ClinConnect Summary

This clinical trial is studying two types of fixed retainers used to keep teeth in place after orthodontic treatment: a traditional metal retainer and a new 3D printed metal retainer. The goal is to compare how well these two types of retainers hold up over time, especially regarding any failures in their bond to the teeth. Researchers want to find out if one type is better than the other, as there are mixed opinions about how often traditional metal retainers fail.

To participate in this trial, you should have recently completed orthodontic treatment and have a healthy set of teeth, including four permanent lower front teeth and two lower canine teeth. You should also have good oral hygiene and not have any current dental issues, like cavities or gum disease. If you join the study, you can expect to have regular check-ups to monitor how well your assigned retainer is working. This trial is currently looking for participants of all genders between the ages of 18 and 78.
