The basic overview is to straighten and align the disordered teeth, improve the facial side appearance and have a beautiful smile, a very common form of cosmetic dentistry. Health, through orthodontic treatment so that the teeth and gums and other periodontal tissues remain healthy; at the same time, enhance self-confidence, so that the psychological health. Function, is to improve the chewing function through orthodontic treatment, want to eat. Stability, is to keep the results of orthodontic treatment to avoid recurrence. Orthodontic population Children and adults can undergo orthodontic treatment. Chewing pain and temporomandibular joint pain caused by occlusal disorders should be treated with orthodontic treatment. There are some dental malformations that require early treatment (3 to 5 years old), such as the “ground bun”, lip biting, finger sucking and other bad habits. However, for general malocclusion in children, it is advisable to consult and check with an orthodontist when the permanent teeth have begun to erupt (8 to 10 years of age). Because at this time can be early, regular observation of children’s permanent teeth eruption process, timely detection, problem solving. The optimal age for most fixed orthodontic treatment is 12-16 years old, which some dentists call the “golden age”. Orthodontic treatment for patients with malocclusion should be optimally timed. Children’s orthodontic treatment of misalignment, in different age groups have different specific as follows: 1, milk teeth period (3 ~ 6 years old). The purpose of orthodontic treatment is mainly to promote the children’s maxillofacial orthognathism, mandibular protrusion, posterior antomandibular and other oral malpractice that impede the normal development of the maxillofacial region and normal function. 2.Teething period (6~12 years old). In this period, there may be localized dental irregularities, which generally do not need to be corrected in a hurry, but for the anterior antimandibular, functional mandibular retraction and abnormal maxillomandibular relationship need to be corrected in time. 3, permanent teeth period (12 years old ~). 12 years old or so permanent teeth began to form, this time the teeth once the teeth will not automatically disappear, can only be corrected through the orthodontic specialist orthodontic treatment can be corrected, this period is the best time for children’s dental alignment correction, the best results, a variety of dental alignment can be corrected. Orthodontic technology is developing very fast, now not only teenagers start orthodontic treatment, but also adults start orthodontic treatment. However, because adult teeth have stopped growing, orthodontics can be more difficult. The process of orthodontic treatment is actually a mutual cooperation between the doctor and the orthodontist to align the uneven teeth through braces. According to Prof. Xie, the orthodontist of CHC, the ideal orthodontic process can be divided into these stages: clinical examination, collection of diagnostic information (e.g. plaster cast, photographs of the face and teeth in the mouth, X-ray of the face and teeth, etc.), diagnosis and analysis of the medical history, preparation of the treatment plan, explanation and discussion of the consultation, commencement of the orthodontic treatment, mandatory checkups and records during and after the treatment, and after the orthodontic treatment. Wearing of retainers (retainers) after orthodontic treatment. In reality, the process of orthodontic treatment depends on the degree of deformity of the teeth of the individual, for severe deformity, the orthodontic process will also be assisted by surgical procedures to be corrected. In addition, the complexity of the orthodontic process also depends on the experience of the orthodontist and the patient’s cooperation. In conclusion, for orthodontists, as long as they cooperate with the orthodontist during the orthodontic process, they will be able to achieve the desired orthodontic results. DurationThe general expected duration of orthodontic treatment is about 2 years. However, the degree of deformity varies from patient to patient and so does the time spent on treatment. Good cooperation with the orthodontist, on-time follow-up, maintain good oral hygiene and health, and protect the orthodontic appliances from damage; orthodontic treatment time will be greatly shortened. Bracket type 1, ceramic bracket ceramic bracket has the same color and beauty as real teeth. Ceramic brackets and saliva contact does not affect its aesthetic. The use of high-quality porcelain powder manufacturing ceramic brackets and metal brackets have the same mechanical strength and function. Ceramic brackets are pure ceramic brackets, without metal grooves that can affect the aesthetics of the brackets. 2.Self-locking BracketSelf-locking Bracket is improved on the basis of traditional orthodontic bracket, and it is different from the square arch bracket, straight arch bracket, lingual orthodontic appliance and invisible orthodontic appliance which are more often used in the clinic in terms of design. It can lock the arch wire, and the arch wire does not need to be ligated, and can be fixed by mechanical special spring sheet, without the problem of aging and power decay phenomenon of the ligated rubber ring, and its friction is low, which helps to realize the light force orthodontic treatment. 3.Mini-tooth mini-tooth slot applies computer-aided design technology, which minimizes the size of the tray without affecting the function of the tray and increases its aesthetics. Balanced mini brackets have the smallest VSI index, which is the ideal choice to improve the aesthetics of orthodontic treatment. 4, ordinary brackets ordinary metal brackets are mainly metal brackets. Imported metal brackets have smooth surface, compact size, strong and durable, accurate grooves, well-made, contributing to the perfect alignment of the teeth, and the unique rounding of bracket edges reduces the adverse stimulation of the oral mucosa, and the price is moderate. 