1, what is the harm of orthodontics?
1, teeth become loose
Dental experts said that because under normal circumstances, each tooth has a certain physiological activity ability to buffer chewing pressure and prevent tooth injury.
During orthodontic treatment, tooth mobility increases, which is a normal reaction. Moving teeth needs to rebuild alveolar bone and periodontal ligament, because teeth are fixed in alveolar bone through periodontal ligament, so teeth will become loose.
However, after the teeth are corrected to the normal position and stop moving, the teeth can reattach the periodontal ligament through their own repair ability, and become stable without causing permanent damage.
Therefore, if the teeth are found to be too loose in clinic, we should stop exerting force and let them recover for a period of time before continuing to exert force.
2. Influence on roots
This is because the root surface is also undergoing reconstruction activities such as absorption and proliferation during orthodontic treatment. After treatment, the root will return to normal by its own repair ability, but if the treatment force is too large, it will increase the risk of root absorption.
3. Influence on alveolar bone height
After orthodontic treatment, the height of alveolar bone will be slightly reduced. This is because wearing orthodontic appliances makes oral hygiene difficult to maintain, increases the chance of gingivitis, and has a certain impact on alveolar bone. After orthodontic treatment, alveolar bone will not continue to be absorbed. If good oral hygiene is maintained, alveolar bone will gradually return to normal.
4. Effect on dental pulp
In the initial stage of orthodontic treatment, there is a mild and temporary inflammatory reaction in the dental pulp, which shows that the patient has pain or discomfort in the first few days after exertion, but the experiment proves that the harm of orthodontic treatment has no clinical significance.
2. Whose teeth can't be repaired?
1. People suffering from acute infectious diseases, such as acute hepatitis and tuberculosis, should wait until their condition is stable before going to the hospital for dental surgery.
2. People with hemorrhagic diseases, such as thrombocytopenia patients and leukemia patients, have poor coagulation mechanism and are prone to bleeding more during orthodontic surgery.
3. Patients with oral local soft and hard tissue inflammation in acute phase should wait until after the acute phase to avoid local inflammation aggravation or blood spread.
4. Patients with gingival malignant tumor should not undergo traditional dental surgery to avoid local and distant spread of the tumor.
5. Patients with active angina pectoris, myocardial infarction within half a year, hypertension and heart failure that cannot be effectively controlled are not suitable for routine dental surgery.
3. When will the whole tooth be ready?
Boys 12 years old, girls 1 1 year old, it is best to have dental plastic surgery, because the deciduous teeth have just been replaced, and the jawbone still has development potential, which is conducive to better plastic surgery and normal growth after dental plastic surgery.
Of course, adults can't fill their teeth! Objectively speaking, the growth and development of adults have been completed, the suture of maxillofacial region has become bone fusion, the plasticity of bones and neuromuscular is low, the metabolic rate of adults is slow, and the biological reactivity is reduced. So adult orthodontics is much more complicated than children's orthodontics. Compared with teenagers, the treatment of adults is mainly tooth movement, and serious skeletal deformities need orthognathic surgery to correct them. The course of treatment and maintenance time are relatively long, usually taking one to two years. Most adult patients are independent, can actively cooperate with the treatment, carry out the doctor's advice well and maintain oral hygiene, so some courses of treatment will even be shortened, and the final correction effect is equally ideal.
