Teuscher Activator

The Teuscher Activator is a variation that eliminates the palatal acrylic for greater comfort and tongue space utilizing a large omega loop coffin spring for transverse stability. A set of lip pads extend labially from the mandibular portion of the acrylic into the vestibule to prevent the muscles in this region from restraining the forward growth of the mandible. Small loop-shaped wires known as torquing springs are positioned on the long axis of each maxillary incisor on the labial side. The springs are intended to counteract the torquing effect that the backwards force of the appliance can have on the maxillary incisors.
