Background: The aim was to evaluate the long-term hard and soft tissue changes following mandibular advancement and setback surgeries. Materials and Methods: A total of 16 subjects each were selected who underwent bilateral sagittal split osteotomy mandibular advancement and mandibular setback groups. Pre-surgical (T1), immediate post-surgical (T2) and long-term post-surgical (T3) cephalograms were compared for hard and soft tissue changes. After cephalometric measurements, the quantity of changes between T1-T2 and T1-T3 were determined for each patient. The mean difference between T1-T2 and T1-T3 was compared with assess the long-term changes and stability. Results: In mandibular advancement the mean difference between immediate post-surgical and long term post-surgical is 7%, which accounts for a relapse of 7%. In mandibular setback, the mean difference between immediate post-surgical and long-term postsurgical is 29%, which accounts for a relapse of 29%. Conclusion: Mandibular advancement remained stable over the long period when compared to mandibular setback. [ABSTRACT FROM AUTHOR] |
