Orthodontics is the treatment of malocclusion by orthodontic or surgical methods. Malocclusion refers to the malformation of teeth, jaws and craniofacial surface caused by congenital or acquired factors during the growth and development of children, and malocclusion is listed as the three most common diseases of the oral cavity together with dental caries and periodontal disease, and its prevalence rate reaches more than 50% of the population.

Orthodontic answer questions.
1, why are the teeth uneven?
There are many reasons, mainly including genetic factors and environmental factors. Environmental factors include congenital factors and acquired factors.
Congenital factors refer to the fetus in the mother’s womb during the growth and development of various influences, may be the mother or fetus nutritional metabolism disorders, the mother suffered from rubella or infected with viruses, the mother was traumatized during pregnancy or birth injuries caused during childbirth.
Acquired factors refer to the effects suffered during growth and development after birth.
(1) Diseases: Certain acute infectious diseases, certain chronic wasting diseases may affect the development of teeth and jaws. Endocrine dysfunction or malnutrition, especially vitamin deficiency, may affect the development of teeth and jaws.
(2) Abnormal respiratory and swallowing functions may affect the development of teeth and jaws.
(3) Bad habits such as finger biting, upper lip biting or lower lip biting, tongue extension or tongue spitting habits.
(4) Problems that occur during the period of teething or tooth replacement. Including premature loss of milk teeth, delayed loss of milk teeth, premature loss of permanent teeth, disorder in the order of eruption of permanent teeth, etc. can cause teeth misalignment.
2.What are the dangers of uneven teeth?
First: affect the beauty of the face
Second: teeth misalignment can easily lead to unclean brushing, so it is easy to grow cavities and tartar, affecting teeth and periodontal health.
Third: Because the upper and lower bite relationship is not good, it will affect the eating, chewing function decreases, aggravate the gastrointestinal burden, thus affecting the health.
Fourth: Sometimes it also affects the pronunciation.
Fifth: Some children and teenagers are ridiculed by their classmates or buddies because of their unattractive teeth, thus becoming inferior and affecting their mental health.
So you see there are so many hazards of uneven teeth, I hope that all parents of children can pay attention to their children’s teeth, regular checkups, give children a pair of neat and beautiful, healthy teeth, but also give children confidence.
3.Is there any way to treat irregular teeth?
It is possible to correct uneven teeth. Many people think that teeth look like that, given by parents, and cannot change it. The times have changed, this old concept should also be changed. Orthodontics is also a discipline called orthodontics. It has a history of more than 100 years.
4.Can only teenagers have their teeth straightened? Can adults do orthodontics?
Like children and teenagers, adults can also do orthodontics. So believe in science, you also have the right to pursue beauty.
5.Should children be orthodontic during the period of tooth replacement?
Children do not need orthodontics during the period of tooth replacement, except for the following cases
(1) Severe skeletal deformity of the upper jaw or lower jaw, such as excessive protrusion of the front teeth, lip protrusion? (1) Severe maxillary or mandibular skeletal deformity, such as excessive protrusion of the front teeth, protruding lips?
(2) Bad habits seriously affect the development of teeth and jaws. Such as biting the lower lip habit, finger eating habit, mouth breathing habit, tongue spitting habit.
(3) Severe misalignment of individual teeth, such as twisted teeth; individual teeth are reversed (upper teeth bite inside the lower teeth).
There are also some temporary misalignments that occur during tooth replacement; these include: mild crowding, gaps between incisors, and deep bite. Parents should not worry when they see these conditions. As the child grows, these misalignments will gradually disappear or ease, so there is no need for orthodontic treatment.
6.When is the best time to correct?
Generally speaking, the best orthodontic treatment for girls at the age of 10-12, and for boys at the age of 11-13. At this time, the milk teeth have just been replaced.
However, for children with skeletal deformities, especially children with “pocket teeth”, doctors recommend early orthodontic treatment during the period of tooth replacement. Early orthodontic treatment can help to take advantage of the child’s growth spurt to interrupt the abnormal growth trend and direct it to normal.
7.What are the methods of orthodontics?
Mobile orthodontic appliances: generally used for the correction of relatively simple errors and malformations in the period of milk teeth and teeth replacement, or with fixed orthodontic appliances for orthodontic treatment. Patients can take them off and on themselves.
Fixed braces: the most commonly used orthodontic appliance. Patients cannot take them off and on by themselves.
Functional braces: mainly used for children who are still in their growth spurt during the period of tooth replacement or just after tooth replacement, functional braces can be used to correct bony malocclusions and malformations.
