Condylar Head Remodeling compensating for Condylar Head Displacement by Orthognathic Surgery

The purpose of this study was to evaluate the association between kind of condylar displacement due to orthognathic surgery and the subsequent adaptive condylar head remodeling.The sample in this retrospective cohort study consisted of 30 patients (12 female and 18 male; mean age 22.7y) with skeletal Class III malocclusion who underwent bilateral sagittal split ramus osteotomy (SSRO). Three-dimensional superimpositions of cone-beam computed tomography (CBCT) scan derived images from immediately after and 6 months after surgery were to reveal the type of remodeling, while images from before and immediately after surgery were to identify the subsequent type of condylar displacement.
