Description
Summary:Mandibular midline distraction osteogenesis represents a new option for creation of intra-arch space in the mandibular arch. The aim of this paper is to introduce a simple device (hyrax expander) and method for mandibular midline distraction. The sample consisted of 24 patients (mean age: 18.07 years) treated with mandibular midline distraction. Hyrax expanders were used as symphyseal distractors, and distraction procedure was carried out with a rate of 1 mm and rhythm of twice daily. Mandibular midline distraction was completed successfully in all patients and the distraction amount was 7.01 mm. No major complication other than mild mucosal irritation and gingival recession was observed. The presented method is a viable option for mandibular midline distraction osteogenesis.
