Claim:
1. A curved alveolar bone distractor, consisting of: an elongate curved traction rod having outer threads thereon along its entire length; a pair of anchor brackets slidably mounted adjacent the ends of the traction rod to stably support the traction rod therebetween, each of the anchor brackets having at least one anchor hole to fix the anchor bracket to a bony foundation, each of the anchor brackets being freely slidable on the traction rod, wherein each of the anchor brackets comprises an elongate, substantially L-shaped flat plate having a mounting ring extending from one end of the plate and the at least one anchor hole formed in the plate, the mounting ring coupling each of the anchor brackets to the traction rod and facilitating free sliding movements thereon, the anchor holes being adapted to receive a fastener to fix the anchor bracket to the bony foundation; a pair of endcaps capping the ends of the traction rod, the endcaps defining limits for mounting and movement of components on the traction rod; a traction bracket slidably mounted to the traction rod, the traction bracket having at least one mounting hole to fix the traction bracket onto a movable bony segment, wherein the traction bracket comprises an elongate, flat mesh plate having a mounting ring extending from one end of the mesh plate, the at least one mounting hole being formed in the mesh plate, the mounting ring coupling the traction bracket to the traction rod and facilitating free sliding movements thereon, the at least one mounting hole being adapted to receive a fastener to fix the traction bracket to the movable bony segment; and a rotating translator nut threaded to the traction rod, the translator nut being disposed between one of the anchor brackets and the traction bracket, the translator nut being pushable against a side of the traction bracket to move and separate the movable bony segment; wherein selective predetermined rotation of the translator nut in one direction pushes the traction bracket a predetermined distance to define a distraction distance for inducing new bone and tissue growth.
