Some friends who miss the best opportunity of orthodontics always want to know which method is better for adult orthodontics? The 3D digital invisible orthodontics introduced by Quanzhou Yixing Hospital is an international cutting-edge orthodontic technology. The computer 3D technology is used to simulate the moving ways and steps of teeth, and an almost imperceptible invisible appliance is tailored. After wearing it, the teeth are moved accurately in the designed direction by applying appropriate and controllable force to them, and the invisible appliance is replaced at any time according to different stages of orthodontics, so that the teeth gradually move from the initial deformed state to the normal arrangement state, thus completing the whole orthodontic process.
