Abstract
A maxillofacial anchoring and distraction system having an internally threaded anchoring or distraction fixture () and a selected length jack screw () for placement in an osteotomy. To minimize required bone height, a cut-away bone screw () or a solid mesh tip () is provided for insertion in bone in a direction generally perpendicular to the longitudinal axes of the anchoring and jack screws. A flat surface portion () serves as a reaction surface for the distal end of the jack screw. In a second embodiment a sealing screw () is used with distraction fixture () modified to include a sealing surface. After completion of distraction the sealing screw is used to seal off the distraction fixture for conversion into an implant suitable for receiving conventional prosthetic components.
