ABSTRACT:
This patent describes a new orthodontic instrument to be used for tying or twisting the ligature wires used to hold the arch wire to the bracket. It also explains the method of use which consists of: twisting the wires, after the ligature wire has been placed on the bracket; tucking the twisted end out of the way; and then breaking the end at the tip of the instrument. The instrument replaces three instruments normally used, by improvements in jaw design to facilitate grasping and centering the wires for spinning, balancing the instrument by general symmetry, and the addition of an extension handle to allow rapid spinning, and tucking of the wire ends as they are broken in a controlled manner, and at a specific place. The instrument thus simplifies, speeds and further improves the application of ligature wires.
