Summary

This study looked at 150 people with crooked teeth who got small temporary screws placed in the roof of their mouth to help straighten their teeth. Researchers checked how well the treatment worked, how it affected quality of life, and if there were any problems. The goal was to see if these screws are a safe and effective tool for orthodontic care.
