A variety of fixed appliances have been proposed to upright tipped molars. In this design, all teeth as far forward as the canine in the treatment quadrant are included to provide anchorage. The canine on the contralateral side is also linked to the anchor teeth by use of a heavy stabilizing lingual arch. This canine-to-canine stabilizing arch not only increases the anterior anchorage, but also resists buccal displacement of the anchor teeth. Although direct bonded brackets are suitable for all the teeth, it may sometimes be advisable to band the molar. In the simplest of cases, where the premolars and cuspids are only being used for anchorage, edgewise brackets can be placed in the position of maximum convenience where minimum wire bending will be required to engage a passive arch wire. A rigid stabilizing wire, .019 x .025 stainless steel, is placed in the area of the premolars and canine. The molar uprighting is done with a helical uprighting auxiliary spring of .017 x .025 stainless steel wire placed in the auxiliary tube of the molar. The mesial arm of the helical spring should be adjusted to lie passively in the vestibule, and upon activation should hook over the arch wire in the stabilizing segment. It is important that the hook be positioned so that it is able to slide distally as the molar uprights. A slight lingual bend placed in the uprighting spring is needed to counteract the forces that tend to tip the anchor teeth buccally and the molar lingually.
