herbst appliance – operating principle

operating principle

In class II patients herbst appliance moves mandibula from the first day of treatment into a incisal edge to edge position or so called super class I. At any time of treatment it is possible for the patient to open mouth, do chewing procedures and speak as he likes to.

As mandible is in this foward position posterior molars are in a open bite but in the next weeks of treatment this open bite will close again and stabilize the class I position.
