Will orthodontic treatment be painful? Can children tolerate it? Will orthodontic treatment affect the child’s food? Will it affect the child’s growth and development? Do I have to have my teeth pulled if I have misaligned teeth? This is a question that parents often ask before giving their children orthodontic treatment. The painful extraction of teeth is also a concern for most adults before receiving orthodontic treatment. Traditional fixed orthodontics starts by bonding orthodontic appliances called brackets and buccal tubes to each tooth. An orthodontic archwire is attached to the brackets with a rubber band or ligature so that the force of the archwire is transferred to the teeth. The rubber band or ligature will become loose as the teeth move, and the rubber band will age and lose its elasticity over time in saliva, thus losing its role in fixing the archwire. Therefore, the general fixed orthodontic treatment needs to be reviewed once a month for a new re-ligature. The archwires can only be loaded into the brackets very tightly in order to play the role of the archwires to move the teeth, but the frictional force is not conducive to tooth movement. The force applied to the teeth must first overcome friction to achieve enough to move the teeth, when the force added will of course be large, the force is large when the teeth will be painful. Just tie a very tight force, will produce pain, and after a few days loose will not feel, loose and uneven, the teeth move, of course, is also step by step. Low friction light force orthodontics is mainly the use of modern high-tech advanced technology manufacturing self-locking brackets. Self-ligating brackets, as the name implies, are the main orthodontic device brackets are used to lock the orthodontic archwires through the locking tabs on the brackets, without the need for elastic ligature rings or small ligature wires to fix the archwires. The friction between the metal locking plates and the metal archwires is minimal, which greatly improves the efficiency of tooth movement and reduces the force on the teeth. Of course, the pain of this treatment is also reduced because the force is much less. At the same time, the metal locking piece is not easily aged and can be continuously locked in the archwire, so it does not need to be replaced frequently, so you do not have to go to monthly follow-ups, and it saves time and effort, especially for orthodontic friends who travel long distances. Low friction light force orthodontics is a revolution in orthodontics, this technology is not just an alternative to the traditional ligature wire ligature ring fixed archwire method, but produces a physiological force close to the movement of teeth, while mobilizing and the body’s own dental bed reconstruction potential. The modern concept of orthodontics does not only focus on malocclusion but considers the dental alignment as a whole. The degree of tooth misalignment is no longer a measure of extraction, but rather the coordination of teeth and jaws and the body’s own growth and remodeling potential are the ultimate factors to be weighed. Low friction and light force orthodontics makes orthodontics not a step in the same direction but a light step.
