Effect of Changing the Activation Frequency of the Arch Wires on the Rate of Leveling and Alignment in Moderate Crowding Cases

Cairo University22 enrolled

Overview

Leveling and alignment is the first stage in the orthodontic treatment, performed for every patient .The archwire are usually changed every 4 weeks for reactivation of the force on the teeth. However, this means that large number of appointments and archwires are required. On the other hand, there is a lack of evidence that less number of appointments with longer time intervals between the visits and less number of wires will give the same effect.
