Which instrument is used to form and bend wires?

• A. Scaler
• B. Bird-Beak pliers
• C. End nippers
• D. Distal cutting pliers

Answer: (B)

Forming and bending wires requires a tool with a beak-like jaw that can shape flexible orthodontic wire without kinking it. Bird-beak pliers are designed for this exact task. Their two curved, tapered beaks let you create precise bends, loops, and contours in archwires and ligature wires, positioning the wire exactly where it needs to fit around brackets and along the dental arch. The design allows controlled deformation of the wire so movements can be planned and implemented accurately.

Scalers are for removing calculus from tooth surfaces, not shaping wires. End nippers trim or remove wire ends, but don’t provide the controlled bending needed for forming arches or loops. Distal cutting pliers are used to cut wire ends, especially at the distal ends of wires, rather than to bend or form them.
