title: Mandibular symphyseal distraction osteogenesis: diagnosis and treatment planning considerations.
abstract: Treatment planning decisions in the transverse dimension have historically been based on the presenting mandibular arch width and form. Distraction osteogenesis (DO), originally developed by Russian orthopedic surgeon Ilizarov, has produced significant results in limb lengthening. Mandibular symphyseal DO was introduced by Guerrero, providing a new paradigm for patients whose treatment alternatives and results were previously limited. Orthodontic and surgical techniques and principles will be shown using completed and current cases.
