Clinical Trial to Assess the Efficacy of Reducing the Aligners' Wear Protocol on the Predictability of Orthodontic Tooth Movement
Study Details
Study Description
Brief Summary
The hypothesis of this project is that replacing the current 7-day wear protocol with a 3-day wear protocol, while integrating less tooth movement per aligner (reduce the amount of activation per aligner) may produce more consistent and continues orthodontic forces, therefore, increase the predictability, accuracy and outcomes achieved for various types of tooth movements and enhance the rate of tooth movement with the Invisalign system

Outcome Measures
Primary Outcome Measures
- predictability of the different orthodontic tooth achieved in each of the studies groups movements achieved at the end of treatment in each of the studied groups (3-day wear vs 7-day wear). [14 months]
assess the influence of reducing the wear scheduled for Invisalign clear aligners, from 7- day wear to 3-day wear, on the predictability and accuracy of different orthodontic tooth movements by comparing the simulated predicted final outcomes to those achieved at the end of treatment between the two wear protocols.
- rate of tooth movement for the lower anterior teeth as detected by the consecutive scans captured by the scan box (Dental Monitoring®) in the first 8 weeks of treatment [2 months]
compare and quantify the magnitude and rate of orthodontic tooth movement between the suggested (3-day) and conventional (7-day) wear protocols for the Invisalign® system using the Dental Monitoring superimposed scans and the data collected from their online platform in the first 8 weeks after Invisalign delivery.
Secondary Outcome Measures
- duration of treatment [14 months]
the total time needed to complete treatment
- number of refinements and visits needed for each wear protocol. [14 months]
the number of additional mid adjustment treatment scans needed for each included subject during the clinical trial duration
- Occlusal outcomes [14 months]
The Peer Assessment rate and/or ABO grading system will be used to measure the final occlusal outcomes achieved in both groups for them to be compared.
