Comparative stability and outcomes of two surgical approaches for correction of class III asymmetry with lip or occlusal cant

摘要: To assess and compare the stability outcomes of two surgical approaches for patients with roll asymmetry. A total 50 adult were consecutively recruited this prospective study. Patients class III asymmetry lip or occlusal cant who underwent bimaxillary surgery grouped according to approach: asymmetric posterior impaction on both sides (API, n = 31) one side extrusion other (PIE, 19). Postsurgical between groups determined cone-beam computed tomography facial midline, lip, at 1 week (T1), least 12-month postsurgery (T2, completion orthodontic treatment). Presurgery, upper anterior significantly greater PIE group (p < 0.05). Postsurgery (T2), mandible moved upward rotated in groups. However, rotation was compared API group. Although resulted significant improvements symmetry, deviation midline remained under-corrected most patients. Patient mandibular symmetry differed correction cant. The findings study suggest that planned over-correction is a reasonable option approach sides.
