Effect of Rigid Fixation on Orthodontic Finishing After Mandibular Bilateral Sagittal Split Setback: The Case for Miniplate Monocortical Fixation

PurposeThis report reviews the diagnosis and management of patients with Class III skeletal patterns and discusses the rationale for monocortical plate fixation after bilateral sagittal split osteotomy for surgical precision, stability, and postsurgical management of patients with setback.Materials and MethodsTwo cases with significant Class III sagittal skeletal discrepancies were identified. The cases, which required maxillary advancement and mandibular setback surgery, are presented to describe the rationale and advantages for the monocortical rigid fixation method.ConclusionsMonocortical plate fixation after bimaxillary surgery for the correction of Class III skeletal malocclusions has the advantages of excellent stability and latent postsurgical adjustability, qualities that are essential for favorable treatment outcomes.
