Comparison of Relapse Arch Width in Modified Vacuum Formed Retainers Covering the Palate Versus Hawley Retainer: A Prospective Randomized Control Trial

National University of Malaysia·interventional·Posted Jan 23, 2020·Updated Jan 3, 2025

In Brief

A clinical study evaluating Modified vacuum-formed retainer covering the palete for Orthodontic Retainers and Clinical Trial. Completed, enrolled 35 participants across 3 sites.

Detailed Summary

This study will focus on the relapse of arch width in two types of retention regimes, which are modified vacuum-formed retainers and Hawley type retainers in patients after fixed appliance treatment in transverse arch expansion cases. This will subsequently be of valuable information for clinicians in choosing the appropriate type of retainers after removal of their fixed appliances. This is because the modified vacuum-formed retainers will be significantly cheaper, quicker and easier to fabricate.

Interventions

Modified vacuum-formed retainer covering the paletedevice

The modified vacuum-formed retainer is made where it would cover the hard palate to the second molars. The only difference in constructing this modified VFR when compared to the normal VFR would be the outline which would be trimmed by the technician.
