Application progress of three-dimensional printing technology in orthodontics

Abstract

Three-dimensional (3D) printing technology, known as additive manufacturing, is an advanced technology that rapidly developed in the late 20th century. In the medical field, 3D printing technology has achieved breakthrough progress in medical model manufacturing, implant placement, and prosthodontics and orthodontics. In this paper, the application of 3D printing technology from the perspective of orthodontics, such as dental models, clear aligners, orthodontic brackets, transfer trays, and removable appliances, is reviewed. The application of 3D printing technology is increasingly used in the orthodontic field due to its advantages of high accuracy, high efficiency, simple operation and personalization, and an increasing number of economic applications in the medical field are worth the wait.
