case_images: After assessing the panoramic radiography and teleradiography (Figure 2), the patient was diagnosed with maxillary retrusion, thus causing natural compensatory proclination of upper incisors.

case_images: After installation, an alginate molding was made and forwarded to the production of the pendulum's anchorage unit, where it would be bonded with photoresin (Figure 3).

case_images: A bracket was not bonded to tooth 22 for lack of space in the dental arch (Figure 4). I, with accentuated buccal torque (Figure 4) and decreasing upper and lower crowding. In this step, the pendulum was removed along with the anchorage unit.

case_images: In the tenth month of treatment, the remaining spaces were closed with chain elastics and with the installation of a 0.019'' x 0.025'' steel wire in the upper arch, improving the torque in the first upper molars (Figure 5); a 0.018'' steel wire was installed in the lower arch. Folds (offset) were applied in the area of teeth 33 and 43, seeking the proper lateral movement (Figure 5).

case_images: In the first posttreatment control, one month after the removal of the fixed appliance, the upper anterior teeth were rebonded for the repositioning of tooth 22, which presented lingual relapse (Figure 8) due to the lack of patient cooperation in using the upper removable retainer.
case_images: After 3 months, the fixed appliance was removed again and an upper fixed retainer was produced from tooth 21 to tooth 23.
