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: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).

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: The present disclosure provides computing device implemented methods, computing device readable media, and systems for adjustment of tooth position in a virtual dental model. Virtual dental modeling can include detecting space and/or collision between posterior teeth of an upper jaw and posterior teeth of a lower jaw in a virtual dental model that has been set in a preliminary target position. An energy function can be defined including the space and/or collision, tooth root movement, and align points. Weights can be assigned for each variable in the energy function. A position of the posterior teeth of the upper jaw and the posterior teeth of the lower jaw can be adjusted in six degrees of freedom to minimize the energy function. The detection, definition, assignment, and adjustment can be repeated until the energy function converges. The weights can be adjusted to reduce the space and/or collision.

Abstract: Methods for fabricating dental appliances and associated systems are provided. In some embodiments, a method includes defining a plurality of object cross-sections of a dental appliance, and sequentially polymerizing the plurality of object cross-sections to create the dental appliance. The dental appliance can include an outer shell having a plurality of teeth-receiving cavities, and an inner structure coupled to an inner surface of the outer shell. The outer shell can have a first stiffness, and the inner structure can have a second stiffness less than the first stiffness. The sequential polymerization can include integrally forming the outer shell concurrently with the inner structure.
