Abstract
The objective of this study was to determine skeletal stability of bilateral sagittal split osteotomy with counterclockwise rotation in the correction of skeletal class III openbite at the Oral and Maxillofacial Surgery Department of Chonburi hospital. This is a 7-year retrospective study of 28 patients. We measured Sn-GoGn, FMA, overbite, and overjet cephalometrically at 3 points for each patient: preoperative, immediate postoperative, and postoperative 1 year. The differences in SN-GoGn, FMA, and overbite between preoperative and immediate postoperative had no statistical significance, but the overjets at preoperative and immediate postoperative were statistically different. The differences in SN-GoGn, FMA, and overjet between immediate postoperative and preoperative 1 year showed no statistical significance, but the overbites at immediate postoperative and preoperative 1 year were statistically different. The skeletal stability of bilateral sagittal split osteotomy with counterclockwise rotation in the correction of skeletal class III openbite was 82.2%. The conclusion of this study was the alternative treatment of skeletal class III with mild openbite was bilateral sagittal split osteotomy with counterclockwise rotation.
