The oral hygiene was fair but needed improvement prior to orthodontic treatment. All teeth from the left permanent second molar to the right have erupted in both the upper and lower arches. The patient had carious lesions in both upper first molars, upper left second molar and lower left first molar. The maxillary arch was spaced with a midline diastema. Furthermore, there was mild lower labial segment crowding (4mm). The incisor relationship was Class ІІ division 1, the overjet was 12 mm whereas the overbite was increased and complete to the palate and causing trauma to the palatal mucosa. The centrelines were coincident and the buccal segment relationship was ½ unit Class ІІ on both sides (Figure 2).
