  • Title: Active vertical control with skeletal anchorage for optimizing facial profile in a severe Class II high-angle protrusion case.
    Author: Liaw J, Wang SH, Chen HK, Chen YJ.
    Journal: Angle Orthod; 2024 Aug 22; ():. PubMed ID: 39195346.
    Abstract:
    This case report describes the nonsurgical management of a patient with a Class II skeletal pattern, retrognathic mandible, steep mandibular angle, maxillary vertical excess, and lip incompetence. The treatment approach involved orthodontic mechanics supported with skeletal anchorage to achieve maximal intrusion and retraction of the dentition. A novel elastic hanging rack appliance, supported by midpalatal miniscrews, was used. A maximal anchorage setup for active vertical control on both arches was illustrated. Significant improvement in the facial profile was achieved with optimal occlusion. Cephalometric analysis revealed successful incisor retraction and intrusion, as well as a forward rotation of the mandible. The treatment outcome illustrates the impact of active vertical control on orthodontic camouflage treatment for severe protrusion.
