Uneven arrangement of teeth, severe crowding or near severe crowding? (The congestion degree exceeds 10 mm)? At the same time, in order to arrange the teeth, meet the aesthetic requirements and ensure the stability of the corrected effect, it is necessary to extract the teeth as needed. ? Use the gap between tooth extraction to relieve crowding, make the crowded teeth in order, coordinate the tooth quantity and bone quantity, make the teeth in order on the dental arch, and establish a good occlusal relationship; Patients with crowding degree II-III are more likely to have their teeth extracted. If the teeth are not extracted and the dentition is barely arranged, the orthodontic effect will be unstable and it is easy to relapse into the original crowded malocclusion. Adjust the occlusal relationship of posterior teeth by using the extraction gap to achieve the maximum occlusal contact area and form the best chewing efficiency. Can be said to be beneficial and harmless. ? In the case of vertical disharmony of dental arch (opening and closing of anterior teeth, deep overbite), uneven width of dental arch (locked occlusion of posterior teeth, asymmetric molar relationship, midline deviation), and uneven tooth quantity of upper and lower dental arch (congenital missing teeth), orthodontic treatment of tooth extraction is given priority.
Generally speaking, orthodontic tooth extraction has no obvious harm. Usually, the doctor's first choice is the sick teeth in the mouth or the teeth that have the least influence on chewing function, which generally will not cause the decline of chewing function. Moreover, orthodontics can also improve the original teeth with poor chewing function, which not only enhances the function, but also improves the appearance. As for whether to pull out teeth, how many teeth and which teeth to pull out, doctors need to accurately measure the degree of tooth crowding according to clinical examination, X-ray examination and model analysis. In order to ensure that the teeth are coordinated up and down and symmetrical left and right, it is common to remove four bicuspid teeth in clinic. If there are wisdom teeth, it is also recommended to remove them. At the end of orthodontic treatment, the tooth extraction gap will be accurately closed by the orthodontist, so patients and parents don't have to worry. After orthodontic treatment, the function and health of teeth will not be affected. About 50%~60% of orthodontic patients in China need tooth extraction. ?
The above is the orthodontic process of tooth extraction.
The cleanliness before and after operation not only improves the appearance, but also reduces the probability of food impaction and improves the chewing efficiency. If you choose tooth extraction, there will be absolutely no harm. Orthodontic treatment is a long and slow process. Patients need a good attitude, and doctors need your good cooperation and regular follow-up. Before each review of orthodontic force, orthodontists will make a preliminary assessment of the direction and degree of tooth movement. However, due to individual differences, the alveolar bone of each patient reacts differently to orthodontic force, and the actual situation of tooth movement is also different from the estimated situation. Therefore, it is necessary to follow up the patients on schedule, so that doctors can grasp the patient's situation and the progress of denture movement in time. At the same time, regular follow-up visits can also make you accept sustained and stable orthodontic force, which is beneficial to the continuous movement of teeth, the gradual reconstruction of alveolar bone and the maintenance of orthodontic effect. If the patient does not return for a long time, it may lead to the dislocation of teeth and the rebound of curative effect, especially for patients who have pulled out teeth, the gap between teeth may become smaller or disappear, which makes the tooth extraction lose its due role and sometimes it is easy to have irreparable adverse effects. For orthodontic patients, regular follow-up visits are extremely important for your teeth. I hope you will pay enough attention to them.
