Clear Comfort Aligners are normally worn for 1 week each. It has proven helpful with non-compliant patients or challenging tooth movements to have the patient wear aligners longer than is instructed on the aligner label.
Additional wear time is at the provider’s discretion, but 1-2 week extended wear is recommended. This extended wear can be specific to periods of treatment, or span the entire length of treatment depending on the circumstances.
After 3-5 days of 22 hour daily wear the movement of the aligner has generally fully expressed, however, extended wear time of the aligner will provide retention and allow the periodontal ligaments to catch up.
