Abstract
An orthodontic instrument includes a pair of complementary mating die movable together and apart for forming a Z-shaped bend in an orthodontic arch wire. A Z-shaped bend in an orthodontic arch wire is utilized in conjunction with an orthodontic appliance for applying force to a tooth through a bracket thereon to change its inclination and/or rotation respecting the long axis of the tooth, e.g., to upright an angulated tooth or derotate a rotated tooth. Different embodiments of the instrument are utilized in a sideways or an end-on orientation relative to the arch wire to form a Z-bend therein in situ in a patient's mouth, or may operate on the arch wire outside the mouth.
