This process is like tug-of-war, the teeth are retracted, just like tug-of-war, the forces are mutual, and anchor nails are needed when pulling out the retracted teeth.
The diameter is 1~2mm and the length is 6~ 12mm.
It can be fixed in bone tissue to provide absolute anchorage. When pulling out the teeth that are not arranged, you can better control the movement of the teeth, which direction to move and how much to move, all of which are arranged clearly!
Does it hurt? There are not many pain nerve endings distributed in our alveolar bone. Even after the anesthetic wears off, don't worry about the pain, just a little swelling and no bleeding. Most people in the hospital say that the pain of nailing is far less than that of tooth extraction.
