Figure 12. An omega loop placed against the molar buccal tube to prevent mesial slippage of the distally-driven upper molars. The leveling arch is .014 round wire.

Figure 13. When a resilient archwire (nickel titanium) is needed to level the upper arch, a pinch-on stop is placed following archwire placement. When placed against the molar tube, the stop will help prevent forward molar movement.

Figure 14. Molars are overtreated in this mild Class II malocclusion. The upper buccal segments are retracted using stops at the uppe molars.

Figure 15. The upper buccal segments are fully retracted, moving the space from the molar region mesial to the upper cuspids. The upper incisors are commonly retracted and intruded using the Reverse Curve TMA (TM) "T" looped archwire.
