There are two pairs of teeth in a person's life, one is deciduous teeth and the other is permanent teeth. According to the eruption time of two pairs of teeth and the time limit of their existence in the oral cavity, they can be divided into deciduous tooth stage, deciduous permanent tooth replacement stage and permanent tooth stage in medicine.
The growth pattern of human face has been basically determined in the permanent teeth period, and the diagnosis of dentofacial deformities is often clear, especially in the early permanent teeth period, which is often the peak period of growth and development, and this period is the best correction period. Girls are about 1 1 and 12 years old, while boys are about 12 and 13 years old.
Correcting dentofacial deformities is a systematic project. If the factors affecting normal growth and development can be found in time, some simple preventive corrective measures can often interrupt or prevent the further development of dental and maxillofacial deformities, which will greatly facilitate and simplify the general correction that may be needed in the future. For severe skeletal dentofacial deformities, it is sometimes necessary to wait until the growth and development of 18-20 years old is completed before orthognathic surgery can be performed.
It is worth mentioning that many parents now take their children to some informal dental clinics for orthodontics in order to save money, which not only cannot guarantee the effect after orthodontics, but also may have unexpected consequences due to technical and conditional reasons. Other individual clinic doctors lack comprehensive professional theory, rich clinical practice experience, backward technical conditions but greedy for money, which will bring unnecessary trouble and redundant burden to patients. Therefore, if the child's teeth are uneven, it is best to go to a regular hospital with complete conditions for correction.
