CASE STUDY Expanded upper wire to correct posterior crossbite. Treatment time: 16 months Final Photos of Case 1 (Fig. 6) Final Ceph numbers Lower 1 to apo +2.3 (started with +7) Witts -7.1 (started with -9) Patient and family were extremely happy with results. Case 2: Patient is 16-year-old male Fig. 6 The patient’s chief complaint was that he wants his underbite corrected and teeth straightened. (Fig. 7) E-Plane -3/+1 Model discrepancy +.5 mm Total discrepancy of -1.5 mm (indicating a non-extraction case) Case 1 Treatment Plan We had an oral surgery consultation for possible orthognathic surgery, but the patient declined surgery. At that point, we decided to take out failing Maryland Bridge and treat case as a single-tooth extraction case, knowing that we will not get perfect results but a much improved result. Stage I Braces (Fig. 3) Molar tubes on first molars. Bracketed anterior teeth. Upper and lower .016 ss wire with 30 degree bite opening bends, 2 oz. Class III elastics. Removed failing Maryland bridge and placed plastic pontic on orthodontic wire. Made pontic too small intentionally to close space. As space closes, will shave down pontic mesial-distally. Stage II (Fig. 4) Patient no longer in an under bite Bracketed bicuspids Removed pontic so could finish closing space Upper and lower .016 SS wires 2 oz. class III elastics Treatment time: 7 months Stage III (Fig. 5) Upper and lower .021 x .025 rectangular wires Lower E-link from 3-3 to close space 4 oz. boxing elastics worn at night to settle bite 26 Summer 2015 JAOS Fig. 7 Fig. 8
