3D printing has transformed the field of orthodontics by providing a range of benefits such as increased accuracy, efficiency, and affordability in the creation of orthodontic appliances. It is being used to create precise physical models of teeth and gums, clear aligners, custom orthodontic appliances like retainers and braces, and surgical guides. 3D printing enables customization, faster production, and lower costs compared to traditional manufacturing methods, resulting in more precise and effective treatments for patients.
