First of all, from the design principle, self-locking braces are more advanced than traditional steel braces. Traditional steel braces use thin steel wires and rubber bands to exert pressure, so that the teeth gradually move to the correct position. Self-locking brackets are optimized and improved on the basis of traditional metal brackets, and locking devices are added. This locking device can make the brace self-correct and reduce the dependence on external ligature, thus simplifying the surgical process.
Compared with steel braces, self-locking braces are more comfortable to use. Since the self-locking bracket does not need to be fixed by ligating wires or rubber bands, the foreign body sensation in the oral cavity is reduced, and the irritation to the oral mucosa is reduced. In addition, the friction of self-locking brackets is also small, which makes teeth move more smoothly and reduces pain and discomfort.
In effect, both self-locking brackets and steel brackets can achieve the purpose of correcting teeth, but self-locking brackets have some unique advantages. For example, self-locking braces can control the movement of teeth more accurately and improve the accuracy of correction. In addition, due to the small friction of the self-locking bracket, the closing time of the tooth extraction gap can be shortened, thus shortening the whole correction cycle.
In addition to the above differences, self-locking braces and steel braces are also different in price and maintenance. Generally speaking, the price of self-locking brackets is higher than that of traditional steel brackets, mainly because the design of self-locking brackets is more complicated and the manufacturing cost is higher. In terms of maintenance, self-locking brackets need to be cleaned and maintained more carefully because of their special design to prevent food residues and bacteria from breeding in the mouth.
Generally speaking, self-locking brackets and steel brackets have their own advantages and applicability in orthodontics. The choice of braces mainly depends on the individual's dental condition, orthodontic demand and economic ability. If you are looking for a more comfortable and efficient orthodontic experience, and economic conditions permit, self-locking braces may be a good choice. However, if you are sensitive to price or have simple dental conditions, traditional steel braces are also an economical and effective choice.
Finally, it should be emphasized that no matter which braces are selected, they need to be carried out under the guidance of a professional doctor. The doctor will make a suitable orthodontic plan for you according to your dental condition and orthodontic needs, and provide you with necessary guidance and help during the whole orthodontic process.
