Details and patient eligibility

About

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.
