With the progress of society and the improvement of human civilization, more and more Chinese people are receiving orthodontic treatment. Orthodontic treatment is not only a way to get a beautiful face, a stable bite and a healthy environment around your teeth, but also the beginning of your confident life. Parents tend to compare how many classes their children have attended and what specialties they have practiced. Do you know that if your child does not have a beautiful face, you will lose at the starting line without waiting for your child to get started! First of all, let’s understand what is meant by malocclusion? The so-called malocclusion is in the process of children’s growth and development, due to heredity, disease, endocrine disorders, malnutrition, functional disorders, oral bad habits, replacement of teeth obstacles, and the impact of some other factors, resulting in dental, jaw, facial deformities, such as misalignment of the teeth, the upper and lower arches of the dental relationship of the anomalies, abnormalities in the size and shape of the jawbone location of the abnormalities of the face deformed and so on, is called misalignment malocclusion. Why is the number of Chinese people with circumcised teeth so huge? The most important reason is the increasing rate of caries in baby teeth and the lack of attention to the impact of bad habits on malocclusion. Oral malpractice is defined as doing the same action over and over again, consciously or unconsciously, at certain intervals of time, and continuing, resulting in malocclusion of the oral and maxillofacial region. Oral bad habits are one of the most important causes of malocclusion, accounting for about 1/4 of the causes of all types of malocclusion.Various bad habits in children can cause an imbalance of muscle power between the upper and lower arches and outside the lower and lower arches, resulting in the formation of a variety of malocclusions. If parents understand the basic knowledge of malocclusion, early muscle function training for common malocclusion, will get twice the result with half the effort! The following deformities are such. 1, the relationship between the lips and teeth are not normal children should not reveal the upper gums when smiling, revealing the gums of the patient called “gingival smile”, also known as “gingival smile”. The reason for this is that either the upper lip is too short, or the upper alveolar groove is too high. Many parents think that an orthodontic treatment after the age of 12 is enough, but this is very harmful. Orthodontists have more control over hard tissues and less control over soft tissues. 12 years of age, crooked teeth can be straightened, but unfortunately, the upper lip is still not able to wrap the teeth, and the gums have little effect on the smiling face. Countermeasures: For kindergarteners, we recommend that parents allow their children to train early in the blowing movement: blowing a flute, blowing a cock, whistling, whatever. For elementary school children, we recommend that children use the power of the lip muscles to tightly contain cardboard (12 × 7cm) when writing homework, and then change the direction of the bite when the training is 3 to 6 months old. Be careful to use the force of the lips, not the teeth! You can also use the power of the lip muscle to swallow the rope when watching TV programs, usually after six months there will be obvious results. The above method is mainly to train the lip muscle, if the patient is bimaxillary protrusion due to open lips and teeth, the training effect is not significant. 2, open mouth breathing Normal people should use the nose to breathe, sleep should be the same. However, when the child has enlarged tonsils or adenoids, the normal respiratory channel is blocked and the child is forced to breathe through the mouth. Patients who breathe through their mouths usually have the typical tonsil face. The upper lip is shortened, the open lip shows teeth, the nose is collapsed, and both jaws protrude forward. Parents are advised to pay attention to observation, and early removal of tonsils with repeated fibrosis is recommended after the age of 5. Early establishment of nasal breathing channel. 3, tongue spitting habits Under normal circumstances, the tip of the tongue should be located behind the upper incisor, and the back of the tongue is close to the mucous membrane of the palate. In infancy, the tip of the child’s tongue is located between the upper and lower gingival pads to complete the sucking process. When the child is 4 years old, the tip of the tongue gradually moved up, many kindergarten children in the health checkup found that the tip of the tongue is still located between the upper and lower teeth or even located in the back of the lower incisors, which not only allows the child to form a circumcised sky, but also with the growth and development of the face has become more and more long, but also against the long face, that is, the people said “horse face”. Parents often encourage children to have a tongue-tie after they have discovered it. Parents often encourage children to roll their tongue back after discovery, or hold the tip of the tongue against the gum on the palate to spread the gum flat and thin. You can also train your child to flick his or her tongue. Be sure to encourage him or her to make a loud noise, as your child will be able to do so! If a diastema is already present, it should be corrected immediately at age 4. At the age of 4, children are fully able to cooperate with orthodontic treatment. Some parents are always afraid that their children will not be able to effectively cooperate with the doctor, or they are afraid that their children will not be able to chew effectively with braces, which will affect the absorption of nutrients. These views are extremely harmful, 4 years old after the child’s milk teeth roots began to be slowly absorbed, 6 years old when the permanent teeth are about to erupt, at this time, even if the parents want to correct the doctor can not do anything! Can only watch the “parietal” gradually aggravated, parents can only look at the “parietal” sigh! 4, bite muscle relaxation If the parents have a long face, we recommend that you take your child to the orthodontic clinic at the age of 4 years. The bite muscle strength is moderate in order to make the facial development proportionate and harmonious. If the bite muscle strength is too large, the child will easily form a “Chinese character face” when he grows up, and if the bite muscle strength is too small, the child will easily form a long face. Training method: after the child has finished eating, the upper and lower back teeth are closed tightly, and gradually bite hard, counting from one to ten, until the temporal acidity is loosened, repeated ten times.
