title: Surgical-orthodontic correction of maxillary retrusion by Le Fort I osteotomy and proplast.
abstract: The combined efforts of the orthodontist and surgeon are necessary for successful treatment of most patients with maxillary retrusion. Both the aesthetic and functional manifestations of this dento-facial deformity can usually be effectively treated by maxillary advancement, augmentation of the midfacial region and orthodontics. Treatment planning, pre- and post-surgical orthodontic treatment principles, and surgical considerations in treating 25 adults with maxillary retrusion are described and illustrated. Surgical advancement of the maxilla by Le Fort I osteotomy, proper alignment of the teeth by orthodontics, and augmentation of the paranasal, canine fossae and malar regions with Proplast, were the common denominators of successful treatment.
