Abstract
Aim: The purpose of this study was to evaluate the stability of bimaxillary surgery with rigid fixation for correction of class III malocclusion using lateral cephalometric radiographs in U.A.E population.
Materials and methods: The sample consisted of lateral cephalometric radiographs of 13 non growing patients, 5 males and 8 females, presenting skeletal class III malocclusion of U.A.E ethnicity. Patients were selected using certain inclusion and exclusion criteria. Cephalometric radiographs were taken at 2 time intervals, T1 which is soon after surgery and T2 which is at least 1 year follow up. 19 variables were used (8 skeletal and 11 dental components).
Results: There was statistically significant difference in U1-NA degrees, overjet, SNB and FMA from T1 to T2. U1 to NA (degrees) increased from T1 to T2 from 18.1 degrees to 21.2 degrees. Overjet decreased from 3.8 at T1 to 3.1 at T2. SNB increased from 82.1 degrees at T1 to 82.7 degrees at T2. FMA increased from 28.3 at T1 to 28.9 at T2. Even though there was a statistical difference from T1 to T2 for SNB, overjet and FMA, clinically this difference was very small.
Conclusion: Within the confines and limitations of the present study, it can be concluded that bimaxillary surgery for the correction of class III malocclusion is relatively stable.
