Incisor torque by means of a modified Teuscher activator

It is generally accepted that in the treatment of Class II, 1 malocclusion classical activators may tip the upper incisors considerably. In comparison, in the cases described, an even better torque control was obtained. It has been our clinical experience that with the modified Teuscher activator it is possible to control upper incisor inclination and in some cases it is even possible to induce active palatal root torque. The appliance is relatively comfortable with good vertical retention even without headgear.
