Our patient, a 27-year-old woman, came to Clínica Birbe concerned about the disharmony of her face: she had a receding jaw, a poorly projected chin, an open bite, and a narrow upper jaw that caused excessive gum exposure when smiling. After a detailed study with a 3D scanner, clinical photographs, and functional analysis, we designed a customized treatment that combined presurgical orthodontics, segmented bimaxillary orthognathic surgery, and an advancement mentoplasty. The upper jaw was segmented using a Le Fort I osteotomy into several pieces, allowing us to correct the open bite and precisely widen the maxilla; it was also slightly impacted to reduce the gummy smile. The mandible was advanced with counterclockwise rotation to restore good occlusion and properly project the lower third of the face. Finally, we performed an osseous mentoplasty to achieve a natural, feminine, and proportionate profile. The entire procedure was digitally planned using 3D technology, allowing us to offer maximum precision, predictability, and safety. The result was a functional and aesthetic transformation, with a balanced smile, a harmonious facial expression, and, above all, a patient who finally recognizes and likes herself in the mirror.
