Abstract
Mandibular distraction osteogenesis can take place by performing corticotomy surgery at two points on opposite sides of the mandible and at the same time attaching an expansible distraction device to the teeth of the mandible on opposite sides of the two points of the corticotomy surgery. The device is then periodically expanded until a desired mandibular length is obtained. The device includes a plurality of bands that are fitted onto the teeth of the mandible and a number of universal expansion screws that are connected to the bands for purposes of distracting the mandible. This device can be assembled with an appropriate appliance assembly tool that precisely positions and aligns the universal expansion screws relative to the bands during assembly thereof.
