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.
