Comparing two ways to move upper teeth backward with tiny screws
Part of Mouth & dental clinical trials.
This trial compares two methods (sliding jigs vs retraction hooks) to move your upper teeth backward using small screws placed in your jawbone. It may help if you have a mild overbite or crowded upper teeth and want to avoid removing teeth.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be an adult over 14 years old with all your permanent teeth (except wisdom teeth) fully grown in.
- Your upper back teeth should be positioned too far forward compared to your lower back teeth (Class II bite).
- You should have slight to moderate crowding in your upper teeth (less than 5 mm) and your upper teeth stick out.
- You should not have any conditions of the face or skull (like cleft palate) and no gum disease.
- You must not need any teeth removed (except wisdom teeth), and you should not have had braces before.
- You should not have a vertical growth pattern (excessive open bite) or any side-to-side jaw issues.

This study compares two ways to move the upper back molars backward to fix an overbite where the upper teeth stick out too far. One method uses clear aligners, the other uses tiny temporary screws in the jawbone.
This study tests a way to move your upper teeth and jaw backward using tiny screws placed in your cheekbone area, which may help correct an overbite without needing to remove teeth.
This trial compares two methods for moving your upper canine teeth back after having upper premolars removed, as part of braces treatment. It aims to find which method works better for people with crowded teeth.
This study tests two ways of placing small temporary anchors (mini implants) in the jaw to help pull upper front teeth back into a better position. It is for patients who have finished growing and have a Class II overbite, to see which anchor location works best.
This study compares two sizes of tiny screws (called miniscrews) that are sometimes used with braces to help move teeth. The screws are placed in the upper jaw to help correct an overbite where the top teeth stick out too far. The study looks at how well the screws work, how stable they are, and how they feel to patients.
This study compares two types of braces (functional appliances) used to fix an overbite caused by a lower jaw that is too far back. It looks at which brace works better for growing teenagers. If your child needs jaw alignment, this trial could help them get treatment.
