In the summer, there are many friends are consulting orthodontic problems. We will help you summarize the orthodontic misconceptions: Misconception 1, orthodontics must wait until the end of the child’s tooth replacement? Different individuals have different problems, and the timing of the start of orthodontics is not the same. In general, the best age for fixed aligners (brackets) for orthodontics is about 12-14 years old, all the replacement of milk teeth completed. However, when the child has “envelope”, serious buck teeth, “small chin”, early loss or retention of milk teeth, permanent teeth have not erupted and bad oral habits such as lip biting, finger sucking, mouth breathing, snoring, etc., they should go to the hospital as soon as possible. Some upper and lower jaw development problems should be “found and treated”, the earlier the treatment, the less harm caused and the impact on facial development. In addition, orthodontics is not the patent of young people, as long as the periodontal condition is good, any age can be orthodontic treatment, but adults receive orthodontic treatment will be subject to certain restrictions, orthodontic difficulty has also increased. Myth 2, orthodontics must be extracted? Tooth extraction has become a reason why many people are discouraged from orthodontics. The purpose of tooth extraction is to provide orthodontic space, a common means of solving dental crowding, protrusion, about 60% of patients clinically need to extract teeth orthodontic treatment. Of course, for patients with milder severity, a variety of methods can be used such as lateral expansion of the dental arch, lamellar cutting (moderate grinding of narrow teeth), and pushing the teeth backward. It is up to the professional orthodontist to decide which method is more suitable according to the different conditions of the patient. For patients who really need to extract teeth orthodontic treatment, it is the use of the extraction gap to align crowded teeth, inward protrusion of the front teeth, improve facial shape, and will not cause damage to health, standardized orthodontic treatment can make the final alignment of teeth tight, restore the normal tooth adjacent relationship, will not leave a gap, not to mention the damage to the body. Myth 3, teeth will loosen after orthodontic treatment, and will lose teeth when you are old? This misconception confuses orthodontics with periodontal disease. The real culprit of loose teeth is periodontal disease. When the oral environment is poorly maintained, plaque on the surface of the teeth is not cleaned in time and further acts with the minerals in saliva to form tartar, which slowly builds up over time and infects the tissues around it causing periodontitis. The tissues around the supporting teeth, such as the alveolar bone, are resorbed due to periodontitis, and the area of the tooth root surrounded by the alveolar bone decreases with the resorption of the alveolar bone, and finally loosening and loss of teeth occur. It is undeniable that the degree of loosening of teeth will increase during the orthodontic process due to stress and alveolar bone reconstruction, but it will recover on its own when the orthodontic treatment is over and the teeth are no longer under stress, so long as the oral environment is well maintained and periodontitis is avoided, there will be no problem of loosening and loss of teeth in the future. Need to pay attention to and pay attention to: in the orthodontic process, in addition to the regular careful brushing, the brackets around clean, you can also use dental floss, gap brush, flosser for thorough cleaning of the teeth. Myth 4, orthodontics is very painful, can not eat normally? Orthodontics is not as terrible as many people imagine, the development of orthodontic technology today is increasingly inclined to light force orthodontics, for this problem, the current qualified hospitals are basically using self-ligating brackets series, through its compact shape and low friction, light force orthodontic features, to provide patients with a safe and comfortable orthodontic experience, so that patients do not feel pain or only slight discomfort, after a follow-up visit to add force to the teeth soreness and swelling The soreness and weakness of chewing will usually disappear within two to three days. As for the diet, during the orthodontic period, you need to pay attention to avoid eating too hard, too sticky food, but other basic can eat, will not affect the normal diet. Misconception 5, orthodontic appliances only metal brackets? There are a variety of types of aligners, in addition to the traditional metal brackets, such as ordinary metal bifid brackets, metal self-locking brackets, and close to the tooth-colored aesthetic ceramic brackets, visually color difference is not large, there are invisible aligners, lingual aligners can basically do completely “invisible”, so that you do not know in the correction process. Patients can make a choice according to their own needs and the advice of a professional physician. Myth 6, the greater the orthodontic force, the more frequent follow-up visits, you can shorten the course of orthodontic treatment? Tooth movement is a slow physiological movement, an average of 1mm a month at most, in fact, a very small force can start the bone reconstruction of tooth movement, too much orthodontic force will not only not accelerate the movement of teeth, but will be more than the physiological tolerance limit to stop the movement of teeth or cause unnecessary alveolar bone submarine resorption. Too frequent follow-up visits can also cause the teeth and periodontal tissues to lose their resting time, with some undesirable consequences. Orthodontic treatment must not be carried out in an unproductive manner and must respect physiological laws. Generally fixed orthodontic treatment takes about 2 to 2.5 years, but with the maturity of self-ligating orthodontic technology and invisible orthodontic technology, to a certain extent, to shorten the treatment cycle and reduce the number of follow-up visits. Myth 7, remove the aligner is a great success, wear retainer does not matter? After a long period of orthodontic treatment, you finally get a mouthful of straight teeth. To keep this hard-earned result from being short-lived, a long retention period is required. At the end of the initial period of orthodontic treatment, the orthodontic teeth can easily relapse back to their original position because the muscle power balance reconstruction is not yet complete, periodontal tissues are not restored to balance in their new position, bad oral habits are not broken, and growth and development are not completed, so wearing retainers is crucial. They are usually worn for at least 2 years, and the patient still needs to have regular follow-up appointments according to the doctor’s requirements and wear the retainer under the doctor’s guidance. Hawley retainers, plastic compression retainers, lingual retainers
