The Use of 0.018" Special Plus Wire For Fabricating "Z-Springs" For Correction of Anterior Cross Bites.

Double helical cantilever springs of “Z-springs” are frequently used to correct one or two teeth anterior cross bites. Different wire sizes of round stainless steel wires have been suggested by various authors for the fabrication of these springs. The 0.018” Special Plus Australian wire is an excellent choice for the fabrication of the “Z-spring” because of it’s hardness and resilience.
