[Control of vertical dimension in the treatment of Class II malocclusion using a combined activator and extraoral traction appliance].

Abstract

The aim of this work is the study of effects on vertical dimension of a functional appliance: combination of headgear and activator. We have pointed out in this study: a good control of occlusal and palatal plans; vertical stability of ANS; no change of facial axis; intrusion of maxilla incisors; correction of anterior deep-bite. We concluded that this combination headgear activator, in addition to the sagittal correction of Class II, permitted a good control of vertical skeletal and dental dimensions.
