What is the difference between self-locking brackets and metal brackets?

The differences between self-locking brackets and metal brackets are: different fixing methods, different correction time and different follow-up intervals.

First, the fixed difference.

1. Self-locking bracket: increase the freedom of the arch wire of the self-locking bracket in the groove and reduce the friction.

2, metal brackets: metal brackets need to be fixed with thin steel wire or ligature ring and arch wire, which is easy to cause soft tissue damage.

Second, the correction time is different.

1. Self-locking bracket: Self-locking bracket has a short period.

2. Metal brackets: It takes a long time to correct metal brackets.

Third, the interval between follow-up visits is different.

1. Self-ligating bracket: The follow-up interval of self-ligating bracket is generally 8 weeks.

2. Metal brackets: The interval between metal brackets and follow-up visits is about 4 weeks.
