Wang’s mother, who lives in Hankou, has been troubled recently because her 3-year-old son has “geodesic” and she doesn’t know what to do. Because Wang’s mother is also a “geodesic”, she was afraid that she would inherit it from her own child. For this reason, Wang’s mother came to the Department of Orthodontics of the Peking Union Medical College Hospital for consultation. After the oral examination, Dr. Yuan Zhenglin of the Department of Orthodontics of the Peking Union Medical College found that the child was obviously “geodesic”, and the lower front teeth were supposed to bite on the lingual side of the upper front teeth, but they ended up biting on the labial side of the upper front teeth. The child’s chin protruded significantly to the front, and there was a significant bony depression around the nose. Based on the results of the examination, the child’s mother also had a “diastema” and the child had a hereditary predisposition to retrognathism. What should be the treatment? When is the best time for treatment? Wang’s mother consulted with Dr. Yuan Zhenglin about these questions. According to Dr. Yuan, the best time to treat a child with “ingrown teeth” is between the ages of 3 and 5. At this time, children’s teeth are all milk teeth and have not yet started to change, which makes orthodontic treatment more appropriate. Children only need to wear a tailor-made mobile orthodontic appliances, usually wear 2-3 months will have a significant treatment effect. Some people feel that if the “enamel” is not very obvious, they should not bother with it, is this true? Dr. Yuan said, “No! If a child’s “geodesic” is allowed to develop without treatment, the child’s “geodesic” will become more and more serious, the chin will continue to elongate forward, and the upper lip around the nose will become more concave, and it will be very difficult to correct it when the child grows up. Not only does it cause a great psychological burden to the child and make him/her feel inferior, but also the parents often regret it. After listening to Dr. Yuan’s introduction, Wang’s mother promptly underwent orthodontic treatment for her son’s “geodesic”. So far, after only 2 months, the child’s “geodesis” has been significantly corrected. In order to consolidate the treatment effect, the child only needs to carry another six months. For this reason, Wang’s mother is no longer worried and she smiles happily as she sees her son’s “geodesis” disappearing day by day. Therefore, we would like to remind all parents that once you find out that your child has “geodesic”, please go to the orthodontics department for treatment in time, all for the sake of your child.
