ABSTRACT:
This invention relates to an orthodontic appliance for correcting the positions of teeth in a jaw. Embodiments of the invention are provided with a low pull and/or a high pull and comprise adjustable spring or rubber elements for transmitting the correcting forces to the teeth. The spring or rubber elements are disposed on the outside of the mouth closely beside the teeth so that the latter are not subjected to disturbing turning and tilting torques. Turning movements of the head and movements of the jaw are compensated. A combination of a high pull and a low pull enables an optimum adjustment of the magnitude and direction of the correcting forces.
