Herbst appliances provide significant what effects?

• A. Cosmetic changes only
• B. Tooth movement and skeletal effects
• C. No significant effects
• D. Skeletal changes only

Answer: (B)

Herbst appliances work by holding the mandible forward, which can induce both skeletal changes and dental movements. In growing patients, the forward posture can stimulate some remodeling and growth of the mandible, improving jaw relationship beyond what happens from tooth movement alone. At the same time, the appliance causes tooth movements to adapt to the new jaw position, such as tipping or repositioning teeth and changing molar angles to improve occlusion. So the overall effect is a combination of skeletal changes and tooth movement, not just cosmetic change or only one type of change.
