The concept of the clear aligner is similar to traditional braces in that a force is placed on a tooth in a controlled manner and the body responds by initiating tooth movement. The only difference is that the force is applied through the clear tray.

Clear aligners work best for mild cases. Usually, two - three sets of 3 aligners are required as the gentle movement takes place incrementally. Each aligner is normally worn full time for one week.

Like the other forms of Social 6 treatment, it is always necessary to hold the teeth in their corrected position with a combination of a fixed retainer and removable retainer retainer.
