Invisible braces was first developed in the United States in recent years. This technique is very different from previous orthodontics. First, doctors use computers to reconstruct three positions of patients' teeth, analyze which teeth need to be corrected, and then use computers to adjust the positions of teeth. For example, if a tooth needs to be moved by 2 mm, it can be done step by step with 10, and each step is moved by 0.2 mm, and the image after each step is output to make braces according to the figure. Patients wear braces for correction, which are plastic braces, the thickness of which is about a few tenths of a millimeter. They are very powerful to teeth, and it is not easy for others to see that they have done orthodontics.

However, this method is not suitable for everyone. At present, it is mainly aimed at patients with less serious tooth dislocation. Besides being beautiful, the biggest advantage of this method is that patients don't have to wear braces when eating. They can take it off when eating, clean their teeth after eating and wear it again, which has little effect on oral hygiene. After a while, I went to the hospital for a follow-up visit. After evaluation, the goal of the first step has been achieved, and then proceed to the second step.

There is also a completely invisible braces, which is a metal appliance, but it is worn on the inside of the teeth. According to the stress points and stress points of teeth, orthodontic treatment is carried out from stainless steel brackets, steel wires and other aspects. There seems to be no appliance because it sticks to the inside of the tooth. However, because it is located inside the teeth, the operation is very difficult, so the treatment cost is much more expensive than the general one. This method is suitable for all kinds of patients with tooth dislocation.
