Abstract: A palatal arch bar of the removable and adjustable palatal arch wire type disclosed in Goshgarian U.S. Pat. No. 3,792,529 which is improved to have a dual upper arch usage, whereby the arch bar may be applied from the mesial and used as disclosed in said patent to derotate the first permanent molars, and then removed, reversed and reapplied to the molars from the distal to use them as anchor molars in the translation of the upper arch canines. The improved arch bar comprises an arch wire equipped with a fitting or spur adjacent each terminal end of the arch wire that adapts the arch bar for use in bodily retraction of the maxillary permanent canine teeth.

Abstract: A removable orthodontic palatal arch bar for applying rotating, expanding, contracting, intruding and/or torqueing forces to a pair of opposed molars which includes an arch bar of round wire having doubled-over ends receivable by lingual tubes mounted on the molars and a combination locking device and elastic anchoring means extending from the doubled over ends along the gingival and distal sides of the tubes.

Abstract: An orthodontic retainer and retainer wire therefor in which the retainer wire is of one piece pre-formed construction and has a beam portion shaped and dimensioned lengthwise thereof to substantially conform to the chord extending between the points of contact of the upper jaw lateral incisors and the canine teeth adjacent same, together with consecutive vertical and horizontal open loops at each end of the beam portion with the horizontal loops merging into the retainer palatal extensions. The vertical and horizontal loops permit accurate adjustment of the wire beam portion for both tension and correct positioning on the labial side of the teeth. The wire is arranged for controlling the incisors and canines without having to be anchored to any of the teeth while providing for palatal extensions that are to be integrated with the palatal overlay, and that are located to avoid interference with the teeth on occlusion.
