Stability after braces with premolar removal and special retainers
Part of Mouth & dental clinical trials.
This study tests whether using a special type of retainer (bonded on the tongue side and the roof of the mouth) helps keep teeth stable after braces for people who had their upper and lower first premolars removed. If you're finishing orthodontic treatment and need a retainer, this study may apply to you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be an adult (18 or older).
- Your orthodontic treatment included removing both upper and lower first premolars (the teeth next to your eyeteeth).
- You should be at the final stage of braces or have just finished, and you need a permanent bonded retainer on the front of your lower teeth and roof of your mouth.
- You must have good oral hygiene (clean teeth, no gum problems).
- Your pre-treatment records (like X-rays and teeth models) must be available.
- Your teeth must be well aligned and finished properly as judged by your orthodontist.

This trial studies the types of bacteria found in dental plaque from people who have orthodontic retainers after braces. It aims to understand how retainers affect oral bacteria.
This study compares three types of retainers (a bonded wire, a clear plastic tray, and a combination of both) to see which one holds your teeth in place best after braces. It is for adults who have finished non-extraction orthodontic treatment and are generally healthy with good oral hygiene.
This study compares two types of space maintainers (prefabricated versus custom-made) for children who need a lower baby molar removed. The goal is to see which type lasts longer and works better to keep space for the permanent tooth.
This study compares how different face types maintain their bite after orthodontic braces are removed. Researchers will use 3D imaging to track whether teeth stay in their corrected positions during the retention phase (when you wear retainers).
This study tests a custom-made metal retainer that fits behind your lower front teeth. The retainer is designed using a computer and made from a special dental alloy (cobalt-chromium). It aims to keep your teeth straight after braces.
This study compares two types of retainers (a wire that keeps teeth in place) after braces are removed: one that is directly bonded to the teeth and one that is made indirectly. It looks at which type keeps gums healthy, lasts longer, and how likely it is to break.
