Use of the segmented LeFort I osteotomy to correct severe extrusion of maxillary posterior teeth or tuberosities.
The segmented LeFort I osteotomy technique is presented as a surgical alternative for the correction of severe posterior maxillary vertical excess prior to prosthodontic procedures. It allows the extruded maxillary dento-osseous segment to be retained and a normal plane of occlusion to be reestablished. The superior visibility, accessibility, and versatility afforded by the segmented LeFort I osteotomy technique make it particularly suited to the correction of severe posterior maxillary excess.
