In orthodontics, what is the difference between self-ligating and non-self-ligating brackets?
Self-ligating brackets have their own locks. If braces require an archwire, we can use the locks on the self-ligating brackets to lock the archwires. Non-self-ligating brackets do not have locks to hold the small archwires. If it gets stuck, it must be tied with a very small stainless steel ligature wire to tie the arch wire.
Therefore, in non-self-ligating brackets, there is a possibility that the small ligature wire will pierce the oral mucosa and gums. This possibility does not exist in self-ligating brackets, so the comfort of self-ligating brackets will be better than that of self-ligating brackets.
The second is that the correction force of self-ligating brackets is relatively gentle and continuous, and the friction is relatively low. Therefore, when self-ligating brackets are reviewed, the time interval is generally about one and a half to two months, compared with non-self-ligating brackets. The follow-up time is about one month.
In terms of orthodontic function, self-ligating brackets have a certain expansion effect during the correction period; compared with non-self-ligating brackets, doctors generally change the procedures more quickly with self-ligating brackets, which can save doctors time in dealing with patients. , the time of patient’s treatment.
