3D printing is the only way to realize digital oral medicine. At present, the commonly used 3D printing technologies in the dental industry mainly include photosensitive resin selective curing technology (SLA), selective laser melting technology (SLM), fused deposition modeling technology (FDM) and layered entity manufacturing technology (LOM). It is used in the manufacture of crowns, bridges, dental models and invisible aligners.

At this stage, 3D printers are accepted by more researchers and doctors in the medical industry. 3D printers can not only be used to create practical models such as tools, prostheses, dental implants, etc., it can even be used to 3D bioprint the human body's cells, bones and other internal biological tissues.

Nowadays, with the development of 3D printing, it is possible to customize 3D printed braces. 3D printed invisible braces is a brand-new 3D three-dimensional computer technology that tailors a series of almost imperceptible transparent braces to complete the entire correction process.

The three types of printers are similar in principle. They are all light curing, and their consumables are no different. Compared with the point-to-surface printing technology of SLA, LCD and DLP can directly print a large area, greatly improving the printing speed

At the same time, we are also developing 3D printed zirconia dentures that have good biocompatibility and are the material closest to real teeth, and avoid the drawbacks of internal cracks, wasteful verification, and high cost caused by traditional methods.

3D printing technology also has a role in the dental industry similar to 3D models in orthopaedics and tumor surgery, that is, it is used to simulate, plan the surgical process, or communicate with the patient about the surgical process. This is more convenient for dental surgery, and the possibility of medical disputes is also greatly reduced.