Orthognathic surgery: Severe malocclusion, such as maxillary protrusion, maxillary recession, mandibular protrusion, mandibular recession, can not be solved by simple orthodontics, it is necessary to combine surgical and orthodontic treatment methods.
8.How long does it take to straighten teeth?
Generally orthodontics takes about one and a half to two years. Generally children are faster than adults, and treatment with tooth extraction takes longer than treatment without tooth extraction. Complex malocclusions and malformations take longer to treat than simple malocclusions and malformations. Skeletal malformations take a little longer to correct than simple dental malformations. Each person’s situation is different and should be analyzed on a case-by-case basis, and the treatment time should also be analyzed on a case-by-case basis. After the completion of orthodontics, generally need to wear retainers for about a year and a half.
9.Will orthodontic treatment cause loose teeth? Will I lose my teeth when I am old?
When orthodontic treatment, the teeth will be slightly loosened during the process of movement, but after a period of maintenance after the completion of orthodontic treatment, the alveolar bone around the teeth will be altered and the teeth will become stable again as before. So old will not lose teeth worry is not necessary at all.
10.Why do orthodontics require tooth extraction?
About 50% of orthodontic patients need to have their teeth extracted.
The purpose of tooth extraction is to.
(1) To align crowded teeth in between extractions. Patients with II-III degree of crowding are more likely to have their teeth extracted.
(2) To use the space between extractions to align the anterior teeth, improve the arch protrusion and improve the facial shape. For example, some people have protruding lips, but after extraction, the protrusion of lips will be reduced and the facial shape will become more beautiful.
(3) Use the gap between extractions to adjust the bite relationship of the back teeth, so that the back teeth cusps and sockets are staggered and the bite contact area is maximized to achieve the best chewing efficiency.
11.Is it painful to straighten teeth?
Generally, when you first put on the fixed aligner and within 3-6 days after each follow-up visit, you will feel some pain, chewing weakness, you can eat softer food in these days. Generally the pain will gradually reduce until it disappears.
12.What tests are needed for orthodontics?
Before orthodontics generally need to do the following examinations.
(1) Bite impression: (i.e., take a model) for the doctor to diagnose and design the error and the situation, and in the future treatment process for comparison checks.
(2) Photographs: Before treatment, the doctor will routinely take pictures of the patient’s face and dentition for later comparison with the end of treatment.
(3) X-ray: Lateral cephalometric and full-mouth surface tomography films are routinely taken for each patient.
(4) Treatment planning: Based on the model, photographs and radiographs, the doctor measures, calculates, diagnoses the type of malocclusion, and formulates a detailed treatment plan. The physician then explains the treatment plan to the patient and the patient’s family and asks for their opinion. After the treatment plan is determined, the patient or the patient’s family signs the consent form.
(5) Specific treatment procedures.
(6) After the treatment is completed, the aligner is removed and the retainer is put on.
13, with periodontal disease of the teeth can be orthodontic misalignment?
Many patients with periodontal disease often find that their teeth are slowly misaligned, the gap between the front teeth has also appeared, and increasingly large, seriously affecting the facial aesthetics, many patients feel distressed by this. In fact, this situation can be solved by means of orthodontic treatment. Anyone who has undergone systematic periodontal treatment, periodontal inflammation is controlled, and the patient has mastered the method of maintaining oral hygiene himself, can wear fixed orthodontic appliances for treatment.
Generally suffer from periodontal disease of the teeth after orthodontic treatment, the teeth need to be glued on the lingual side of the fixed retaining wire to permanently maintain the position of the teeth, but also play a role in maintaining periodontal health.
14.Why do I need to wear retainers after orthodontic treatment?
After the orthodontic treatment is completed, the aligners are removed and the teeth become straight and beautiful, but this is only half of the journey, the next step must be to wear retainers. Because the teeth are still unstable in their new position, retainers are necessary to keep the new teeth in place until the alveolar bone remodels, usually for a year and a half.
There are two types of retainers: removable and fixed. Fixed retainers, also known as permanent retainers, are commonly used for adult patients.
15.Is there an orthodontic appliance that looks more aesthetically pleasing?
There are many adults who want to straighten their teeth, but are concerned about the “steel mouth and iron teeth” after wearing braces. Clear brackets are close to the color of the teeth, so they do not look very obvious. The lingual braces are attached to the inside of the teeth on the tongue side, so they are not visible from the outside.
