Scheu Telescopic Herbst Hardware - IST Positioning Support Arm
This unique hardware allows the clinician to advance the mandible in .25mm increments (up to 8mm) by making one full turn of the protrusion nut incorporated into the hardware. Also, an end stop in the guiding sleeve prevents the rod and tube from disengaging, reducing the problems associated with loose intraoral hardware. Important: Herbst Telescopic Hardware should be used for snoring and sleep apnea appliances only.
