Comparing two ways to place temporary anchorage devices for braces
Part of Mouth & dental clinical trials.
This trial tests if placing temporary anchorage devices (tiny screws used with braces) at a steady angle or in two steps works better for patients who need extra room for their teeth. It may help adults with certain bite and crowding issues.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You need braces and have had all four first premolars removed (the teeth just behind your canine teeth).
- Your upper and lower front teeth are crowded but by less than 5mm.
- Your overjet (how far your upper front teeth stick out over the lower ones) is less than 6mm.
- Your gums are healthy (BPE score 0, 1, or 2).
- You have average facial proportions (not a very long or short face).

This trial compares a new 3D-printed twin block brace to a traditional one for children with a large overbite (overjet ≥7 mm). It checks how well germs stick, how smooth the brace is, and how well it works—plus how children feel about it.
This trial compares a facemask device with upper braces to correct underbite in children ages 7–10. It aims to find which treatment works better to align the jaw and teeth.
This trial tests two different methods of using small bone anchors to move your upper back teeth further back to fix an overbite or overjet (Class II bite). It may be helpful if you've never had braces before and have good oral hygiene.
This trial compares two types of braces (aesthetic functional appliances and twin blocks) to fix ‘overbite’ where the lower jaw is too small and the upper teeth stick way out. It’s for kids/teens who are still growing and haven’t had braces before.
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 trial studies how well a treatment plan works when you start with jaw surgery and then use clear aligners for orthodontic (teeth/jaw) finishing. It may help people whose jaw growth/position problems are mainly due to the lower jaw being too far forward or the upper jaw being too far back.
