Abstract:

3D printing technology meets the needs of personalization and high precision and complex structure in orthodontics. It has received great attention in recent years and has become a research hotspot in this field. This paper briefly introduces the 3D printing technology commonly used in orthodontics, and reviews the progress of its application and research in the past years. Dental models, mini-implant surgical guides, occlusal splints, mandibular advancement devices and palatal expansion devices can be made by digital process combined with 3D printing, and unique and significant advantages are shown. With the advent of the new material, clear aligners may also be made with thermoplastic appliances by 3D printing. However, the accuracy of placing brackets in mouth using 3D printing indirect bonding trays needs to be verified and ensured by more clinical trials.
