|
Self-ligating brackets do not require an elastic or wire ligature, but have an inbuilt mechanism that can be opened and closed to secure the archwire. In the overwhelming majority of designs, this mechanism is a metal face to the bracket slot that is opened and closed with an instrument or fingertip. About 13 new self-ligating brackets are commercially available until now. Self-ligating brackets offer the very valuable combination of extremely low friction and secure full bracket engagement and user-friendly. The core advantages of self-ligating systems offer the possibility of a significant reduction in average treatment times and maybe also in anchorage requirements, particularly in cases requiring large teeth movements. While further refinements about better treatment effectiveness, self-ligating system appear able to deliver measurable benefit with good robustness and ease of use. This article aims to outline the history and development of self-ligating brackets and put the current situation -the generic advantages and problems claimed for these brackets- in context. In addition we will discuss some typical self-ligating brackets, the Damon and SPEED bracket, shortly.
