CASE STUDY Fig. 18 ᕦ No elastics or bite turbos were used in this case. Total treatment time was about 12 months. (Fig. 22) Case 3 Example This case involves an adult female who presented with maxil-lary and mandibular spacing and a 60 percent overclosed bite (Fig. 23). Her model discrepancy was +2, and her Witts was +2.8 (skele-tal Class I), and a total discrepancy of +8 dictated non-extraction treatment. The posterior crossbite will be left because the only way to correct it is through orthog-nathic surgery. (Fig. 23) Fig. 19 ᕡ We started the case with upper and lower .014 flat niti wires to level and align teeth. A button was placed on the lower left 5 to unrotate it. I intentionally did not bracket the lower canines because the patient would have hit hard on the brackets. Once the bite is open, we will bracket these teeth. (Fig 24) Fig. 20 ᕢ Two months later, we finished placing the lower brackets, and the upper arch went to an .016 reverse curve niti wire to open the bite.
