In an E arch, where are bands placed and what surrounds the arch?

• A. Molar bands with a heavy labial archwire around the arch
• B. Incisor brackets with a light palatal arch
• C. Premolar bands with a lingual archwire
• D. Molar bands with a wire that sits on the lingual aspect

Answer: (A)

An E arch uses molar bands as anchors, with a heavy labial archwire that runs around the outside of the teeth on the front (labial) surface. This thick wire forms a rigid framework encircling the arch, giving stable, controlled movement from the molars to the incisors. The wire sits on the labial side, not on the lingual or palatal surfaces, which is why other descriptions (incisor brackets with a palatal arch, or a lingual archwire) describe different appliances.
