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.

Conditions

  • Orthodontic Retainers
  • Clinical Trial

Interventions

DEVICE

Modified vacuum-formed retainer covering the palete

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.
