CASE STUDY Fig. 6 Fig. 7 Treatment Objectives ᕡ Level and align maxillary and mandibular arches ᕢ Establish/maintain Class I molar relationship ᕣ Establish/maintain appropri-ate molar inclination ᕤ Eliminate tooth rotations ᕥ Establish/maintain appropri-ate curve of Spee ᕦ Establish tight contacts ᕧ Retain overall results with an upper Essix retainer and a lower bonded 3-3 lingual retainer. Treatment plan ᕡ Band U/L 6’s and 7’s ᕡ Bracket U/: 5-5 Estimated Treatment Time: 18-24 months Treatment Orthodontic treatment began. In the first month, consent documents were reviewed with parents and separators were placed between the interproximals of the first molars. The first molars were banded, the premolars and anterior teeth brack-eted with .022 slotted brackets (Modified Roth prescription), and .012 Nitinol arch wires were initially placed. Composite pads were placed on the occlusals of the first molars to open the bite initially to prevent patient from biting on premolar brackets. As the second molars were not in full eruption, I delayed band-ing and progressing to a .014 Nitinol arch wire until the following adjustment. The follow-ing adjustment appointment, .014 Nitinol arch wires were placed and remained in the patient for approximately two months. In month three, a .018 Nitinol arch wire to round out the arches further was placed. Following that, .020 stain-less steel arch wires in month five were placed. No accentuated curve in the upper and no reverse curve in the lower arch was placed due to esthetically appropriate overbite and vertical dimension of occlu-sion. The molar bite pads that were initially placed were removed. The Fig. 8 24 Summer 2019 JAOS
