I. Internal components of the alveolar distraction device consists of three elements: (1) threaded rod, (2) transport plate and (3) stabilizing plate. The threaded rods are fabricated in three lengths. The level of the horizontal component of the osteotomy determines the length of the threaded rod required to deliver the maximum transport potential. The apical end of the threaded rod has a reduced diameter which rests into the holes of the stabilizing plate. The stabilizing plate serves to maintain the alignment of the threaded rod and therefore the direction of transport. The stabilizing plate also resists the apical movement of the threaded rod during activation.

J. Turning the hexagonal end of the threaded rod results in the vertical translation of the transport plate. The osseous transport segment moves with the attached transport plate. This movement results in a gradual widening of the horizontal component of the osteotomy. The vertical components of the osteotomy guide the movement of the transporting bone segment. Soft tissue surrounding the bone segment is expanded as the segment is elevated. The osseous ridge crest is elevated. The ridge is widened as the base of the transport segment is raised.
