Cai Xinbei (doctor of Shuotian Dental Clinic): "Why did my daughter's teeth get misaligned in primary school?" Can she correct them now? " This question is raised almost every day in clinic. According to research statistics, besides congenital factors, the disorder of teeth and jaws is also related to oral breathing, swallowing, tongue placement, unhealthy diet and bad habits (biting pens, sucking fingers, biting lips, etc.). ), which is often the culprit. When these reasons exist, it may lead to the abnormal function of musculoskeletal system, further affect children's jaw dysplasia, and naturally form tooth skew. Traditional orthodontists can't remove functional orthodontics (Myobrace), which is the crystallization product of the research and development company MRC founded by Australian doctor Farrell in 1989. The traditional appliance is to stick the appliance directly on the teeth, and then use the appliance with memory function and elastic rubber band to directly apply force to the teeth to make them move. Traditional orthodontics tends to pull out premolars and move them out of space, and align teeth on the already underdeveloped narrow dental arch. When the space of dental arch is not enough to put the tongue, tooth extraction correction will only make the situation worse and worse, so the maintainer after traditional correction usually wears it for a lifetime. Myobrace is mainly to correct our bad oral habits and let us change from oral breathing to nasal breathing through breathing training and tongue placement. Oral breathing can not only cause dentition disorder, but also cause jaw dysplasia, allergic rhinitis, snoring and other symptoms, and even cause sleep apnea in severe cases. In addition to causing a sharp decline in sleep quality, it will further affect the quality of life and work efficiency, so breathing through the nose is correct and can play a role in filtering air. Correcting Tongue Position and Oral Habits with Functional Dental Orthodontics Almost everyone underestimates the influence of the tongue, which is composed of many muscles and its strength is far beyond our imagination. Traditional orthodontics generally gives teeth about 70 grams of strength, while the strength of tongue is as high as 500 grams, which is 7 times that of orthodontics. The correct position of the tongue should be in the space of the maxillary teeth, not in the mandible or between them. The maxillary dental arch can be enlarged by the thrust of the tongue and cheek muscles, the development of the middle surface can be strengthened, and the maxillary teeth can be arranged neatly. Therefore, as long as the tongue and cheeks are unbalanced, there will be a problem of tooth arrangement. As for Myobrace, do you need to wait until all the deciduous teeth have fallen out and the permanent teeth have grown out before wearing it? The answer is that you don't have to wait until all the permanent teeth come out. Here, Myobrace corrects oral habits again. As long as the breathing and tongue position are correct and there are no bad habits, the teeth will naturally be arranged in the right position. Therefore, even children can wear all the baby teeth. The sooner they correct their bad habits, the more helpful they will be to their children's healthy development in the future.

Myobrace only needs to be worn for at least two hours during the day, plus it can be carried all the way when sleeping at night. You can wear it when you do your homework, watch TV or play games during the day. The advantage of this way is that children can avoid the psychological impact caused by social pressure at school, and they will not wear it because of interpersonal relationships, because I believe that everyone has experienced peer pressure during their growth. In addition, one of the benefits of Myobrace correction is that it does not need an impression. Often when helping children print dental molds, they either don't cooperate or the child's vomiting reflex is very sensitive. Often in the middle of printing, children will vomit all over. A complete muscle brace correction will go through three or four stages according to different ages, that is, three or four pairs of functional orthodontic appliances with different functions need to be worn. The first stage is the oral habit correction period, which corrects the wrong tongue position and breathing mode; The second stage is the development of dental arch, which aims to make dental arch develop normally until there is enough space for teeth and tongue; The third period is dentition. After the first two periods of correction, correct oral habits and the design of appliances, it is natural to arrange teeth in the right position. The fourth stage is the maintenance period, in order to prevent the teeth from running back to the original position and ensure the correct breathing and tongue position again. Generally, the older a child is, the longer it takes to correct bad oral habits. Sometimes, in addition to these four sets of appliances, they need to wear more fixed appliances to support the dental arch to help it grow. However, it must be explained here that it does not mean that you don't need to correct it when you grow up. If you develop bad habits during your growth, you may have malocclusion or malocclusion again. The later you wear it, the higher the chance that you need to receive traditional adhesive orthodontic treatment again in adulthood. Therefore, the proportion of children who wear too many functional orthodontic appliances who need tooth extraction when they grow up will also drop sharply.
