Abstract: Methods and apparatuses for generating a model of a subject's teeth. Described herein are intraoral scanning methods and apparatuses for generating a three-dimensional model of a subject's intraoral region (e.g., teeth) including both surface features and internal features. These methods and apparatuses may be used for identifying and evaluating lesions, caries and cracks in the teeth. Any of these methods and apparatuses may use minimum scattering coefficients and/or segmentation to form a volumetric model of the teeth.

Abstract: The example systems, methods, and/or computer-readable media described herein help with design treatment plans for orthodontic treatments. Treatment templates expressed according to treatment domain-specific protocols may be processed to provide treatment planning software, including automated or real-time treatment planning software, that accommodates treatment preferences of a practitioner and/or patient data relevant to a treatment plan. These methods and systems may be also be useful for planning, designing and producing as series of dental appliances (e.g., aligners).

Abstract: Described herein are apparatuses and methods for confocal 3D scanning. The apparatus can comprise a spatial pattern disposed on a transparent base and a light source configured to provide illumination to the spatial pattern and an optical system comprising projection/imaging optics having one or more lenses and an optical axis. The projecting/imaging optics may be scanned to provide depth scanning by moving along the optical axis.

Abstract: A 3D virtual model of an intra oral cavity in which at least a part of a finish line of a preparation is obscured is manipulated in virtual space by means of a computer or the like to create, recreate or reconstruct finish line data and other geometrical corresponding to the obscured part. Trimmed virtual models, and trimmed physical models, can then be created utilizing data thus created. The virtual models and/or the physical models may be used in the design and manufacture of copings or of prostheses.

Abstract: The present disclosure provides methods, devices, and systems for adjusting a tooth position. A system for adjusting a tooth position can include an attachment configured to be attached to a tooth to be moved, a dental appliance including a guide slot configured to receive the attachment and to define an adjustment trajectory of the tooth, and an adjustment band to generate force on the tooth to move the tooth along the adjustment trajectory.

Abstract: The present disclosure provides computing device implemented methods, apparatuses, and computing device readable media for confocal imaging using astigmatism. Confocal imaging can include receiving an image of a portion of an object captured by a confocal imaging device having a particular astigmatic character, determining an image pattern associated with the image, and determining a distance between a focus plane of the confocal imaging device and the portion of the object based, at least in part, on information regarding the image pattern. Confocal imaging can also include receiving data representing an image pattern associated with an image of an object captured by a confocal imaging device having a particular astigmatic character and having an image sensor with a plurality of pixels, and determining a positional relationship between the object and a focus plane of the confocal imaging device based on a distribution of the diffraction pattern over a portion of the plurality of pixels.

Abstract: A method and system for inspecting a customized orthodontic aligner for manufacturing defects are described. The method includes obtaining images of the customized orthodontic aligner, determining a digital file associated with the aligner, the digital file including a digital model of a mold used during manufacture of the customized orthodontic aligner, determining an inspection recipe for the aligner, determining an intended property for the customized orthodontic aligner by digitally manipulating the digital model of the mold, determining an actual property of the customized orthodontic aligner from the images, determining whether there is a manufacturing defect in the customized orthodontic aligner by comparing the intended property with the actual property, and outputting an output associated with the determination of whether there is a manufacturing defect.

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.
