ORTHODONTIC LIGATURE SYSTEMS AND METHODS

摘要

Ligature systems retain an arch wire within a slot of an orthodontic bracket. According to some embodiment, the ligature system retains an arch wire within a slot of an orthodontic bracket by means of a retaining element which is capable of being unidirectionally mechanically locked within the slot of the orthodontic bracket to retain an arch wire therewithin. The retaining element may comprise a pair of opposed outwardly projecting retaining edges. In some embodiments, the retaining element comprises a planar or curved retaining plate. The ligature system may include a central block in which the retaining plate is embedded such that the retaining edges extend outwardly therefrom. The ligature system may also include spike protruding outwardly from such central block so as to engage with the arch wire positioned subjacently thereto. In some embodiments of the invention, the retaining element is integral with the arch wire, while in other embodiments of the invention, the retaining element is integral with the slot in the orthodontic bracket. A dispenser may also provided according to the invention for dispensing individual ligature systems.
