Since the entry of foreign fast food in China, “fast food era” came immediately. The need to savor the Chinese food, but also pushed the Chinese fast food; bus, opened a large station express; train, shifted into a high-speed rail. People want everything fast. As if, not fast is bound to be eliminated by the times. In fact, meditate on it, not everything is the faster the better. Vegetables and fruits grow fast, both big and beautiful. Time, let people to these vegetables, fruits turned off. A tree, the main trunk grows crooked. If we want to put it right, with similar orthodontic techniques, that is, with a continuous and appropriate size of force to push it, and constantly to the root of the tree soil loosening part of the cultivation of soil, until it completely grows right. It is not difficult to understand is too much force, the roots of the tree is bound to be damaged. In this process, the tree is like teeth, the soil is like people’s alveolar bones. If a tree can’t be straightened quickly, how can a tooth be straightened quickly? If a tooth moves too fast, it may cause periodontal tissue damage, tooth loosening, tooth loss and instability. This is how orthodontics works, speed is not enough! Modern orthodontics follows the principles of orthodontic treatment, moving your live teeth to a reasonable, aesthetically pleasing position where they remain live. Orthodontics only changes the position of the teeth, not the shape or color of the teeth. The main treatment method, one is to directly make the patient’s living teeth gradually move to a reasonable and beautiful “new site” in the scientific treatment of orthodontic professionals to continue to develop and grow; the second is to remove individual teeth, and then move the teeth in the appropriate position to a reasonable and beautiful “new site “Third, after the surgery to correct jaw deformity, the preserved teeth will be gradually moved to a reasonable and beautiful “new site” to continue to develop and grow, bringing you a beautiful and neat arrangement of oral teeth and establishing a good bite and chewing function. This process of moving teeth to a “new site” is a process that requires the normal physiological response of people’s jaws to grow and reconstruct. There is no way to change the growth rate of the jaw bone. This is the fundamental reason why orthodontics takes about 2 years, and is the essential difference between orthodontics and “teeth” fitting. Modern orthodontics has been developed for more than 100 years, and orthodontic materials and techniques have been perfected day by day. But “braces” is still the main method used in orthodontics (“braces” is the common term for the commonly used orthodontic appliances in orthodontic treatment). There are often patients who look fearful when they see “braces” and ask if they can hurry up when they hear that the treatment process takes about 2 years. The organic fertilizer culture of fruits and vegetables with a long growth period, and rely on chemical fertilizers to grow fruits and vegetables quickly, which would you like to choose to eat? In addition, with the development of orthodontic material technology, now the transparent brackets, lingual braces, invisible braces for those who are afraid of “braces” ugly patients to provide the pursuit of perfection possible. The emergence of new orthodontic appliances is more in line with the patient’s need for beauty in the orthodontic process. Based on the theoretical basis of orthodontics and the natural physiological laws of human bone growth, orthodontic patients who love beauty are advised that orthodontics cannot have a “fast food” era. Orthodontics – the heart can not eat hot tofu.
