Abstract: Laser cutting systems and methods are described herein. One or more systems include a laser generating component, an optical component, a fixture for holding a support with a part positioned on the support, and a control mechanism for adjusting at least one of the laser generating component, the optical component, and the fixture such that a ratio of a laser energy applied to the part and a part material thickness is maintained within a predetermined acceptable range at each point along a cut path to cut through the part while maintaining the integrity of the support. Other systems and methods are disclosed herein.

Abstract: Provided herein are orthodontic devices and methods for patients whose orthodontic devices are causing a lisp. The device can comprise an aligner configured to fit over a patient's dental arch and comprising an occlusal surface section positioned over an occlusal surface of the patient's teeth. The aligner can comprise a barrier portion extending laterally and adjacent to a region of the dental arch, the barrier portion allowing the patient's tongue to form a seal against the barrier portion when the patient is speaking while wearing the device.

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: This disclosure provides polymeric materials comprising polymer crystals, methods and resins for making the same, and objects and appliances made from said polymeric materials. Polymeric materials having polymer crystals provide favorable properties, such as enhanced durability and rigidity. This disclosure also provides polymeric materials comprising a crystalline phase comprising at least one polymer crystal, as well as an amorphous phase comprising at least one amorphous polymer. The crystalline phase can confer rigidity to the polymeric material, while the amorphous phase can confer elasticity and flexibility.

Abstract: A non-transitory medium includes instructions for generating a three-dimensional virtual model of an intraoral object by receiving surface scan data of the intraoral object while changing a position of at least one lens of focusing optics of an intraoral scanner, wherein the surface scan data comprises data for a plurality of points of the intraoral object, and adjusting the data for one or more of the plurality of points to compensate for one or more inaccuracies associated with changes of a shape of a focusing surface. A three-dimensional virtual model of the intraoral object is generated using the adjusted data.

Abstract: A method of generating a virtual 3D model of a dental arch is provided. The method includes receiving intraoral scans of a dental arch, determining a first depth of a first intraoral 3D surface in a first intraoral scan, and determining a second depth of a second intraoral 3D surface in the first intraoral scan, and wherein there is a fixed distance between the first intraoral 3D surface and the second intraoral 3D surface in the first intraoral scan. The method further includes stitching together the intraoral scans and generating a virtual 3D model of the dental arch from the intraoral scans, wherein the fixed distance between the first intraoral 3D surface and the second intraoral 3D surface is included in the virtual 3D model.

Abstract: A method includes forming a plastic orthodontic aligner having a plurality of cavities shaped to receive at least portions of a plurality of teeth of a patient. A first segment of the plastic orthodontic aligner corresponds to a first subset of the plurality of cavities for moving a first subset of the plurality of teeth of the patient. A second segment of the plastic orthodontic aligner corresponds to a second subset of the plurality of cavities. The method further includes removing a first portion of the plastic orthodontic aligner between the first and second segments of the plastic orthodontic aligner to form a connector to minimize force transmission between the first and second segments. The connector is configured to be disposed along one or more additional teeth to span a gap between the first and second segments without exerting a clinically significant force on the one or more additional teeth.

Abstract: The disclosed systems and methods for anonymizing clinical data may include receiving representation data corresponding to a body part. The representation data may include a clinically relevant region and an anonymization region. The method may include extracting, from the representation data, clinical representation data corresponding to the clinically relevant region of the representation data and generating artificial representation data corresponding to the anonymization region of the representation data. The method may further include creating, based at least on the clinical representation data and the artificial representation data, anonymized representation data that substantially preserves the clinically relevant region. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The present disclosure provides methods, devices, and systems for the creation of attachments for use with dental appliances and changeable shaped attachments. For instance, an attachment template tray for creating and placing attachments used in moving teeth of a patient can include an attachment template tray body having a first surface shaped to conform to the contours of exterior surfaces of teeth of a patient and including a portion of the first surface that provides a cavity to form the exterior surfaces of an attachment that is to be attached to the exterior surface of one of the teeth and an integrated light source, power source, and actuation mechanism on the body of the attachment template tray, wherein the power source provides power to the light source when the actuation mechanism is actuated.

Abstract: A machine learning model is trained to define bounding shapes around teeth in images. The machine learning model is trained by receiving a training dataset comprising a plurality of images, each image of the plurality of images comprising a face and a provided bounding shape around teeth in the image. The training dataset is input into an untrained machine learning model. The untrained machine learning model is trained based on the training dataset to generate a trained machine learning model that defines bounding shapes around teeth in images, wherein for an input image the trained machine learning model is to output a mask that defines a bounding shape around teeth of the input image, wherein the mask indicates, for each pixel of the input image, whether that pixel is inside of a defined bounding shape or is outside of the defined bounding shape.
