When a child begins to have teeth, we will find that it is normal that the maxillary teeth are a little outside and the mandibular teeth are a little inside after the child's teeth grow out; If the child has some bad habits, he will gradually find that the mandibular teeth move forward and gradually the mandibular teeth surpass the maxillary teeth. In the meantime, when we find that the relationship between maxillary and mandibular teeth is normal, we should ask the doctor to make a device to adjust it. There is a very simple way to make early adjustments. We can make a sling to wear on our head, which can limit the tendency of mandibular extension.

Second, the adult plot correction:

For the malocclusion caused by maxillary retraction, it is necessary to move the maxilla forward by osteotomy, that is, to correct the malocclusion by moving the maxilla forward as a whole through special osteotomy.

At the same time, the depression in the middle part of the face was also improved obviously after the maxillary moved forward. After malocclusion correction, if the nose of individual patients is low, rhinoplasty can further increase the three-dimensional sense of the face.

For patients with malocclusion of maxillary retraction and mandibular protrusion, maxillary osteotomy should be moved forward and mandibular osteotomy should be moved backward at the same time, and mental osteotomy should be done if necessary.

"Land parcel day" has the following treatment schemes:

1. Preoperative orthodontic treatment: creating good conditions for surgery.

2, surgical treatment: according to different diagnosis, design different surgical methods, do different surgical treatment, surgical treatment is the key to correct the "ground", but also the most important part.

3. Orthodontic treatment after operation: Blending treatment: Some patients still need to do orthodontic treatment or adjust the occlusal relationship after operation, so as to further make the occlusal relationship reach the best state.

4. Psychological adjustment before and after treatment: Because the appearance of patients with "Dibaotian" has undergone fundamental changes after treatment, it is difficult for some patients to accept this change, even if it is benign and develops towards good beauty. Therefore, we believe that some patients with dentofacial deformities need psychological counseling and sometimes even psychotherapy.

What are the methods of correction?

Movable appliance: it is generally used to correct simple mistakes and deformities of deciduous teeth and dentition, or to correct them with fixed appliances. The patient can take it down by himself.

Fixed chair orthosis: the most commonly used orthosis. The patient can't take it off himself.

Functional chair appliance: it is mainly used for children who are still at the peak of growth and development during or just after tooth replacement. The functional appliance can correct skeletal malocclusion and deformity.

Orthognathic surgery: Serious dentofacial deformities, such as maxillary protrusion, maxillary retraction, mandibular protrusion and mandibular retraction, need to be corrected by surgery and orthodontics if simple correction cannot be solved.
