ABSTRACT:
A bone distraction device fixed by screws to a sectioned bone to facilitate multidirectional repositioning of the jaw bone. The expansion device is expandable to cause incremental expansion in the bone for lengthening or widening thereof. Support wires extending from the device can be clipped to desired lengths to accommodate the particular orientation of the device with respect to the bone. Forked or split anchor ends are then attachable to the wire arms and crimped or otherwise secured thereto. The anchor ends engage with respective bone screws so that when the expansion device is activated, the bone is forced apart.
