Self-locking.

Self-locking is expensive. If you choose metal self-locking, the price of private dental clinics starts at 1.5W, and public hospitals basically start at 20,000. Movable wing dental braces cost about 8,000 to 11,000 yuan.

Self-ligating brackets exert strong force on teeth, accelerate the renewal and arrangement of gum cells, and achieve rapid correction effect. It is necessary to go to a qualified plastic surgery medical institution for the operation, which will help improve the safety factor. During braces correction, chew less hard food to avoid causing braces to break and affect the later correction effect.
