I have seen many parents in the consultation area asking about the treatment of children’s diastema, so here is a brief introduction to help patients with this problem. “It is one of the most common malocclusions in clinical practice. Some parents think that it does not matter if the baby teeth are anticantric, and that it will correct itself after the teeth are replaced. Some parents are so concerned about their children that they come to the hospital even before their baby teeth have grown in. In fact, there is a debate in the medical community as to when to start orthodontic treatment for “ingrown teeth”. Generally speaking, as long as the child can cooperate, the sooner the orthodontic treatment should be done after all the milk teeth have erupted, the better. This is because the “envelope” affects the normal growth environment of the upper and lower jaws, preventing the normal growth and development of the oral cavity, face and jaws, resulting in the restricted development of the middle 1/3 of the child’s face and the excessive development of the lower 1/3 of the face, which ultimately affects the aesthetic appearance. The best time to treat diastemas during the period of milk teeth is 3-5 years old, as long as the child can cooperate, treatment can be carried out, the course of treatment is relatively short, less expensive, the child only needs to cooperate with the doctor, learn to take off and wear the orthodontic appliances can be, generally will not affect the life of the diet. During the treatment period, it is usually necessary to visit the hospital once every two to four weeks for a review. Most children can complete the treatment in about six months, and the jaws of the jaws caused by the anterior teeth can be released, so that they can grow and develop normally. However, because of the hereditary and recurring nature of the antimandibular, there is still a possibility of continuing treatment during the period of dentition and permanent dentition. 2, the period of teeth This period is due to the child is changing teeth, some orthodontic appliances can not be worn, treatment is relatively complex compared to the period of milk teeth, the general use of two-phase orthodontic treatment, the first phase is mainly to use the child’s growth and development of skeletal deformities to correct, the treatment time is generally six months to a year. The second phase is after all the teeth have been replaced, and then for the treatment of teeth misalignment and other problems. 3, the permanent period The permanent period of the ground is the same as most orthodontic treatment, you need to wear fixed orthodontic appliances for treatment, the period of about 2 years, some very serious bone “ground”, but also need to cooperate with the surgery to correct adults. In short, “bunions” vary, as do the timing of the start of treatment and the principles of treatment. Even in the case of similar cases in the milking or mixed dentition, the timing of the start of treatment varies depending on the development of the tooth roots during tooth replacement. Therefore, it is best to take your child to a professional doctor for consultation when dental abnormalities are found, in order to avoid delaying treatment.
