1, Mandibular Correction: This method of floor covering correction is also commonly used, mainly for malocclusion caused by mandibular protrusion. The operation is mainly aimed at the mandible. After extra osteotomy, the mandible receded completely, correcting mandibular protrusion, thus correcting malocclusion. After the mandibular osteotomy retreats, not only the length of the mandible is shortened, but also the maxilla rotates upward while retreating, the angle of the mandibular angle becomes smaller, and the side view becomes more beautiful. If the chin is too long, the jaw osteotomy should be shortened at the same time.
2. Maxillary osteotomy: When many friends ask how to correct the tooth wrapping bone, the doctor suggests that you choose this method. However, this method is aimed at the malocclusion caused by maxillary retraction, that is, the malocclusion is corrected by moving the whole maxilla forward through extra 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.
3. In particular, it is pointed out that in early childhood, it is only necessary to simply wear orthotics for correction. But if it is not corrected until adulthood, the only way is surgical correction. Tooth deformities like Yasuda should be found and treated early. Generally speaking, it is best to treat and correct before changing teeth at the age of 12. Most 12-year-old people who change their teeth need surgical correction. After the tooth replacement period, not only the best period of correction was missed, but also the normal development of oral cavity and jaw was seriously affected.
4. Patients with malocclusion accompanied by maxillary retraction and mandibular protrusion should undergo maxillary osteotomy and mandibular osteotomy at the same time, and mental osteotomy and plastic surgery if necessary.
