Which instrument is used to bend orthodontic wires?

• A. adams crib
• B. twinblock appliance
• C. upper straight forceps
• D. adams pliers

Answer: (D)

Contouring and bending the archwire requires a precise instrument designed for that job. Adams pliers are specifically built for bending and shaping orthodontic wires near the brackets, allowing accurate angles and torque without distorting the wire elsewhere. This makes them ideal for creating the necessary bends, loops, or torque adjustments that ensure the wire seats properly in the bracket slots and guides tooth movement. The other items are not used for this purpose: an Adams crib is an appliance, not a bending tool; a twinblock appliance is a functional removable appliance; and upper straight pliers are general-purpose tools not specialized for controlled archwire bending.
