Abstract: A method, apparatus, electronic device and a storage medium for controlling media content are provided. In the method, target media content is played in a first region of a media content playback page. In response to a comment display operation for the target media content, comment information of the target media content is displayed in a second region of the media content playback page. In response to a target trigger operation on the media content playback page, the playing of the target media content is paused, and/or the comment information of the target media content is kept displaying.

Abstract: Embodiments of the present disclosure disclose an information display method and apparatus, a device, and a storage medium. The method includes: in response to that a target preset entry on a target interface is triggered, determining a target display mode corresponding to the target preset entry; and displaying, on a preset information display interface, associated information corresponding to preset content according to the target display mode, where the target interface is used to display the preset content and includes at least two preset entries for triggering the display of the preset information display interface, the at least two preset entries include the target preset entry, and different preset entries correspond to different display modes of the preset information display interface.

Abstract: Conformable transfer devices and micro-transfer printing methods are described. In an embodiment, a conformable transfer devices includes first and second arrays of transfer heads with differential lengths to support a micro-transfer printing sequence including a single pick operation and multiple placement operations.

Abstract: Methods and systems for generating support structures for additively manufactured objects are described herein. In some embodiments, a method includes receiving a digital representation of a dental appliance configured to implement a treatment stage of a treatment plan for a patient's teeth. The method can include generating a support structure arrangement configured to support the dental appliance during an additive manufacturing process. The support structure arrangement can be generated using a machine learning model. The machine learning model can be trained on a training data set including appliance data representing geometries of a plurality of dental appliances, support structure data representing geometries of a plurality of support structure arrangements, and outcome data representing outcomes of the additive manufacturing process for the plurality of dental appliances with the respective support structure arrangements.

Abstract: Dental appliances and methods for expanding the lower dental arch. The appliances may be removable mandibular expander devices for efficient arch expansion while being comfortable to wear and easy to use. The appliances may include a lingual portion that is shaped and sized to apply an expansion force to lingual surfaces of one or more teeth. The shape and size of the lingual portion may be configured to distribute the forces among posterior and/or anterior teeth.

Abstract: Apparatuses (e.g., distalizers) and methods for distalizing a subject's teeth while preventing or reducing undesirable tipping and/or rotation of the teeth. The distalizer apparatuses may include tooth engagement regions shaped to accommodate molars, canines and/or premolar teeth, may include a transpalatal region extending between engagement regions having an anterior edge that is posterior to a premolar region of the first tooth engagement region, and may include an attachment site for an elastic band on the outer buccal surface.

Abstract: Methods and apparatuses for retaining or treating a dental arch to apply a lateral expansion force to a lower jaw while permitting the extrusion of one or more teeth may include the use of a maxillary dental appliance device and/or a mandibular dental appliance device including projection regions extending from the occlusal surfaces of the device to apply a laterally outward expansion force.

Abstract: A method for use in additively manufacturing an orthodontic aligner may include receiving a digital model of an aligner, processing the digital model of the aligner to modify the digital model based on predicted deviations during fabrication to generate a first updated digital model of the aligner, determining that whether the predicted deviations of a physical aligner additively manufactured based on the first updated digital model of the aligner are acceptable, and outputting the first updated digital model of the aligner for fabrication of the physical aligner by additive manufacture of the physical aligner.
