Herbst Appliance
The Herbst Appliance is a fixed functional orthodontic device designed to correct mandibular retrognathia (retruded lower jaw) or Class II malocclusion. By applying consistent mild force to advance the lower jaw, it promotes mandibular growth and development while improving the alignment of the upper and lower arches. The Herbst Appliance is highly effective and is commonly used in children and adolescents during their growth phase.
