STRAIGHTENING SPRING INVISIBLE SIDE-WINDER

This version of the Side-Winder has a straight arm with a hook at a right angle at the end. This allows the arm to be almost parallel when it is hooked to appear invisible. The invisible Side-Winders are placed first and the elastomeric bonds then, allowing the elastomeric ring to retain both arc and spring. Placing the rings on the springs allows them to be easily replaceable without removing the springs at future appointments. Designed for use with Tip-Edge and Straight-Edge Brackets.
