Correct answer: E — Archwire
The archwire is the active force-generating component of fixed orthodontic appliances. It is engaged into the bracket slots and exerts forces on the teeth through the brackets, producing tooth movement. Different wire types provide different force characteristics: NiTi wires provide light, continuous forces ideal for initial alignment; stainless steel wires provide high, precise forces for finishing and detailing; beta-titanium (TMA) wires provide intermediate forces. Brackets are passive attachments that transmit forces from the wire to the teeth.
