1, methods of orthodontics
Movable appliance
For beauty lovers in deciduous and tooth-changing periods, this is the best orthodontic method, which is relatively simple. It can also be corrected with a fixed appliance, and beauty lovers can take it off and wear it themselves, which is more convenient.
Bracket-free invisible appliance
Many beauty lovers have high demands on their image because of work and other reasons, so it is most appropriate to use the stentless invisible appliance, and beauty lovers can take it off by themselves. However, this method is only suitable for mild dentition crowding and individual tooth torsion.
Orthognathic surgery
Some beauty lovers have serious dentofacial deformities, such as maxillary retraction and mandibular protrusion. The general orthodontic method can not guarantee the effect because of its limited distance to move teeth. Orthognathic surgery can move teeth and bones in a large range, so the effect is better.
Functional orthodontic treatment
It is mainly used for children who are still at the peak of growth and development during or just after tooth replacement. Functional appliance can correct skeletal malocclusion. For malocclusion children with poor profile of deciduous teeth and mixed teeth, such as mandibular retrusion and anterior crossbite, functional appliance can obtain good curative effect.

Active orthodontics
It is commonly used to correct the simple malocclusion of deciduous teeth and mixed teeth, or to correct with fixed appliances. The patient can take it down by himself.
2. How long does it take for orthodontics?
Because the growth and development of adults have been basically completed, the maxillofacial suture has become bony fusion, with low plasticity, slow metabolism and reduced biological reactivity of adults. Therefore, the alveolar bone remodeling is slow, and the tooth movement is also slow, which requires a long treatment time. Therefore, adult orthodontics should be done step by step. If we insist on shortening the time, it will bring bad consequences.
Children's orthodontics generally takes about one year, and adults' orthodontics generally takes about two years.
3. Correcting the influence of teeth
1. Correcting teeth affects root.
In the process of orthodontics, the surface of root is reconstructed by absorption and proliferation. After treatment, the root gradually returns to normal with its own repair ability, but if the force is too large during the treatment, the risk of root absorption will increase.
2. Correcting teeth affects alveolar bone.
The height of alveolar bone of people who have undergone orthodontics is lower than that of people with neat teeth. This is because wearing orthodontic appliances pollutes oral hygiene, increases the probability of gingivitis and has a great impact on alveolar bone health. After orthodontic treatment, alveolar bone will no longer be absorbed. If oral hygiene is maintained, alveolar bone will gradually return to normal, otherwise it will bring harm to alveolar bone.
3. The corrected teeth will become loose.
It is normal for the tooth looseness to increase when correcting teeth. To move teeth, alveolar bone and periodontal ligament tissue need to be reconstructed. However, if the teeth are corrected to the normal position and stop moving, the periodontal ligament tissue can be reattached and become stable through their own repair ability. If it is not handled properly, it will cause permanent damage. Therefore, if the teeth are found to be too loose during the treatment, the force should be suspended and allowed to recover for a period of time to avoid further damage to the teeth.
4. Correcting teeth affects dental pulp.
In the initial stage of orthodontic treatment, there will be a temporary inflammatory reaction in the dental pulp, which is characterized by headache or other discomfort, but the symptoms will not be too serious. Therefore, everyone should pay attention to choosing a safe, hygienic and regular dental hospital when correcting their teeth.
5, the harm of improper scheme
Wrong tooth extraction easily leads to new malocclusion; If you don't grasp the right time, some teeth are arranged neatly but there is no correct occlusion relationship; If we only consider the regularity of teeth, but not the recovery of dentofacial function, it will easily lead to temporomandibular joint dysfunction, normal chewing will be affected, and teeth will feel sore when eating.
6, the harm of improper use of power
Excessive force during orthodontics may lead to gingival swelling and root resorption, and some may lead to tooth loosening or even tooth loss.
7. The harm of improper selection of electrical appliances
The bracket is unstable and easy to fall off, which will lead to the delay of correction time; Oral mucosa is deeply stimulated, which is easy to produce and aggravate oral ulcer and gingival hyperplasia; The strength can not be balanced in orthodontics, which will lead to orthodontic failure.
