Summary

This study compares two dental devices that use small bone screws to move upper molars backward in people with a specific bite problem called Class II malocclusion. Twenty Egyptian participants will receive one of the two devices, and 3D X-rays will measure how well the teeth move. The goal is to see which device works better and causes fewer unwanted tooth movements.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Fast Back Rapid Distalizer and Modified Leaf Spring Self-Activated Expander (dental devices)
What this could lead to: If successful, this study could show which device is more effective for correcting bite problems without tooth extraction, improving orthodontic treatment options.
What could go wrong: This is a small, early-stage study with only 20 participants, so results may not apply to everyone. The devices may not work as expected or could cause discomfort.
