Which appliance provides significant tooth movement and skeletal effects?

• A. Invisalign
• B. E arch
• C. Herbst
• D. Essix

Answer: (C)

In growing patients, fixed functional appliances that posture the jaw can influence both tooth positions and the size/shape of the jaws themselves. The Herbst appliance does this strongly: it continuously holds the mandible forward, which stimulates skeletal changes such as mandibular growth and condylar remodeling, while also producing dental movements like tooth tipping and alignment. Clear aligners like Invisalign or Essix mainly move teeth and adjust occlusion without actively triggering jaw growth, so their skeletal impact is minimal. The E-arch can produce some skeletal effects, but the Herbst is the classic choice when the goal is substantial changes in both the teeth and the jaw structure.
