Objective. The objective of this study was to decide whether use of bicortical screw fixation provides sufficient stability to dispense with intermaxillary fixation. Study design. Thirty consecutive patients who had undergone surgical setback of the mandible by means of bilateral sagittal split ramus osteotomies were studied. Group 1 (15 patients) had miniplate fixation with intermaxillary fixation for 6 weeks, and group 2 (15 patients) had bicortical screw fixation and immediate postoperative function. The 2 groups were evaluated radiographically for postsurgical changes of pogonion in the early (6 weeks) phase. Results. The results showed that there were no significant differences between the 2 groups. Overall, there was good stability in both groups. Conclusion. The use of bicortical screw fixation after sagittal split setback of the mandible provides sufficient stability to dispense with intermaxillary fixation.
