There are three situations that require tooth extraction.
1, patients with crowded dentition.
The teeth of such patients are deformed because the number of teeth does not match the number of bones. Therefore, a certain number of teeth must be extracted during orthodontics to coordinate the relationship between the number of teeth and the number of bones, relieve the crowding of dentition and reduce the recurrence of deformity.
2. Patients with prominent faces.
This kind of patients need to pull out a certain number of teeth to get a gap, to achieve the purpose of retracting the front teeth and moving the back teeth, to alleviate facial protrusion, so as to make the patient's facial profile more beautiful.
3. Patients who need to correct the occlusal relationship.
Because of the asymmetry of upper and lower teeth, this kind of patients need to extract teeth to adjust the occlusal relationship.
Many patients would rather give up orthodontics for fear of harm to their health.
In fact, as long as you go to the orthodontics department of a regular hospital, orthodontic tooth extraction is a very common and mature treatment method, and tooth extraction will not harm the function and health of patients.
Tooth extraction treatment is to coordinate the inconsistency between tooth quantity and bone quantity.
The most fundamental reason of malocclusion is that the space of alveolar bone is not enough to accommodate all the existing teeth. Tooth extraction treatment can not only make the tooth quantity match the bone quantity better, but also make the treatment result more stable. Moreover, the oriental facial features are that the nose is not straight enough, the lips protrude forward, and the chin development is not as good as that of westerners. In order to achieve a better face shape, about 60% patients need tooth extraction correction.
After orthodontic treatment, the teeth are arranged neatly and the occlusal relationship is normal, and the oral system will be healthier. Therefore, orthodontic tooth extraction is beneficial to patients.
