The intraoral examination showed a Class II, Division 1 malocclusion, with 1 mm overbite and 3.5 mm overjet. The maxillary arch had a triangular morphology and the mandibular arch was parabolic, in addition to the absence of the clinical crown of the right mandibular first molar. Treatment began with the simultaneous use of ACM and an Essix retainer for anchoring the mandibular arch. During this period, Class II elastics were applied for 5 months, achieving Class I molar and canine relation. Subsequently, MBT .022” metal brackets were used on both arches. The results demonstrated stability over a two-year follow-up period, with patient satisfaction.
