1, Jaw plasticity: Jaw, especially alveolar bone, is one of the most active parts of human skeleton. The reconstruction of jaw includes two processes: proliferation and absorption, which are important physiological characteristics of jaw and the basis of orthodontic treatment. Therefore, the change of jaw during orthodontic treatment is mainly a physiological process of balance between osteoclasts and osteoblasts.

2. The compressive strength of cementum is often only absorbed by alveolar bone under the same orthodontic force, and there is no or only a small amount of cementum.

3. Stability of periodontal ligament environment. After orthodontic treatment, the width of periodontal ligament and the connection between periodontal ligament and alveolar bone and cementum can be restored to normal.
