Comparing two types of clear aligners for teeth straightening
Part of Mouth & dental, Pain clinical trials.
This study tests two different ways of making clear aligners (custom plastic trays that move your teeth). Researchers want to see if 3D-printed aligners work as well as traditional heat-formed ones for mild crowding or spacing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be between 15 and 30 years old with all permanent adult teeth (except wisdom teeth)
- Have mild crowding or spacing (gaps or overlap less than 5 mm) and slight tooth rotation (less than 30 degrees)
- Have healthy gums and teeth with no cavities, gum disease, or previous tooth injuries
- Have good daily tooth-brushing habits
- Not be pregnant, a smoker, or have medical conditions that affect bone healing
- Have never had braces or teeth extracted before

This study compares two ways to straighten teeth: self-ligating braces (a type of bracket) and clear aligners (like Invisalign). It looks at how well each works to fix moderate crowding.
This study compares two ways of making clear plastic aligners to straighten teeth. It looks at whether directly 3D-printed aligners work better than ones made by pressing a plastic sheet over a 3D model. This could be for people with mild to moderate teeth alignment issues.
This study uses donated teeth (removed for other reasons) to test new 3D-printed clear aligners that may fight bacteria and help rebuild tooth enamel. The goal is to make orthodontic treatment safer and healthier for teeth.
This study compares two types of clear aligners (3D printed vs. thermoformed) to see how they affect your jaw bone. If your teeth are mildly crooked and you're a non-smoker with healthy gums, you might be a good fit.
This study compares 3D-printed clear aligners with traditional thermoformed aligners for patients with mild to moderate crowding. If you qualify, you may receive one of these aligner types to straighten your teeth.
This study compares two types of clear aligners (dental trays that straighten teeth) to see how well they fit. It may help improve future aligner design.
