3D printing a straighter smile Medical
No longer is it necessary to be saddled with bracket and wire braces for consecutive years in order to achieve a straighter smile: people around the world can correct their teeth alignment using customized clear aligners, which are not only much more discrete, but can be removed without professional intervention. The growing adoption of clear aligners—the market was reportedly worth over $2 billion in 2019—is due in no small part to 3D printing, a technology which has enabled orthodontic labs and specialist companies to achieve customization on a mass scale.
