01 Functional Regulator according to Fraenkel

The Functional Regulator according to Fraenkel is a device for the orofacial muscles to establish new neuromuscular performance patterns. The projecting vestibular shields and lip pads of the functional regulator may help to overcome an inadequate development of the inferior (FR1/FR2) or superior (FR3) portion of the oral functioning space. This is the requirement for a physiological size development of the jaws as well as their correct position relation.
