We introduce an innovatively designed appliance for mandibular advancement based on Herbst’s already known appliance,
but with an interoclusal hinge. This detail makes the appliance’s use easier for patients, and gives it strength. Breakdowns are
almost non-existent. Done on the articulator, it allows a gnatological functional occlusion, above all in lateral movements, in
order to avoid any joint damage.
