The term wire refers to orthodontic arch wires (other products also supply force, i.e., elastics, energy chains, coil springs, auxiliaries, extraoral appliances, etc., but they will be dealt with in other sections). Different arch wires provide different types of force, but a simplistic way to think of it is that wires have strength, springiness and memory. They will try to return to their original arch shape, and in so doing, will bring the teeth with them.
