An arch in dentistry is a fundamental element in orthodontics. It serves to move the teeth by forces that the bow exerts along with the brackets that are adhered to the dental surface. It has a horseshoe shape to adapt to the oral anatomy.

The elastic arcs or NiTi arcs are constructed with an alloy of metals (titanium and nickel) . They have the ability to return to their original shape despite having been deformed, that is, they have "memory", and that is why NiTi arcs effectively fulfill the function of dental alignment instrument.
