[The clinical implication of self-ligating brackets].

The self-ligating bracket is a new kind of bracket. The cardinal feature of a self-ligating bracket is an inbuilt metal labial face to the bracket slot, which is referred to as a clip or slide. It reduces the chairside time and makes the ligating easier. The lower sliding resistance offered by self-ligating bracket reduces the resistance to close the space and makes the treatment more efficient.Low friction and low force are good for the alveolar bone rebuilding physiologically. The spring clip of self-ligating bracket can control the tooth in three dimentional directions as the conventional fixed appliances. Most orthodontists think that self-ligating bracket allows shorter treatment time and longer intervals and less visits. There is no significance difference between the debonding and ligating loss rate of self-ligating bracket and conventional bracket.
