[An orthodontic apparatus for treating distal occlusion of the dental arches].

To cut down the period of orthodontic treatment, achieve better effects, and normalize the function of the tongue, an orthodontic device is suggested, which consists of a plate for the maxilla with a palatine clasp and an active wire element of a symmetrical arch-shaped design, welded in the plate, which affects the lower dentition during dentition occlusion.
