Expansion mandibulaire symphysaire par ostéodistraction

Thérapie combiné: EPRAC et dystraction mandibulaire symphysaire

Combined Therapy: SARPE and Mandibular Symphyseal Distraction Osteogenesis

Transverse skeletal deficiency is a common clinical problem associated with narrow basal and dentoalveolar bone. Bimaxillary transverse distraction osteogenesis for correction of OSA was first reported by Conley & Legan (2006). Mandibular symphyseal distraction osteogenesis (MSDO) evolve form tooth anchor device to bone anchor device for a better control of the distraction segment in the 3 planes of space. Its success depends on good collaboration between the orthodontist and the surgeon, and on strict patient selection. Throughout case reports, we will review the diagnosis, orthodontic and surgical treatment planning considerations to achieve clinical success.
