When it comes to the sequelae of orthodontics, you don't have to be too nervous. Different manifestations of malocclusion affect facial beauty and oral function, and even lead to psychological and mental disorders of patients, which have negative effects on further studies, job hunting, social interaction and mate selection. So it is necessary to correct malocclusion, improve appearance and restore function! In the Book of Songs, the beauty of women is described as "teeth like rhinoceros", and the ancients praised the beauty of teeth: "eyes like pearls, teeth like shells", which is the purpose we want to correct. Many stars, such as S and Gao Yuanyuan, have also worn braces. If your teeth are crowded or irregular, why not try them? Everything is divided into two parts, especially in the medical field. At the same time, it may also have some adverse effects because of doctors' technical level, patients' compliance and individual differences, and the pertinence of treatment programs. So, what are the side effects of orthodontic treatment? 1, Dental caries: Oral hygiene is difficult to maintain due to the existence of orthodontic appliances during orthodontics. If you don't pay enough attention to it or the doctor can't explain it clearly, it is easy to cause tooth decay; In the process of orthodontic bracket bonding, acid etchant is used, which is a kind of damage to tooth surface enamel. We still have to face it correctly. This is also the reason why many patients' enamel is white (chalky) after correction-the performance of initial enamel caries and further tooth decay; The gap is not completely closed, and food is easily blocked, which is also a cause of dental caries; In order to get enough space during orthodontic treatment, the adjacent surfaces of teeth are sliced, and the resistance of the sliced teeth to dental caries bacteria is also the cause of dental caries. 2. Gingivitis and periodontitis: The shape of gums can be gradually reconstructed with the movement of teeth. In the course of treatment, if we do not pay attention to oral hygiene, gingivitis will occur and periodontitis will further develop. If it is not controlled in time, it will cause alveolar bone absorption and affect the treatment effect. Patients with severe inflammation can only temporarily suspend orthodontic treatment and stop moving teeth until the inflammation is eliminated. 3. Dentin hypersensitivity: At the initial stage of treatment, there is a mild and temporary inflammatory reaction in the dental pulp, which is manifested as tooth hypersensitivity, pain or discomfort. Sometimes it is necessary to enlarge the gap and slice the adjacent surface of normal teeth. If the range of slicing is too large or the enamel is too worn, it will also cause dentin hypersensitivity. 4. Inconvenient chewing: During the correction period, the existence of orthotics will affect the diet, and the growth and development of children during development will be affected. 5. The gap between teeth becomes larger: most orthodontic patients need to extract the upper, lower, left and right first premolars, and this extraction gap needs to be closed after orthodontic treatment, which is incomplete due to technical reasons or individual differences of patients; The four first molars need to be divided into teeth and wear rings, which will leave a certain gap after correction, which is not easy to close; The existing gaps and teeth are easy to form food impaction, which causes gingival inflammation and secondary dental caries. 6, mental illness: one disease is not treated, and the other is the most worthwhile. Brackets, archwires, bone supports, headgear, etc. exposed to the outside of the lips during correction have certain influence on the appearance, which may cause social obstacles, especially for adult women. Moreover, corrective treatment lasts for a long time, and its psychological impact, especially on minors, cannot be underestimated. At the same time, orthodontics is to achieve cosmetic results. Some patients are more demanding, or seek a boat through wood carving. They unilaterally pursue the star's face and tooth shape, and their own conditions are limited, so it is difficult to achieve the ideal correction goal. Once the requirements are not met, it is very easy to have symptoms of obsessive-compulsive disorder, and mental nerves are traumatized. Orthodontic treatment can only be handled according to the actual situation, improve the appearance to the maximum extent and achieve functional occlusion. 