate a complete digital patient tooth crown model.

Abstract: A scan model that is a mathematical model to simulate an imaging process performed by an x-ray imaging device that created a two-dimensional x-ray image of at least one tooth is generated. The scan model uses an initial estimate of one or more parameters of the x-ray imaging device. The one or more parameters include a scan angle parameter indicative of a scan angle of the x-ray imaging device. A two-dimensional contour of a three-dimensional model is adjusted to cause a first component of the two-dimensional contour to approximately align with a second component of the two-dimensional x-ray image. The scan model is calibrated based on data obtained from adjusting the two-dimensional contour.

Abstract: An orthodontic appliance may include an outer shell having a plurality of cavities shaped to receive the patient's teeth and generate one or more of a force or a torque in response to the appliance being worn on the patient's teeth. The orthodontic appliance may also include an inner structure having a stiffness different than a stiffness of the outer shell. The inner structure can be positioned on an inner surface of the outer shell in order to distribute the one or more of a force or a torque to at least one tooth received within the plurality of cavities.

Abstract: The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.

Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.
