1. Reasons for rebound after correction
(1) without fixer
Generally speaking, the corrected teeth are not stable in the new position, so it is necessary to keep the new tooth position with the help of the retainer and wait for the reconstruction of alveolar bone. If some people don't wear retainers or wear retainers incorrectly, the corrected teeth may still move back to their original positions and rebound and relapse.
(2) unscientific use of teeth
After orthodontics, many people still eat whatever they want. If they always bite hard objects such as ribs, chicken legs and nuts with their teeth after orthodontics, it will also affect the orthodontic effect and lead to rebound.
(3) Bad oral habits
After orthodontics, we still don't pay attention to the cleaning of teeth, continue the previous bad oral habits, or brush our teeth incorrectly, and the teeth and gums are not well maintained, which will also affect the effect of orthodontics and even lead to the abnormal rebound of teeth again.
(4) The doctors' operating level is low.
If the orthodontist's level is relatively low and his skills are not up to standard, it will also affect the effect, so we should choose a professional dentist with rich clinical experience to operate.
2. What about the revised rebound?
Rebound and recurrence occurred after orthodontics. It is best not to wear the previous retainer. The retainer is made according to the corrected teeth, and the retainer cannot produce orthodontic effect. Therefore, if the teeth have rebounded now, it is best not to wear them again. When orthodontic rebound is found, you should contact the doctor in time to see if the doctor can handle it. If the doctor can't handle it, he can only consider correcting it again.
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.
