CASE REPORT Fig. 6 Fig. 7 Fig. 8 Fig. 9 Fig. 10 Fig. 11 ᕢ Once molars distalized, appliance is removed and normal tip-edge mechanics are used to finish the case (Fig. 15). ᕣ Finished case (Fig.16). Fig. 12 Fig. 13 Fig. 5 in a full step molar Class II relationship? After discussing the case with the parents, we decided to attempt to distal-ize the molars with a Pendulum appliance. Treatment of Case 1 ᕡ Placed appliance (Fig. 6). ᕢ Five months later, molars distalized to a Class I rela-Fig. 14 Fig. 15 tionship (Fig. 7). ᕣ Removed appliance. There is plenty of space for the upper canines to be moved into place (Fig. 8). ᕤ Now, we continue treatment with normal Stage I tip-edge mechanics. An upper .016 niti wire was placed to move canines into place (Figs. 9, 10, 11). Fig. 16 Case 2 Dr. Bert Vasut diagnosed the following: ᕡ Trapped out upper second bicuspids. ᕢ Retained upper deciduous canines. ᕣ Mild posterior crossbite. Treatment of Case 2 ᕡ Start with Pendex appliance to distalize molars. Note: Appliance can also be fabricated with a jack screw to correct posterior cross-bites. www.orthodontics.com May/June 2011 23
