Unilateral expansion of a narrow mandibular dental arch combined with bimaxillary osteotomies in a patient with hypoglossia
چکیده انگلیسی

A 23-year-old female with hypoglossia, who had a narrow mandibular dental arch, was treated using the gradual expansion technique. Three lower incisors were missing and the right molar occlusion showed a scissor bite. Her speech was acceptable. Gradual unilateral expansion of the mandibular alveolar bone was performed. Orthodontic tooth alignment was performed prior to surgical treatment. A tooth-borne expander was devised using a hyrax-type screw to move the inclined right alveolar bone into an upright position. Alveolar bone osteotomies were performed under general anesthesia and the expander was placed in the mandibular dental arch. After a 5-day latency period, the screw was activated for 21 days. After expansion, the width of the mandibular dental arch increased by 10 mm at the first molar region and the right molars were moved to an upright position. After a consolidation period of 7 days, simultaneous two-jaw surgery that combined Le Fort I osteotomy and intraoral vertical ramus osteotomies was performed to obtain a stable occlusion. After post-surgical orthodontic and prosthodontic treatment, her occlusion improved without deterioration of her speech. The results indicate that this technique is useful for unilateral expansion of distorted mandibular alveolar process.
