Summary

This study compares custom-made and ready-made Carriere motion appliances for correcting Class II malocclusion (overbite) in 24 teenagers aged 12-15. The goal is to see which device achieves a proper bite faster and with better patient satisfaction. Participants will be randomly assigned to one of the two braces, and treatment duration, dental changes, and comfort will be tracked over about 6 months.

What this could mean

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

Active substance
Carriere motion appliance (custom-made or ready-made)
What this could lead to
If successful, this could show that custom-made braces work faster or better than standard ones for correcting overbites in teenagers.
What could go wrong
This is a small, early-stage trial with only 24 participants, so results may not apply to everyone. The devices are for dental alignment, not a cure for the underlying jaw condition.
