Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

22-hour tray wear time, DM assisted aligner change frequency

Group Type NO_INTERVENTION

No interventions assigned to this group

Group 2

22-hour tray wear time, VPro+ (active), DM assisted aligner change frequency

Group Type ACTIVE_COMPARATOR

Dental Monitoring assisted aligner change, 12-hour tray wear time and VPro+ are the interventions for the trial.

Intervention Type DEVICE

The current standard of care for clear aligner use as suggested by Invisalign is unclear as to how frequently aligners should be changed. We suspect that the frequency for aligner change as determined by the orthodontist using Dental Monitoring will be variable for every participant.

Vpro+ is an adjunctive therapeutic tool for clear aligner treatment. It is proposed to deliver high frequency vibrations to reduce treatment time and pain associated with clear aligners.

Align Technology suggests 22-hour wear time for clear aligner therapy. Participants in two arms of the study will be asked to wear the trays for about half the recommended wear time to assess whether night-time aligner wear will be sufficient for successful treatment.

Group 3

22-hour tray wear time, VPro+ (inactive), DM assisted aligner change frequency

Group Type SHAM_COMPARATOR

Dental Monitoring assisted aligner change, 12-hour tray wear time and VPro+ are the interventions for the trial.
