With winter break coming up, many children and teenagers want to take advantage of their vacation time to have their teeth “cosmetically corrected”. In our daily orthodontic clinic, we often have patients with questions and confusion. They want to have a set of neat and beautiful teeth, but they do not know how to choose the way of orthodontics, and they are also worried about the adverse consequences of orthodontics. A, only after the replacement of teeth at the age of 12 can be orthodontic traditional concept that only at the age of 12 can be orthodontic. This concept is actually one-sided, and even harmful. The actual developmental deformity is actually a developmental deformity that is best prevented and corrected during the growth and development process. For the teeth “envelope”, small chin, facial asymmetry, serious buck teeth and serious crowded teeth, facial muscle function abnormalities such as open-mouth breathing during sleep, various oral habits such as biting the lower lip, lateral chewing, etc., which affect the normal development of the facial bones and oral function, it is advisable to correct the earlier the better. As the saying goes, “each person, deformity, the best period, but also different”. The American Association of Orthodontists recommends that children find a professional orthodontist to do orthodontic evaluation no later than 7 years old, in some cases at the age of 6, 7 years old to do interventional treatment, it is possible that at the age of 12 years old will not need to extract teeth. Second, orthodontics is the patent of children and young people Many people think that orthodontics is only for children and young people, middle-aged and elderly people can not be orthodontic treatment, in fact, this view is wrong. Although the growth and development of adults has stopped, the external shape of the bone has been stabilized, but the internal regeneration and reconstruction ability of the bone still exists (such as healing after a fracture), in general, adults without serious periodontal inflammation, teeth can be orthodontic. For 60-year-old adults and 12-year-old children, there is not much difference in the effect of orthodontic force on the movement of healthy teeth. The number of adult orthodontics in Europe and the United States accounted for more than 1/3 of orthodontic patients, here we need to emphasize in particular: older, orthodontic difficulties may also be greater; orthodontics is no age limit. Third, orthodontic pain can not normal diet After each orthodontic force, the patient will feel a little soreness within two or three days, these minor discomfort is generally tolerated and will soon disappear, is the normal reaction of the body caused by orthodontic treatment, no need to worry. As for the diet, during the orthodontic treatment can not eat harder things such as (bones, hard nuclei) and very sticky things, other basic can eat, generally after the orthodontic treatment can be normal diet. Fourth, the extraction of teeth orthodontic harmful Many patients or patients’ families often need to extract teeth do not understand the orthodontic treatment, worried that the extraction of teeth in the orthodontic treatment will affect chewing, so that the unwillingness to extract teeth and give up the orthodontic treatment, this concern is superfluous. Orthodontic treatment rearranges the teeth through orthodontic force, and in the process of rearrangement, a certain gap is often needed to align the crowded teeth, or to improve the facial shape of some patients with buck teeth by internalizing the protruding incisors. Where does the space come from? Extractions can provide the available space. From more than 100 years of orthodontic history at home and abroad, there is no significant harm in extraction compared to non-extraction orthodontic treatment. Fifth, orthodontic teeth after the old teeth easy to lose Some parents worry that orthodontics will cause loose teeth in old age, and even early loss of teeth, this view is not scientific. Orthodontics is to induce tooth movement through light orthodontic force, is a slow biological alteration process, the side of the moved teeth bone resorption, the other side of the new bone reconstruction, and finally make the teeth move to a normal position. The process is gradual and the teeth are stable. Regular orthodontic treatment does not cause trauma to the teeth or periodontal tissues. But in the orthodontic process must be well brushed and maintain good oral hygiene. Sixth, the shorter the orthodontic time the better The amount of tooth movement is limited, generally moving 1.5 mm per month, moving too fast will lead to tooth loosening. According to the severity of each individual’s misalignment, the course of treatment is not the same, generally 1.5-2.5 years or so, the clinical course of some very serious cases up to 3 years or more is also very normal. Some doctors or patients to shorten the time, do not follow the scientific rules, exert too much orthodontic force, the result is that the patient’s pain is heavier, tooth loosening, serious cases will cause the patient orthodontic tooth loss. Seven, choose what kind of braces metal, clear braces, lingual braces, invisible braces which is more suitable? Is the more expensive the better? First of all, aligners are just a tool for doctors, all the aligners are ultimately to achieve good treatment results. Imported aligners are better than domestic aligners in terms of manufacturing process, and orthodontists will evaluate the patient’s situation to help choose the right aligner. The choice of aligners is important, but the doctor’s level of treatment is the key to determine the quality of orthodontic treatment. Eight, orthodontics is very simple, find who is the same Orthodontics is a very complex treatment process, dentists in basic dental study after graduation to receive special orthodontic training, obtained the orthodontist qualification to be competent. Each step is critical in the examination and diagnosis of orthodontic patients, the development of a reasonable orthodontic plan, and even the entire orthodontic process. Each doctor’s treatment plan may be different, and we often encounter some cases of orthodontic failure, such as the wrong teeth were extracted or the timing of treatment was delayed, and these losses are irreversible. Therefore, it is recommended that patients choose carefully and try to choose a qualified orthodontist from a regular medical institution to complete the orthodontic treatment.
