ClinConnect Summary

This clinical trial is studying two different ways to improve the alignment of teeth and the appearance of the chin for people with a specific dental condition called Class II malocclusion. One approach uses a device called a bite corrector before placing braces, while the other adds small bone screws to support the bite corrector before braces are put on. The goal is to find out which method leads to better changes in the face, teeth, and bones after treatment and to understand how comfortable participants feel using these devices.

To be eligible for this trial, participants should have a certain level of Class II malocclusion, a specific dental relationship between their back teeth, and should be in the early stage of their permanent teeth coming in. They should not have any missing teeth from birth. If you join the study, you will be asked about your experiences with the devices used during treatment. This research is currently recruiting participants of all genders aged between 14 and 18 years, so it could be a good opportunity for those looking for a solution to their dental concerns.
