ClinConnect Summary

This clinical trial is studying how well different types of retainers keep teeth in their new positions after orthodontic treatment that involved removing the first premolars. The researchers want to find out if using a bonded lingual retainer alone is as effective as using a combination of a bonded retainer and a vacuum-formed retainer in maintaining the alignment of teeth in both the front and back of the mouth.

To participate in this trial, you need to be an adult who has completed orthodontic treatment after having your upper and lower first premolars removed and requires retainers to keep your teeth in place. Good oral hygiene is important, and your orthodontic treatment should meet certain quality standards. If you join, you will help researchers understand how well these different retention methods work, and you’ll play a part in improving orthodontic care for future patients.
