Scan or impressions, a bite where the design needs one, and a signed prescription. If anything on the Rx is left open, a technician calls your practice before the case is started.
Snap Fit Herbst is a trademark of Gergen's Orthodontic Lab. All trademarks are the property of their respective owners.
Same mechanism as the Sleep Herbst: bilateral telescoping arms, nothing across the midline, so the jaw still moves laterally and the patient can still speak. What changes is the arm assembly. The snap-fit hardware seats and releases without dismantling the mechanism, which makes chairside work faster and gives you fewer parts to lose.
This one is built in hard acrylic only. That is deliberate — the snap-fit assembly wants a rigid body behind it, and hard processed acrylic is what gives the appliance its working life.
