How to extract teeth for orthodontics? You should do this

Orthodontic extraction is a relatively common method of tooth extraction. Usually, it is used to extract the canines of the teeth or correct the gaps between the teeth. After orthodontic extraction, correction work needs to be done in time to avoid widening the gaps between the teeth. Pay attention to the health of the teeth and the cleanliness of the mouth. Try not to chew food hard after orthodontic extraction, and eat more easy-to-chew foods. You can go for a dental or oral examination every 7-9 days, pay more attention to observing the teeth, pay more attention to the roots of the teeth, supplement more calcium and vitamins to make the teeth harder, and do some dental care.

Orthodontic tooth extraction is a method of tooth extraction required for orthodontic treatment. Orthodontic tooth extraction generally chooses canines or orthodontic teeth to be extracted. Orthodontic extraction is the selective removal of teeth to make room for good treatment results.

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

Overview

When orthodontic treatment is required, teeth are selectively extracted to create space for a good treatment outcome.

reason

When you go to the doctor because of toothache or cavities, the doctor will generally try to treat the tooth and will not easily extract the tooth. Even if most of the crown of a healthy tooth is rotten, it does not need to be extracted if there is no problem with the root. Because of the need for correction, orthodontists often have to extract the four bicuspids, or sometimes they need to extract the wisdom teeth that have not yet grown. Sometimes, in addition to the 4 bicuspids, for the purpose of treatment, the wisdom teeth that have grown or even have not yet grown and are of little use must be extracted, so a total of 8 teeth are extracted. This is incomprehensible to patients and parents, who all think it is a pity to extract so many healthy and intact teeth. Some parents even ask, what to do with the large gaps after the extraction, and do they need to have dentures? Some elderly people in the family are even more distressed when they hear that so many teeth need to be extracted and they refuse to allow it, saying that the teeth will become loose and fall out early.

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

In fact, tooth extraction and correction is very common in orthodontic treatment, accounting for about 65%. Even if the teeth are not corrected, most people have to have their wisdom teeth extracted if they are in a bad position. Tooth extraction treatment has withstood the test of clinical practice in the history of orthodontics development. Some conditions, such as severe dental crowding and protrusion, must be corrected by tooth extraction. If the teeth are not extracted, not only will the deformity not be corrected, but some of the teeth that have been squeezed out with great difficulty will quickly relapse into their original deformed shape. Some cases of protrusion, underbite and open bite cannot be corrected. There are gaps after teeth are extracted. These gaps generally do not require dentures. Doctors use them to move teeth to achieve the purpose of correction. After the correction is completed, the gaps will mostly be completely closed.

Purpose

⑴ Correction of crowding: Malocclusion with obviously insufficient space must be corrected by tooth extraction. Only by tooth extraction can we achieve the coordination between tooth volume and bone volume, as well as the balance between the tension of the dental arch and the muscles around the mouth, so that the correction effect is stable and the deformity is not likely to recur. The main purpose of orthodontic tooth extraction is to relieve crowding and align the teeth.

⑵ Correction of facial protrusion: Patients with bilateral dental arch protrusion or sagittal or vertical misalignment of the dental arches also need to obtain space through tooth extraction in order to retract the anterior teeth and move the posterior teeth forward to obtain a stable, balanced, and beautiful facial profile.

⑶ Correction of occlusal relationship: Some patients have straight teeth, but some have open bite, cross bite, and no occlusal relationship. In this case, tooth extraction is also common.

Indications

For patients with insufficient bone mass, the width of the permanent tooth crowns is too large, and most of these patients need tooth extraction for correction. After the first permanent molar erupts in the early stage of tooth replacement, the jaw basically no longer develops forward. When the mandibular central incisor and lateral incisor erupt, if crowding occurs, and the mixed dentition analysis shows that the degree of crowding in the dental arch is more than 4mm, the child and his parents must cooperate closely with the orthodontist. Under the correct guidance of the doctor, the deciduous canines and the first and second deciduous molars should be extracted sequentially and timely to ensure the normal eruption order of the upper and lower permanent teeth, so that the excess space after the replacement of the deciduous molars can be used by the subsequent permanent teeth, and the first permanent molar will no longer be allowed to make a later mesial movement.

If severe crowding occurs after the occlusion is completed, tooth extraction can be performed for correction. The principle of tooth extraction is to extract as few teeth as possible. For those with crowding of 5 to 9 mm, try to extract only one permanent tooth; for those with crowding of more than 10 mm, 2 permanent teeth can be extracted.

Orthodontic tooth extraction example

1. Extraction of the first canines:

For most cases that require tooth extraction, the most commonly extracted teeth are the first bicuspids, which are the first teeth after the canines and are located at the junction of the anterior and posterior segments. The space left after the extraction can be easily used to relieve crowding in the anterior segment or to retract protruding anterior teeth. Because its morphology is similar to that of the second bicuspid, the canine and the second bicuspid can have a good adjacent relationship after the space is closed.

Generally speaking, the extraction of bicuspids has little effect on the morphology and function of the dental arch, while the correction of malocclusion is of great significance.

In order to keep the teeth symmetrical and the midline not deviated after correction, teeth are usually extracted on both sides at the same time. Similarly, in order to establish a good occlusal relationship between the upper and lower dental arches after correction, teeth are usually extracted simultaneously in the upper and lower dental arches. As a result, the most commonly used tooth extraction orthodontic treatment plan is to extract the first pair of canines on the upper, lower, left and right sides. Of course, some patients may also take other tooth extraction plans, or may not need tooth extraction at all. This depends on the specific diagnosis and analysis of the specific case.
