What is the difference between self-locking brackets and ordinary brackets? Which is better?

Ordinary brackets need to be ligated, which has great friction with dental arch wires. The self-ligating bracket does not need to be ligated, which saves the time beside the chair, and at the same time, the friction is small, the correction force is light, and the patient feels comfortable. The most obvious advantage of 3B Weipai self-locking is that the self-locking bracket is free from ligation and has no friction resistance of traditional brackets, so the total course of treatment can be shortened by 1 ~ 4 months. This is also the attractive charm of self-locking brackets.
