An 18-year-old male sought orthodontic consultation due to dissatisfaction with the appearance of his upper front teeth, which were positioned behind the lower incisors, resulting in posterior dental compression. Cephalometric analysis revealed a retruded maxilla with a downward and backward mandibular rotation, leading to an anterior crossbite. Treatment began with a rapid maxillary expander and face mask to correct the maxillary crossbite. Posterior bite ramps were placed on the lower first molars to disengage the bite, facilitate crossbite correction, and prevent upper molar extrusion during expansion and forward movement of the upper incisors. This was followed by comprehensive fixed orthodontic treatment using the 0.022 MBT system. Utilizing a rapid maxillary expansion device combined with a face mask a simple and easily adjustable appliance enabled the patient to achieve a functional occlusion and an improved facial appearance, thereby enhancing self-esteem and confidence.
