Abstract: Medical devices have a polymeric nanocomposite treatment portion configured for contact with a treatment site within an oral cavity of a user and configured for operative communication with a controller. The polymeric nanocomposite treatment portion has a mucosal contact layer comprising a biocompatible polymer and defining a plurality of pores therethrough; a continuous support layer comprising a biocompatible polymer; an electronic network layer between the mucosal contact layer and the continuous network layer; and a means for applying pressure to the treatment site. The electronic network layer has carbon nanostructures and has a quantum micro-chiplet QMC or an octagonal quantum micro-chiplet integrated with a photonic integrated circuit. The electronic network layer is in operative communication with the controller and the power source. A pressure sensor that measures growth pressure is present and is positioned at the treatment site.

Abstract: A system for repositioning teeth a patient from an initial tooth arrangement to a final tooth arrangement includes a plurality of incremental position adjustment appliances, each having an arrangement of cavities shaped to receive and reposition teeth of the patient. The cavities in at least one appliance in the system have a different geometry than that of at least one other appliance in the system. At least some of the appliances in the system are successively worn by the patient to exert force on at least one tooth and move the teeth of the patient from a first arrangement to a successive arrangement different from the first arrangement. The system includes a first multilayer shell with a bending stiffness factor less than about 0.1 GPa*mm3 and an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm3.

Abstract: A temporary alignment system and method for holding a dental coping to an implant abutment using the same threads in the abutment that are used for definitive attachment are disclosed. The disclosed temporary fasteners initially orient and hold a coping against an abutment with a force along the same axis as the semi-definitive screw. The aligned coping can be picked-up in a closed-tray impression process without unscrewing the temporary fastener. Embodiments include threaded posts that release copings from the abutment through axial forces. Some embodiments include a threaded post with separable cap that is picked-up with the coping. Methods for converting an existing prosthesis for screw attachment to implants in a single visit and digital capture of the converted prosthesis are described.

Abstract: A jaw implant (1) having at least one approximately U-shaped hole strip (2), which carries fixing holes (3) spaced apart from one another. In the jaw implant (1), in the space between adjacent fixing holes (3) there are provided cross-sectional weaknesses (4) for cutting the at least one hole strip (2) to length. The at least one hole strip (2) has, in a partial region (8) situated at a distance from the free ends (6, 7) of this hole strip (2), in the region of every fixing hole (3) having an internal screw thread for fixing a dental prosthesis, a cross-sectional widening (9) which increases the longitudinal extension of this fixing hole (3).

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.
