Abstract
A labial bow bending device for use in quickly and accurately forming a Hawley retainer or other removable orthodontic appliance. The bending device includes a turret with pins on opposite ends for forming a pair of standardized pre-measured vertical loops in an orthodontic wire for use in a maxillary or mandibular labial bow. A measuring scale is provided on the turret for establishing the distance between the vertical loops during formation of the labial bow such that the distal legs of the vertical loops pass between the canines and first bicuspids of a plaster model of a patient's teeth. The turret also includes a plurality of circular grooves of different diameters for use in forming an incisor section of the labial bow between the vertical loops into a smooth arc that conforms to the curve of the labial surfaces of the incisors on the plaster model.
