I. Corrective treatment course Malocclusion is a developmental deformity in children, orthodontic treatment is to make the teeth in the alveolar ridge move to the normal position, which is a biological remodeling process, so the course of treatment is longer. Generally, it takes about 1 year to treat the malocclusion during the period of milk teeth and replacement teeth, and 2 years to treat the permanent teeth, and it takes longer time for difficult patients and special cases. Orthodontic treatment is an investment in health and beauty, different from purchasing a commodity, its cost varies according to the degree of deformity, the type of braces, the degree of cooperation of the patient, age, course of treatment, etc., please consult with your treating doctor before deciding on the treatment for the approximate current charges. Third, receive orthodontic treatment must pay attention to the problem 1, pain and discomfort: the first wear orthodontic appliances and each follow-up after the force, the teeth may appear mild reactive pain or discomfort, usually lasts for 3-5 days can be reduced and disappeared, if the pain is not reduced for 3-5 days instead of aggravated, or other situations, you need to contact with the doctor in a timely manner to check, in order to avoid accidents. 2, oral hygiene: patients wearing fixed braces should pay special attention to oral hygiene. In the morning, evening and after eating, the teeth must be brushed before the follow-up, and the soft scale of the teeth and the retained food debris should be brushed carefully, otherwise it is easy to cause gingivitis, periodontitis, decalcification of the teeth and dental caries, which will affect the orthodontic treatment and the oral health. For patients who cannot maintain oral hygiene well, the doctor will have the right to terminate the treatment in order not to affect oral health. 3.Protection of orthodontic devices: during the treatment of fixed orthodontic devices, you can’t eat hard and sticky food, and you can’t eat big piece of food after making it small to prevent the damage of orthodontic devices. If you find that the band ring is loose, the arch wire is broken, etc. and the oral function is affected, you should contact the doctor in time to determine whether you need to come to the hospital for treatment. If the orthodontic appliance falls off or is damaged, you have to pay the relevant fees for the follow-up in the hospital. 4. Follow-up on time: During the process of orthodontic treatment, it is necessary to follow the doctor’s instructions for regular follow-up. Generally, after putting on the fixed orthodontic appliances, we will have a follow-up once every four weeks or so. If you do not have a follow-up on time or do not go to the hospital for a long time, the orthodontic teeth will lose the therapeutic control, and there will be abnormal displacement of the teeth or no progress in the treatment, and so on. For patients who do not come to the clinic for more than 2-3 months without any reason, it will be regarded as automatic termination of the treatment and the paid fees will not be refunded. If you want treatment again, you need to re-register and start again according to the new patient program, and the fee will be charged according to the new patient. 5.Attention to safety: patients who need to use headgear for external lip arch must wear it for a sufficient amount of time designated by the physician every day. When removing the external lip arch, the hand should be held steady to remove the elastic ring from the external lip arch first, and then the external lip arch, so as to avoid accidental injuries to the teeth and facial tissues and organs. 6.Extraction problem: Although patients and doctors are reluctant to extract teeth, there are still about 65% of malocclusions that must be corrected by extracting teeth. 7.Growth type control of the growth of the dentition: patients before the age of 18 are in the growth period, if the jaw growth type abnormalities, the treatment results are difficult to be satisfactory, abnormal growth in the retention period can also be manifested as deformity recurrence, serious developmental abnormalities may need to be combined with surgical procedures to go for further treatment. Part of the orthodontic treatment needs to utilize the patient’s normal growth potential, if the patient can’t follow the doctor’s instructions and actively cooperate, the treatment will be lost. 8, with the problem: orthodontic process, the patient or parents to comply with the doctor’s instructions to ensure that the role of the braces time 9, efficacy of the problem: although the vast majority of aesthetic and most of the orthodontic treatment can improve the appearance of the patient, but orthodontic treatment is not a cosmetic surgery, can only be carried out for the movement of the teeth, the movement of the soft tissues and the teeth are not exactly the same concept of movement. The physician’s design program takes into account the patient’s requirements for health, aesthetics, function, stability and other factors, may not be able to fully meet all of your requirements or special preferences, but we will do our best to provide you with the current level of medical treatment can be achieved by the better treatment results. Fourth, to maintain the problem “after the completion of treatment because of individual differences, growth and development and heredity, deformities have a tendency to recur” (Chinese Medical Association, Dental Branch, edited by the Oral Clinical Practice Guidelines), the doctor will take all means to prevent delayed recurrence, which requires the patient to cooperate! After the treatment is completed, you need to wear a retainer for about 2 years, and a few patients need to keep it for a longer period of time, or even for a lifetime, in order to prevent recurrence. In the event of a relapse, the patient can only be re-treated and charged for the treatment. At the same time, the shape of the patient’s jaw and face will change as he/she grows older, some of which will affect the alignment of the teeth and the bite.
