Abstract: Methods and apparatuses (including systems and devices), including computer-implemented methods for segmenting, correcting and/or modifying a three-dimensional (3D) model of a subject's oral cavity to determine individual components such as teeth, gingiva, tongue, palate, etc., that may be selective and/or collectively digitally manipulated. In some implementations, artificial intelligence uses libraries of labeled 2D images and 3D dental models to learn how to segment a 3D dental model of a subject's oral cavity using 2D images, height map and/or other data and projection values that relate the 2D images to the 3D model. As noted herein, the dental classes can include a variety of intra-oral and extra-oral objects and can be represented as binary values, discrete values, a continuum of height map data, etc. In some implementations, several dental classes are predicted concurrently.

Abstract: A method comprises receiving, by a processing device, clinical data of a first state of one or more dental arches of a patient. The method further comprises determining, by the processing device, one or more stages of an orthodontic treatment plan for correcting the one or more dental arches based on processing of the clinical data. Determining a stage of the orthodontic treatment plan comprises determining one or more actions to be performed with respect to the one or more dental arches and determining a target state of the one or more dental arches that is predicted to result at least in part from the one or more actions.

Abstract: Various aspects described herein relate to compositions comprising silk fibroin particles and methods of using the same, as well as devices and methods of delivering such compositions. The compositions described herein are suitable for injection into a site of defect in a soft tissue to provide bulking and/or augmentation effect to the soft tissue.

Abstract: Conduit coupling devices comprise a body configured to be selectively attached to engage an outer surface of a conduit; and an elongate connecting member extending from the body or configured to selectively extend from the body. Systems comprise at least two conduit coupling devices. Methods comprise attaching a first conduit coupling device to a first conduit; attaching a second conduit coupling device to a second conduit; operatively attaching the first conduit coupling device to the second conduit coupling device; translating the first conduit coupling device and the second conduit coupling device toward each other to operatively position the first conduit relative to the second conduit; and clamping the first conduit to the second conduit.

Abstract: A computing device comprises a memory to store instructions and one or more processors operatively coupled to the memory. Execution of the instructions causes the one or more processors to calculate a quality metric for a region of interest in a received image of a face of a person that comprises a current dentition of the person, wherein data for pixels inside of the region of interest is used to calculate the quality metric, and wherein data for pixels of a second region that is outside of the region of interest is not used to calculate the quality metric; determine whether the quality metric satisfies a criterion; and responsive to determining that the quality metric satisfies the criterion, generate a modified version of the image, wherein the current dentition of the person is replaced with a post-treatment dentition of the person in the modified version of the image.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for optimizing a process of manufacturing a product. In one aspect, the method comprises repeatedly performing the following: i) selecting a configuration of input settings for manufacturing a product, based on a causal model that measures causal relationships between input settings and a measure of a quality of the product; ii) determining the measure of the quality of the product manufactured using the configuration of input settings; and iii) adjusting, based on the measure of the quality of the product manufactured using the configuration of input settings, the causal model.

Abstract: A method of applying a lubricant onto a carriage box of a collimator includes: providing a mixture having a lubricant and a solvent; applying an amount of the mixture that includes a predetermined quantity of the lubricant onto a first set of guide rails at a first side of the carriage box; and removing the solvent from the mixture to leave the lubricant adhering to the surface. A kit for lubricating a collimator includes: a container housing a lubricating mixture having a lubricant mixed in a solvent; wherein a quantity of the lubricant is predetermined based, at least in part, on a first surface area of a first set of guide rails at a first side of a carriage box, a second surface area of a second set of guide rails at a second side of the carriage box, or both the first surface area and the second surface area.

Abstract: A system includes a beam filter positioning device including a plate configured to support one or more beam filters, and one or more axes operable to move the plate relative to a beam line. A control mechanism is coupled to the one or more axes for controlling the movement of the axes and configured to automatically adjust the position of at least one of the one or more beam filters relative to the beam line.
