title: The Tweed-Merrifield philosophy.
abstract: Charles Tweed's concepts have been simplified, enhanced, and expanded by Levern Merrifield. Merrifield's ideas have augmented Tweed's to give orthodontics the Tweed-Merrifield philosophy. Adherence to the philosophy allows the orthodontic specialist to define objectives for the face, the skeletal pattern, and the teeth, and to diagnose and treat a malocclusion to efficiently reach these predetermined objectives.
