New 3D-Printed braces could stop tooth decay while straightening teeth
NCT ID NCT07603427
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This laboratory study aims to create a better type of clear orthodontic aligner (like Invisalign) by adding ingredients that fight bacteria and help repair tooth enamel. Researchers will test these new materials on extracted human teeth in a lab, measuring how well they kill germs and release minerals to strengthen teeth. No human participants are involved, and the goal is to see if these smart aligners can prevent the tooth damage sometimes caused by wearing braces.
