Comparing small screws for braces in the upper jaw
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 13 and 50 years old
- You do not smoke
- You have good oral hygiene
- You have a specific type of overbite where the upper teeth and jaw stick out (called Class II Division 1 malocclusion)
- You need extra support (anchorage) to move your teeth, and your overjet (distance between top and bottom front teeth) is more than 6mm
- You are having your upper first premolars (the teeth next to the canines) removed as part of your treatment

This study tests two types of orthodontic wires to see which one more effectively moves your upper canine teeth backward when you're already wearing fixed braces. The goal is to find the best method for straightening your bite with minimal side effects.
This study compares two ways of placing tiny orthodontic anchors (called temporary anchorage devices, or TADs) in the jaw to help braces move teeth effectively. It tests if one insertion method is more stable and comfortable than the other, which may improve treatment outcomes.
This study tests how well tiny screws placed in your upper cheek area work to support braces and move teeth into the right position. It is for adults aged 19 to 35 who need fixed braces on their upper teeth and have not had braces before.
This trial tests whether special coated mini-screws placed in the jaw can help move teeth and resist infection. It's for teens and young adults getting premolars removed as part of braces treatment.
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.
This trial tests special small screws coated with nano-material to help move upper front teeth back into place during braces treatment. The screws act as anchors to make tooth movement more effective for patients with protruding upper front teeth.
