简要总结

This study aims to help improve individualization and optimization of clear aligner therapy through the use of new technologies in orthodontics. The study will compare 12-hour and 22-hour tray wear time and evaluate the adjunctive use of Vpro+. The study clinicians will use Dental Monitoring to monitor study participants throughout the trial and will use the Dental Monitoring system to instruct patients to continue or stay on their clear aligners. The outcome of the study will be the time it takes to complete 10 trays.
