[Improvement of the clinical application of the elastic open activator of Klamt].

Abstract

Changes are proposed in the technology and construction of the elastic open activator of Clamt aiming at its improved clinical application. In order not to stand in the way of the cutting of the permanent lateral teeth as well as of their correct arrangement after their cutting, the vestibular bars are proposed to come out lingually in the space between the upper and lower teeth at the approximate level of the expected occlusion plane after the cutting of the teeth. In case of retrusion of the frontal teeth, the vestibular bars are made compensatory omega-like bends which allow an easy and fast correction of the frontal part of the bar with no change vertically. Similar omega-like compensatory bends are used also for the correction of the proposed wire elements that support the pelota for the stimulation of the development of the apical base in the frontal region.
