Zusammenfassung: | The utility model provides a double-designation high-precision preformed angle sliding bracket and an orthodontic appliance, belonging to the field of orthodontic apparatuses. The double-designation high-precision preformed angle sliding bracket comprises a bottom plate and two bracket wings, wherein each bracket wing is provided with two grooves for accommodating arch wires; the two bracket wings are arranged at the same side of the bottom plate. The double-designation high-precision preformed angle sliding bracket and the orthodontic appliance provided by the utility model have the beneficial effects that by virtue of the two grooves in each bracket wing, the forces of the bracket wings suffering from the arch wires are larger, and the relative rotation and sliding between the arch wires and the bracket wings are reduced; meanwhile, the two grooves can be matched with the arch wires to apply torque to the double-designation high-precision preformed angle sliding bracket so that the orthodontics can be more precise, and the operation is also simpler. |
