About

This study will examine shortened treatment wear time for patients with mixed dentition using sequential dental aligners. Using the existing AirFlex aligner design that patients with permanent dentition use, it may be possible to reduce the wear time and still provide dental realignment in an adequate treatment period for patients with mixed dentition. The Airflex aligner will be tested for a 9-12-hour patient wear time.

Full description

The primary intervention is the change in active wear time. In current practice, sequential aligners are prescribed to be worn approximately 20 to 22 hours per day. In this study, the prescribed wear time will be reduced to 9 - 12 hours per day.

This study is intended to demonstrate effectiveness of AirFlex aligners, which have a reduced wear time compared to traditional aligners, in mixed dentition subjects. The study will be conducted using AirFlex aligners, which are currently cleared for treatment of patients with permanent dentition.