7. Loose teeth: Under normal circumstances, teeth have certain physiological activity ability to buffer chewing pressure and prevent occlusal trauma. In the process of orthodontic treatment, the increase of tooth looseness is a normal reaction and a temporary phenomenon. In the process of orthodontics, the root surface is constantly absorbing, proliferating and reconstructing. If teeth want to move, it is necessary to rebuild alveolar bone and periodontal ligament, because teeth are fixed to alveolar bone through periodontal ligament, so teeth will become loose. After the treatment, after the teeth are corrected to normal position and stop moving, the teeth can reattach the periodontal ligament through their own repair ability, and become stable without causing permanent damage. If the pressure is too high during the treatment, it will increase the risk of root resorption. Therefore, if the teeth are found to be too loose in clinic, we should stop exerting force and let them recover for a period of time before continuing to exert force. 8, alveolar bone height reduction: people who have done orthodontic treatment, alveolar bone height will be reduced more or less, it is not easy to maintain oral hygiene after wearing orthodontic appliances, increase the chance of gingivitis, and have a certain impact on alveolar bone. After the treatment, alveolar bone will not be absorbed any more. If good oral hygiene is maintained, alveolar bone will gradually return to normal. 9, gingival atrophy, gingival hyperplasia: patients with poor oral hygiene or poor hygiene habits, food residues left in the mouth, food impaction, prominent corrective devices have certain irritation to the gums, and long-term irritation forms a long-term inflammatory state of the gums. If not found and solved in time, some will lead to gingival atrophy, and some will lead to gingival hyperplasia. 10, root resorption: In the process of orthodontics, the tooth surface is also undergoing reconstruction activities such as absorption and hyperplasia. After treatment, the root of the tooth returned to normal by virtue of its own repair ability. However, if the stress is too frequent and too large during the treatment, it will increase the risk of root resorption and easily lead to tooth fracture. 1 1, temporomandibular joint dysfunction: this is the most common complication in orthodontic treatment, and it is also the most easily overlooked problem for our patients and their parents. It is also a problem that many orthodontists are unwilling to face up to, and it is also a problem that our doctors are unwilling to mention to patients. We should not forget that the ultimate goal of orthodontic treatment is to rebuild occlusal function and temporomandibular joint function. It is understandable that our patients often put the improvement of aesthetics in the first place, but besides improving the appearance of patients, it is more important for doctors to restore the normal function of patients. Teenagers are in the developmental stage, with strong adaptability of temporomandibular joint and relatively few joint symptoms; Adults have poor adaptation and reconstruction functions, and people with potential joint diseases are prone to temporomandibular joint dysfunction during orthodontic treatment. If there are joint snapping, pain, limited opening and closing, and pain in the tragus area during the treatment, you should inform the doctor in time for diagnosis and treatment; Those who have symptoms of temporomandibular joint dysfunction before corrective treatment should consult a joint specialist first. At the same time, it is suggested that adolescent patients can improve their jaw relationship by changing their jaw position, and adult patients should try their best to compensate by moving their teeth. Of course, if the doctor passes the test, you can attract enough attention and cooperation, and these complications or adverse consequences of orthodontic treatment can generally be avoided. When you know this, pay attention: have you seen the overwhelming advertisements? You'd better be cautious, cautious, and cautious again. Do your necromancer in 7 days of orthodontics, 30 days of tooth arrangement, 3 months of orthodontics, and 6 months of short-term orthodontics to improve your appearance! ! ! Let me explain a truth to you. I hope you can understand that the principle of orthodontic tooth movement is accomplished by pulling, dragging, pushing and pressing. Alveolar bone has the characteristics of pressure absorption and traction regeneration, which is used in orthodontic treatment. Don't you get it? Let me tell you a simpler fact. I believe everyone knows the proverb "100 days". Why? It takes more than three months for bones to recover from destruction. The same is true of alveolar bone, which is absorbed from the displacement of traction teeth. This is a process of alveolar bone destruction, which takes some time. This time varies according to the needs of treatment, the distance the teeth need to move, the degree of malocclusion and the individual differences of patients. Then let the teeth move to the ideal position, and the alveolar bone construction of the teeth in the new position usually takes more than three months to complete. Understand?
