Orthodontic extraction is because of the extraction method required for orthodontic treatment. Orthodontic extraction generally uses bicuspid or deformed teeth to extract. Orthodontic extraction is the selective extraction of teeth to make room for good treatment results.

Orthodontic extraction can generally achieve the effects of treating dental crowding, correcting facial protrusions, and correcting occlusal relationships.

Selective extraction of teeth to make room

Because of the need for orthodontic treatment, teeth are selectively extracted to leave space in order to obtain good treatment results.

When you have a toothache and go to the doctor with a carious cavity, the doctor generally tries to treat the tooth as much as possible, and it is not easy to extract the tooth. Even if the healthy crown is mostly rotten, if the root of the tooth is OK, you don't need to remove it. Orthodontists often need to remove four bicuspids, or sometimes wisdom teeth that have not yet developed, due to the need for correction. Sometimes in addition to the four bicuspids, for the needs of treatment, it is necessary to remove the wisdom teeth that have not even grown, and that are not very useful, so that a total of 8 teeth are removed. This makes patients and parents unable to understand and feel that it is a pity to remove so many healthy and intact teeth. Some parents also ask, what should I do if there is such a large gap after tooth extraction? Some elderly people in the family heard that it was so distressed to pull so many teeth and said that they would loosen their teeth and fall off early.

It is understandable that some patients or parents are hesitant about tooth extraction. However, if it interferes with the doctor's determination of the correct treatment plan, even if some cases are barely corrected without extraction, the final result is very unsatisfactory, and some cases cannot be treated without extraction.

In fact, extraction orthodontics is very common in the treatment of orthodontics, about 65%, and even if the teeth are not orthodontic, most people's wisdom teeth have to be removed. In the history of the development of orthodontics, tooth extraction has stood the test of clinical practice. Some diseases, such as severely crowded teeth, must be corrected by extraction. If you do not extract your teeth, not only will the deformity not be corrected, some exhausted teeth will soon relapse back to the original deformity. Some cases of protrusion, reverse jaw, and open jaw cannot be corrected. After extraction of the teeth, there are gaps. These gaps generally do not require dental implants. Doctors use them to move the teeth for the purpose of orthodontic treatment. After the orthodontic treatment is completed, the interstitial spaces are mostly closed.

Correction of crowding: The malocclusion of the malocclusion, which is obviously insufficient, must be corrected. The coordination of tooth mass and bone mass can be achieved through tooth extraction, and the balance between the dental arch and perioral muscle tension can stabilize the correction effect and prevent the deformity from recurring. The main purpose of orthodontic extraction is to relieve crowding and align the teeth.

Correct facial anterior process: Patients with double-arch arches or patients with sagittal and non-vertical arches also need to obtain gaps through tooth extraction in order to achieve anterior, adducted and posterior teeth to obtain stability, balance, Beautiful facial profile.

(3) Correct the occlusal relationship: Some patients have very uniform teeth, but some open the jaw, reverse the jaw, and have no occlusal relationship. This situation is also common in tooth extraction.

In patients with insufficient bone mass, the width of the permanent crown is too large, and most of these patients need to be treated with extraction. After the eruption of the first permanent molar in the early stage of the tooth replacement, the jawbone basically no longer develops forward. After the mandibular incisors and lateral incisors have emerged, if crowding occurs, the degree of crowding in the dental arch is again determined by mixed dentition analysis. For patients over 4mm, the children and their parents must work closely with the orthodontist. Under the correct guidance of the doctor, the canine canine and the first and second molars can be removed sequentially and in a timely manner, which can ensure the permanent and maxillary permanent teeth. The normal eruption sequence allows the excess gap after replacement of the primary molars to be used by the subsequent permanent teeth, instead of allowing the first permanent molars to be moved proximally and centrally.

After the occlusion is completed, severe crowding occurs, and extraction can be corrected. The extraction principle is to extract as little as possible, and those with a crowded degree of 5-9mm should only remove one permanent tooth; those with a crowded degree of more than 10mm can extract 2 permanent teeth.

1. Remove the first double canine:

For most cases that require extraction, the most commonly removed tooth is the first double canine, which is the first tooth behind the canine, at the junction of the anterior and posterior segments, and the gap after extraction is easy. It is used to relieve the crowd of anterior teeth or to adduct anterior teeth. Because its shape is similar to that of the second bicuspid, the canine and the second bicuspid can have a good abutment relationship after the gap is closed.

Generally speaking, the removal of bicuspid teeth has little effect on the shape and function of the dental arch, and the correction of the wrong occlusion is of great significance.

In order to maintain the left and right symmetrical arrangement of the teeth after correction, the midline is not biased, and the left and right sides are usually extracted at the same time. Also, in order to establish a good occlusal relationship between the upper and lower dental arches after the correction, the upper and lower dental arches are usually extracted at the same time. In this way, the most commonly used extraction treatment plan is to remove the first double canine from top to bottom and left to right. Of course, some patients may also adopt other extraction schemes, or do not need to extract teeth at all, which is determined after specific diagnosis and analysis of specific cases.

2. Extraction and interdental The purpose of orthodontic extraction is to obtain a gap, which is used in the process of correction. But in fact, the gap required by each patient is different, and the extraction must often be symmetrical. Generally, the tooth cannot be extracted on one side, and it is impossible to extract only half of the teeth. Therefore, the gap and the extraction site may be needed Cases where the gaps provided are not exactly equal. The situation usually encountered is that the extraction gap may be larger than the required gap, but the orthodontist can always close the extraction gap completely without leaving gaps. What is the reason? In the process of correction, some dislocated teeth moved to normal. Position, and the protruded tooth is retracted internally, which is the result of the corrective action. During this process, the posterior teeth often move forward due to the reaction force, and sometimes this movement is also part of the treatment plan. In this way, the extraction gap gradually decreases during the relative movement of the front and back teeth, so that it is completely closed without leaving gaps between the teeth. Some patients worry that large gaps may be left after tooth extraction, and concerns that must be eliminated by means of dental implantation are unnecessary. ^[1]
