title: A functional appliance system for the correction of class II relationships.
abstract: A technique is described for the correction of Class II malocclusion involving a functional appliance and consisting of three phases. 1. Adjustment of posterior arch width and dental alignment, using semi-rapid maxillary expansion by means of an upper removable appliance, to co-ordinate the anticipated positions for the arches. 2. Correction of the Class II dental relationships using a modification of the twin-block functional appliance. 3. Retention, using an upper removable appliance with a very steep anterior bite plane. The technique is illustrated by a case report.
