In this short video from 3M, you can see what a self-ligating bracket is. There is much debate about the merits of self-ligating brackets and whether they offer faster or more comfortable orthodontic treatment but from a patient perspective, the brackets can appear to be smaller as they do not require the elastic ligatures to hold the archwire¬†in the bracket. It is well known that elastic can easily stain so self-ligating brackets remove this issue however if you require an elastic power-chain for space closure, this problem won’t go away.
