The science of straightening teeth and relieving misalignment and malocclusion is orthodontics. Orthodontics focuses on what misalignments show, what types there are, what causes all these misalignments, how to confirm the diagnosis, and how to correct them more effectively. However, with the development of this discipline, it is no longer limited to aligning teeth, but also involves resolving jaw and craniofacial incongruities so as to achieve overall facial harmony and beauty. Everyone wants to have a set of straight and beautiful teeth, but they don’t know how to choose the way of orthodontics, and even have some misunderstandings about orthodontics, worrying that orthodontics will bring adverse consequences. Misconception 1: only to the age of 12 years old teeth replacement can be corrected The traditional concept that only to the age of 12 years old can be corrected. This concept is actually one-sided and even harmful. Malocclusion is actually a developmental malformation, it is best to prevent and correct during growth and development. For the teeth “Baodi”, small chin, facial asymmetry, serious buck teeth and serious teeth crowding, facial muscle function abnormalities, which affect the normal development of the facial bones and oral function, it is advisable to correct the earlier the better. Myth 2: Orthodontic treatment is the patent of children and young people Many people think that orthodontic treatment is only for children and young people, middle-aged and elderly people can not be orthodontic treatment, in fact, this view is wrong. Adults, although growth and development has stopped, the external shape of the bone has been stabilized, but the internal regeneration of the bone remodeling capacity still exists, generally speaking, adults if there is no serious periodontal inflammation, teeth can be corrected. Myth 3: Orthodontic pain can not be normal diet Each orthodontic force, the patient will feel a little soreness in two or three days, these mild discomfort can be tolerated by the general public and will soon disappear, orthodontic treatment is caused by the body’s normal reaction, do not have to worry about. As for diet, during the orthodontic treatment, you can not eat hard things such as and very sticky things, other basic can eat, generally after orthodontic treatment can be normal diet. Myth 4: extraction of teeth is harmful Many patients or patients’ family members do not understand the need for extraction of teeth for orthodontic treatment, and they worry that the extraction of teeth in orthodontic treatment will affect the chewing, so that they give up orthodontic treatment due to the unwillingness to extract the teeth, and this concern is superfluous. Orthodontic extraction is the correction of some malocclusion must take steps, orthodontic treatment through the orthodontic force on the teeth to rearrange, and in the process of rearrangement often need a certain gap to align the crowded teeth, or for some buck teeth patients inward protruding incisors, to improve the face shape. Myth 5: Teeth are easy to fall off in old age after orthodontic treatment Some parents worry that orthodontic treatment will cause loose teeth in old age, or even early loss of teeth, which is not a scientific point of view. Orthodontics is through light orthodontic force induced teeth to move, is a slow biological remodeling process, be moved on one side of the bone resorption of the teeth, the other side of the bone newborn reconstruction, and ultimately make the teeth move to the normal position. The process is gradual and the teeth are stabilized. Regular orthodontic treatment will not cause trauma to the teeth and periodontal tissues. Myth 6: The shorter the orthodontic treatment time, the better The amount of tooth movement is limited, generally 1.5 millimeters per month, and moving too fast can lead to tooth loosening. According to the severity of each individual’s misalignment, the course of treatment is also different, generally 1.5-2.5 years or so, clinically some extremely serious cases of the course of treatment up to 3-7 years is also very normal. Some doctors or patients to shorten the time, do not follow the scientific law, exert too much orthodontic force, the result is that the patient’s pain is heavier, tooth looseness is large, and in serious cases, the patient will cause orthodontic tooth fall off. Myth 7: Imported orthodontic appliances are better than domestic ones Imported orthodontic appliances are better than domestic ones in terms of production process, but they are all designed in accordance with the size of foreigners’ teeth, and if they are mechanically applied to the orthodontic treatment of the nationals, the clinical results may be disastrous. Therefore, when applying imported orthodontic appliances, patients or parents may ask the orthodontist whether corresponding measures have been taken to make up for the above defects. The choice of orthodontic appliances is important, but the doctor’s diagnosis and treatment level is the key to determine the quality of orthodontic treatment. Myth 8: Orthodontics is very simple, looking for anyone is the same Orthodontics is a very complex treatment process, the general dentist can only be competent after at least 1 year of training in a specialized orthodontic institution and obtaining the qualification of orthodontist. Each step of the orthodontic patient’s examination, diagnosis, development of a reasonable orthodontic plan, and even the entire orthodontic process, is critical. We often come across some cases of orthodontic failure, such as pulling out the wrong tooth or delaying the timing of treatment, and these losses are irreversible.
