Orthodontics is divided into four steps.
1, new diagnosis.
When patients decide to undergo orthodontic treatment, they need to go to the orthodontics department of the hospital for corresponding examinations, such as taking photos of dentures' curved sections, taking photos (for comparing the effects in the later period of treatment), taking X-ray positioning photos, checking the health status of the whole mouth, making model analysis and X-ray cephalometry.
2, tooth extraction.
Doctors will try to avoid tooth extraction when doing corrective treatment, but for patients with severe crowding and protrusion, they will extract teeth as needed. The main food of apes is raw meat, so their jaws are very large and their masticatory muscles are well developed. In civilized times, people are more accustomed to eating cooked meat, so they don't need so strong chewing power, and their jaws and muscles will atrophy and degenerate.
But teeth decay slowly, so modern people's teeth usually can't be discharged in the mouth. Tooth extraction can put those teeth that are irregular because of crowding back in place. Patients need not be too afraid of tooth extraction. If you don't pull out your teeth and barely arrange your dentition, it is likely to lead to unstable correction effect and easy recurrence.
3. Choose electrical appliances.
At present, the most commonly used appliances are fixed appliances and invisible appliances without brackets. The former has the advantages of low friction, fast correction speed, low price and little damage; However, the disadvantage is that the bracket needs to be attached to the tooth surface, which can not be disassembled at will during orthodontics, and the appearance is not very beautiful, so it is difficult to care for oral hygiene during orthodontics.
Invisible dental appliances have the advantages of beauty, comfort, hygiene and convenience, but they are not suitable for everyone, and are suitable for patients with less serious tooth dislocation. Because its ability to correct teeth is not as good as that of fixed appliances, and it needs to be replaced and cleaned regularly, its price is slightly higher, and it is suitable for adults with better economic conditions and strong self-discipline. Choosing fixed appliance is more suitable for teenagers with weak self-control ability.
4. Wear retention period.
Because the periodontal tissue is in a state of reconstruction, the teeth are slightly loose during the correction process, and it is normal for patients to feel sore and weak when chewing.
Extended data
After putting on the equipment, you need to pay attention to:
1, avoid chewing hard and sticky food, meat food should be stewed, and hard fruits such as apples and pears can be cut into pieces;
2, pay attention to oral hygiene, otherwise it will easily lead to dental caries and gingivitis and even periodontal disease;
3. Insist on wearing it and follow it up regularly, once every 4 weeks or so. Replace the archwire and braces according to the correction situation and adjust the strength. Generally, the average course of treatment is about 2 years, and the contact appliance is longer.
