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

Not Applicable

• Conditions: Leveling and Alignment of Teeth
• Interventions: Other: 6 weeks changing of archwire; Other: 4 weeks changing of archwire

• Registration Number: NCT04106141
• Lead Sponsor: Cairo University

Brief Summary

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.
