The tiny rubber band that fits around your bracket to hold the archwire in place. They come in a variety of colors.
Headgear uses an external wire apparatus known as a facebow to guide the growth of your face and jaw gently by moving your teeth into proper position. The force is applied to the facebow by a spring-loaded neck strap or head strap. The straps have a safety release that disconnects if the facebow is pulled or snagged.
