ABSTRACT:
An orthodontic device includes an upper jaw thrust plate and a lower jaw thrust plate. These plates are connected to the teeth and are provided in the front teeth region with activating rods and slideways respectively, cooperating to effect a sagittal displacement of the jaws relative to each other. Two treatment stages are to be combined and an optimum result of the treatment within a reduced time is to be ensured. The upper or lower jaw thrust plate includes two sections, which are connected by a jackscrew mechanism, to which the activating rods are secured.
