Hello, dental plastic surgery is a long-term systematic project. Attention should be paid to children's dental health and development from the deciduous period, and some serious deformities should be treated early in the deciduous period. When children begin to change teeth, they should establish contact with orthodontists, check regularly, observe the situation of tooth change, and intervene in some bad habits and tooth change obstacles that may cause malocclusion. Some serious skeletal deformities, such as maxillary protrusion, mandibular protrusion and jaw opening, need to be corrected early before puberty to block the development of malocclusion and guide the normal growth of teeth and jaws.
