The specific correction plan is based on the comprehensive judgment of your tooth crowding, age, denomination development, health status and facial muscle tension, and then it can be determined.
If it is slightly crowded, that is, less than 4 mm, it can be considered as dentofacial deformity, because it is generally not accompanied by imbalance between jaw and dental arch, and there are few abnormal functions of oral and maxillofacial system. The molar relationship is neutral and the face shape is basically normal.
Therefore, tooth extraction may not involve correction. Generally, the dental arch is enlarged, the molar is pushed to move far, and the crown is narrowed in the near and far direction. This process is very simple.
However, if it is moderately or severely crowded, there is still imbalance between the jaw and the dental arch, which affects the patient's face shape, and sometimes it is accompanied by abnormal function of the oral and maxillofacial system.
Therefore, it is generally necessary to pull out a certain number of teeth to coordinate the relationship between tooth quantity and bone quantity, relieve dentition congestion and reduce the recurrence of deformity, and orthodontic appliances may be used in the process.
In addition, it is necessary to adjust the occlusal relationship by using the tooth extraction gap, increase the occlusal contact area and improve the chewing efficiency.
Generally speaking, professional orthodontists will improve the functionality and aesthetics of the oral cavity to a certain extent after completing orthodontics.
For example, some people have a protruding mouth, which will become smaller after tooth extraction and the side face will become beautiful. This is an obvious change.
