The role of the intraosseous osteosynthesis wire in sagittal split osteotomies for mandibular advancement.
Two groups of 20 patients who were treated for mandibular hypoplasia by surgical lengthening of the mandible using the bilateral sagittal split ramus osteotomy were followed pre- and postoperatively using serial lateral cephalograms. One group of patients was treated without internal fixation and the second group, with superior border intraosseous osteosynthesis wiring. Both groups were evaluated for postoperative skeletal and occlusal changes and the results were compared. A notably greater amount of relapse was observed in the group of patients in whom no intraosseous wiring was used.
