ClinConnect Summary

This clinical trial is studying a new type of fixed retainer made from a material called cobalt-chromium, which is created using advanced 3D printing technology. The goal is to find out if this new retainer is better at keeping teeth stable after braces compared to the more traditional stainless steel retainers. The trial will look at how well these retainers help maintain tooth position, as well as how they affect overall dental health and patient satisfaction.

To be eligible for this study, participants should have recently completed orthodontic treatment with braces and have good dental health. This means they should have well-aligned teeth and practice good oral hygiene. Participants cannot have certain dental issues, such as deep bites or missing teeth, and should not have health conditions that could interfere with gum health. If you join the study, you will receive either the new cobalt-chromium retainer or the standard stainless steel retainer, and you’ll be asked to share your experiences with both types. This trial is not yet recruiting participants, but if you're interested, it could be a great opportunity to contribute to dental research.
