Herbst Appliance
Pronunciation: HAIRBST uh-PLY-uns
A fixed functional appliance that postures the mandible forward to stimulate condylar growth and correct Class II skeletal discrepancies.
Full Definition
The Herbst appliance is a fixed intraoral device consisting of bilateral telescoping metal arms that connect the maxillary and mandibular arches, holding the lower jaw in an advanced position. First described by Emil Herbst in 1905, it was reintroduced in the 1970s and is widely used in growing patients with retrognathic mandibles. Unlike removable functional appliances, the Herbst is bonded or banded to the teeth, ensuring continuous orthopedic force. Editors should capitalize 'Herbst' as an eponymous appliance name and always pair it with 'appliance' on first reference in clinical documents.
Usage
Usage note: 'Herbst' must always be capitalized as it is an eponym. Do not write 'herbst appliance' in lowercase.
