Objective: 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. Study design: 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. Results: 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. Conclusion: The presented method is a viable option for mandibular midline distraction osteogenesis. © 2006 Mosby, Inc. All rights reserved.