5, lingual invisible orthodontics lingual orthodontic treatment technology is the international orthodontic technology emerging in recent years, it is all the aligners installed in the tongue side of the teeth for orthodontic treatment, the appearance can not see any orthodontic treatment device. Therefore, once this technology is introduced, it is welcomed by patients with high aesthetic or professional requirements, such as actors, lawyers, teachers, and so on. 6, no bracket invisible orthodontics no bracket invisible orthodontic technology for the international cutting-edge orthodontic technology, the world’s only two organizations master this technology, by the national patent protection for 20 years. The technology uses German high-tech memory material made of a series of braces, orthodontic process is almost unnoticeable in the completion of the bystanders, does not affect the daily life and social life. Pain during orthodontic treatment is inevitable, and modern orthodontic treatment has taken many approaches to make orthodontic patients feel more comfortable as opposed to traditional orthodontic methods. These methods include: self-ligating bracket orthodontics, MBT straight wire arch orthodontics and TOMY Orthodontics. These techniques allow the locking brackets to become smaller and smoother; and improve the orthodontic treatment archwires to produce consistent, gentle orthodontic forces. Usually there will be 2-3 days of discomfort after each follow-up appointment and archwire force. However, there is no need to take any analgesic at all. The purpose of orthodontic treatment: 1. To restore the function of mastication and help digestion and nutrient absorption. 2. 2.To make the maintenance of oral hygiene easier and to prevent periodontal disease. 3.Restore the beauty of your face and make you feel more confident. 4.Correcting unclear pronunciation caused by developmental abnormalities, improving learning and working efficiency. 5.Solve the dryness of the oral mucosa caused by the inability to close the lips due to dental problems and enhance the resistance of the oral cavity to foreign infections. Contraindications periodontal disease patients, poor oral hygiene habits or good caries patients. Suffering from systemic diseases such as hyperthyroidism, diabetes mellitus, tuberculosis, mental illness, etc. Generally should not be orthodontic, severe malnutrition and pregnant women should not be orthodontic. Impact 1, unfavorable factors: can cause plaque accumulation, gingival recession, root or bone resorption and attachment loss. In the case of periodontal inflammation and subgingival calculus untreated and uncontrolled, orthodontic treatment is blind and rough, is bound to aggravate the above periodontal pathological changes and symptoms. 2, favorable factors: can remove e trauma, rebuild the normal relationship and the ability of the upper and lower jaw respectively for the overall support, dispersion of masticatory force; can also be pressed into the end of the tooth root through orthodontic force, so that the alveolar bone encompassing the thickness of the root of the tooth is deepened. Emphasized here are two concepts that appear in the treatment of periodontal disease: 2.1. Indentation of deeply overlapping anterior or elongated teeth. This is to deepen the depth of the root in the bone in order to change the state of bone resorption surrounding the root, providing a basis for artificial bone induction and tooth stabilization; “pressing in” not only flattens the maxillary and mandibular symphysis planes, but also removes the symphysis trauma factor, providing a stable environment for the displacement of elongated teeth. 2.2 Establish the overall support of the upper and lower jaws. Support is simply the ability of a supporting object to antagonize externally applied forces. Integral support refers to the integration of neighboring objects that share the burden of antagonizing externally applied forces. For example, a periodontally diseased loose tooth is precarious during mastication, but after integrating into a community, it can both participate in the function, but also can disperse the pressure of the tooth itself and traumatic early contact repeated interference, and can recuperate. Success Criteria 1.Comfortable bite and jaw. 2, beautiful color, no gray, black, natural simulation. 3.Natural shape, can not be uniform, more can be personalized. 4.Good neighbor relationship. 5, healthy gums, no swelling, no bleeding, no odor, no pus. 6, as far as possible to retain the healthy roots (recommended first orthodontic alignment), more than 95% of the retained roots. 7, no pain and other discomfort, no pain, no acid, no sensitivity. 8, edge precision, smooth through, no gap, can not be wide, can not be narrow. Attention to diet from the moment you bring dental appliances, irregular teeth are bound, do not think that after bringing the orthodontic appliances, it is once and for all, experts pointed out that in orthodontic dentistry, diet should be given attention to, improper diet, may affect the effect of orthodontics. As full mouth orthodontics generally need to be treated for 1 or 2 years, the brackets of the braces are attached to the surface of the teeth by special bonding agents, and then the archwires are fixed on them to apply a certain amount of force to achieve the purpose of orthodontic treatment of the teeth. Therefore, the braces themselves need to be easy to put on and easy to take off. At the same time, the archwire must be able to generate the appropriate amount of force to withstand a certain amount of chewing. Since they are appliances to be removed at a later date, they cannot be so tightly attached to the teeth that we can eat with impunity, and the thin archwires cannot withstand excessive biting forces. Therefore, during orthodontic treatment, we should eat less: (1) Foods that are too hard, such as ice cubes, nuts, hard crackers, sugar cane, hard candies, crabs, lobster shells, etc. We also need to quit bad habits such as pen biting and nail biting. (2) Foods that are too sticky, such as milk sugar, maltose and some cookies, and chewing gum should be chewed with no sugar content. (3) Foods that are too big, such as apples and pears, should be cut into small slices before eating. Of course, in order to avoid dental caries, sweets should be minimized during orthodontic treatment, while the process of tooth movement increases bone metabolism, attention should be paid to calcium intake and so on.
