Abstract: A syringe for dispensing a flowable material. The syringe has a cartridge with a cartridge front end and at least a first dispensing nozzle arranged at the cartridge front end. The syringe further has closure for openably closing the first dispensing nozzle. The closure includes a cap and at least a first seal. The cap is telescopically placeable on the cartridge front end. The closure or the cartridge has a first magnet for establishing a magnetic attraction between the closure and the cartridge. In a situation in which the closure is placed on the cartridge front end, the closure and the cartridge can be positioned in a sealing position in which the first seal spaces the cap and the cartridge front end away from each other against a magnetic attraction that urges the cap and the cartridge toward each other.

Abstract: A removable dental appliance may include an appliance body at least partially surrounding a plurality of teeth and an interproximal reinforcement. The appliance body may include a first shell shaped to engage a first tooth and a second shell shaped to engage a second tooth. The interproximal reinforcement extends from a first gingival edge on a labial side of the appliance body along an interproximal region between the first tooth and the second tooth to a second gingival edge on a lingual side of the appliance body. The interproximal reinforcement is configured to engage at least one of a lingual surface or labial surface of the first tooth below a height of contour to enable the appliance body to cause movement of the first tooth toward a desired position.
