Condylar resorption after bicortical screw fixation of mandibular advancement.

Purpose: This study evaluated long-term condylar resorption after mandibular advancements stabilized with bicortical screws.

Patients And Methods: One hundred mandibular deficiency patients who underwent bilateral sagittal split osteotomies (BSSO) fixed with three bicortical screws per side, and who were followed for a minimum of 1 year with complete radiographic records, were evaluated. Preoperative panoramic radiographs were traced and superimposed as a best fit over long-term panoramic radiographs.
