case_images: Initial facial and intraoral photographs of our patient who was diagnosed with angles Class I malocclusion, a skeletal Class III jaw relationship with a concave profile, unilateral anterior crossbite, open bite, distorted Anterior segment with crowding, occlusal distortion, a left-sided cleft lip and palate and oronasal fistula at 13 years of age

case_images: She had a Class I molar relationship on the right and left sides, anterior crossbite with reverse overjet of 4 mm, Unilateral open bite on the left side, palatally positioned 12, partially erupted 22 and incisors are in Class III relationship [Figure 1]. Superimposition of the pre- and post-treatment lateral cephalograms showed a linear movement of maxillary anterior segment by 7 mm [Figure 9 and Table 1].

case_images: Left lateral incisor was in the cleft region; hence, very mild forces are used to derotate it [Figure 8].

case_images: Superimposition of the pre- and post-treatment lateral cephalograms showed a linear movement of maxillary anterior segment by 7 mm [Figure 9 and Table 1]. The follow-up retention after 24 months showed a stabilized skeletal pattern with no signs of relapse [Figures 9 and 10].
