ClinConnect Summary

This clinical trial is studying the effects of two types of orthodontic devices—modified fixed twin blocks and removable twin blocks—on young patients who have a specific dental condition called skeletal Class 2 malocclusion. This condition means that the upper jaw is positioned too far forward compared to the lower jaw, which can lead to bite problems. The trial is currently recruiting female patients aged between 3 and 5 years who show signs of growth and have a noticeable overbite (where the upper teeth significantly overlap the lower teeth).

If you or your child are eligible to participate, you can expect to receive one of the two treatments and be monitored to see how well each option works in correcting the malocclusion. It's important to note that patients who have already had certain types of dental treatment, are older than 15 years, or have specific dental conditions are not eligible for this study. This research could help improve orthodontic treatments for children with similar conditions in the future.
