Abstract
The Tweed-Merrifield directional force technique is a useful treatment approach for a patient with a Class II malocclusion with dentoalveolar protrusion. The purpose of this case report was to present the diagnosis and treatment descriptions of a patient with an Angle Class II malocclusion complicated by tooth losses, severe dentoalveolar protrusion, and skeletal discrepancy. Treatment involved extraction of the maxillary first premolars, high-pull headgear to enhance anchorage, and high-pull J-hook headgear to retract and intrude the maxillary anterior segments. A successful outcome was achieved with traditional orthodontic treatment in this borderline surgical case.
