Abstract

Orthognathic surgery is the procedure to correct dent ofacial deformity. The success of orthognathic surgery is dependent on esthetic, function and the stability of the skeleton. Surgical relapse from stability failure can result in unexpected outcome. The purpose of this study was to compare the rate of postoperative skeletal relapse in 6 months and 2 years after bilateral sagittal split ramus osteotomy in patients with skeletal class III deformity among the lower range (4˚ to < 7˚), middle range (7˚ to < 10˚) and upper range (10˚ to 12˚) of normal occlusal plane angle (Frankfort’s plane - occlusal plane 8˚±4˚). Lateral cephalometric films were evaluated at preoperative time (T0), immediate postoperative time within 2 weeks post operation (T1), 6 months postoperative time (T2) and 2 years postoperative time (T3).The proportion of the patients who had relapse versus who had no relapse between 3 groups were compared using Chi-square test and the distances of skeletal relapse were compared between groups with Kruskal Wallis and Mann Whitney U test. The results showed that the relapse was not significant between 3 groups at 6 months and 2 years after surgery (p<0.05). Conclusion, the results suggest that the difference of the occlusal plane angle; upper, middle and lower range, does not affect the skeletal relapse in this study.
