With the Functional Mandibular Advancer (FMA) a newly fixed and rigid appliance for the non-compliance correction of Class II discrepancies has been developed.
Essential elements of this Herbst alternative are protrusive bars and inclined planes, which are fixed on cast splints or bands on the vestibular sides of the posterior teeth.
