Abstract: Systems, methods, and devices for producing orthodontic appliances are provided. In one aspect, an orthodontic appliance comprises an outer shell comprising 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 can comprise 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: 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: A method and system generate 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. The scan model uses an initial estimate of one or more parameters of the x-ray imaging device to simulate the imaging process on a three-dimensional model. The method and system generate the two-dimensional contour of the three-dimensional model based on the scan model that uses the initial estimate of the one or more parameters of the x-ray imaging device. The method and system adjust the two-dimensional contour 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 method and system calibrate the scan model based on data obtained from adjusting the two-dimensional contour.

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.

Abstract: Methods and systems for generating a three-dimensional occlusogram are disclosed. One method includes determining a virtual three dimensional (3D) mesh model object of at least one tooth of a patient and displaying the determined virtual 3D mesh model object of at least one tooth of a patient wherein the 3D mesh model object includes a plurality of data sets associated with a set of occlusal information for the at least one tooth of the patient.

Abstract: A method may include generating a comparison of one or more anatomical reference shapes and one or more surface features on a planned dentition model with a corresponding one or more anatomical reference shapes and one or more surface features on a tracking dentition model using a coarse to fine volume 3D array to represent one or both of the plan model and the tracking model to minimize distances between teeth represented in the plan model and corresponding teeth represented in the tracking model. The method may also include detecting one or more positional differences between the anatomical reference shapes and surface features of the plan model and the corresponding anatomical reference shapes and surface features of the tracking model based on the comparison and generating a modified treatment plan based on the one or more detected positional differences.

Abstract: Methods for designing orthodontic appliances for repositioning a patient's teeth are provided. In some embodiments, a method includes determining a movement path to move one or more teeth from an initial arrangement to a target arrangement, determining a force system to produce movement of the one or more teeth along the movement path, and determining an appliance geometry for an orthodontic appliance configured to produce the force system. The orthodontic appliance can include an outer shell comprising a plurality of teeth-receiving cavities and an inner structure positioned on an inner surface of the outer shell. The inner structure can have an elastic modulus different than an elastic modulus of the outer shell. The method can also include generating instructions for directly fabricating the orthodontic appliance using a layer-by-layer additive manufacturing technique.
