Abstract


For the purpose of studying postsurgical stability of mandibular prognathism, 18 patients (8 men and 10 women) were selected who underwent sagittal split ramus osteotomy and lateral cephalograms taken preoperatively, immediate postoperatively,
and
over
6-month follow-up were traced and anlaysed.
@ES The following results were obtained.
@EN 1. Average magnitude of setback was 11.0mm, and aberage relapse was 3.09mm, so the rate of relatpse was 27%.
2. Magnitude of mandibular setback contributed to relapse.
3. The patients of less than 10mm setback showed average 10% of relapse rate, and it was of little clinical significance.
4. Proper detachment of pterygomasseteric sling, prevention of clockwisc rotation of proximal segment and righd fixation are recommended for the better postoperative stability.
