For children there are a number of different removable devices that can be used depending on the case. If the teeth are tilted or the jaw needs to be widened, we typically use active plates come (also called Schwarz’sche plates). It is composed of colored plastic brackets, and may be implemented into the small screws and springs.
If the position of the upper and lower jaw relative to one another is not correct, the bite can be normalized by a functional orthodontic appliance. These devices include the activator and Bionator.
In addition to the correction of the bite, individual tooth movement, or the widening of a jaw, we use the dual feed plate (also called S-II apparatus) and the push-back double plate (S-III apparatus) by Professor FG Sander.
