EZ-Align – Questions and Answers

What is EZ-Align®?

EZ-Align® clear aligners by DynaFlex® is a series of custom-made, clear, lightweight aligners used for the correction of misaligned teeth in teens and adults by progressively moving teeth to provide a beautiful finished smile.

How does EZ-Align® work?

The overall treatment is prescribed by the doctor to the EZ-Align® laboratory where they are fabricated. The device is manufactured using a medical grade thermoformed material known as FasTrac™. The mechanism of force application to the teeth is via intentional distortion of the material as the aligners are seated in the mouth. Each subsequent aligner in the overall progressive series is made from a mold of the patient’s teeth which reflects subtle changes in the position of the teeth from the previous aligner.

How long does EZ-Align® treatment take?

The length of treatment is dictated by the number of aligners. Typically, each aligner is worn for 7-10 days.

Refinement aligners are additional aligners used to provide continuity of the Clear Aligner Treatment. Refinement aligners are not given for relapse cases when the patient leaves the doctors treatment or loses an aligner and fails to return to the doctor. Refinement aligners are provided free for Complete Systems only and a reasonable fee is charged for all other systems.
