Abstract
Mandibular widening by symphyseal distraction osteogenesis is accomplished with the use of an appliance having first and second elongated support arms and an intervening displacement mechanism which, by rotation upon a horizontal axis, performs in the manner of a turnbuckle to force the arms apart. Lower apertures on the arms are attached to the mandibular bone, and upper apertures on the arms are attached to the teeth. Following a mid-symphyseal osteotomy and a latency period, the displacement mechanism is rotated according to a precise schedule to achieve widening of the lower jaw.
