3D printing technology has greatly helped the field of orthodontics become more modern. One of the most popular forms of orthodontic treatment—Invisalign—relies on it to create the aligners used in the system. Other appliances that can be created using 3D printing are retainers, tooth whitening trays, and mouthguards.
When 3D printing is used to create an appliance, digital scanning technology creates the blueprint. Digital scanners take thousands of images of the dental anatomy and then the software assembles them into a 3D model. From there, the appliances are designed to fit the anatomy as captured in the scan. The 3D printer then crafts the appliance.
Patients benefit from the use of 3D printing because it allows for custom made appliances that deliver better results. With the use of 3D printing, it is possible to achieve the perfect smile in less time.
