Orthodontic principle: In the process of orthodontics, tooth movement can be divided into two stages, including biomechanical stage and biological stage. Biomechanical stage means that the appliance produces various corrective forces on the teeth and transmits them to the periodontal ligament through the teeth. Biological stage refers to the histological changes of periodontal ligament and alveolar bone caused by stress, alveolar bone reconstruction, which leads to tooth movement. Different orthodontic forces act on teeth, and the types of tooth movement are also different. The types of tooth movement are usually divided into inclined movement, whole movement, sudden pressure movement, root control movement and rotation movement. Biomechanical analysis is mainly due to the different positions of impedance center and rotation center, which leads to different types of tooth movement. In addition to simple tooth movement, modern orthodontics in a broad sense also includes treatments to adjust the position and size of craniofacial jaw, such as the treatment to promote mandibular growth in adolescence and the treatment to improve adult craniofacial skeletal deformity through orthodontic-orthognathic treatment.

clinical symptoms
When I first started wearing the appliance and a week after each follow-up, I felt toothache, unable to chew or even dare to touch them. Actually, this is a normal phenomenon. Generally, the pain will gradually disappear after a few days, and there is no need for orthodontists to worry. This is caused by the strength of the appliance. Regular orthodontic treatment step by step will not cause damage to teeth and periodontal tissue.
Principles of treatment
There are many methods of orthodontics, such as resin veneer, porcelain veneer, porcelain teeth, orthodontics and so on. According to the actual situation of individual teeth and the type of tooth deformity, the treatment method should be selected, and then combined with individual requirements. Each method has its own advantages and disadvantages, and we need to communicate with the doctor directly to determine the plan during the examination.
At present, the regular top three hospitals have corresponding departments, and the prices are also open and transparent. Because different revision schemes are involved, the price will be different, so specific consultation can be made when determining the revision scheme.
