Description

The Piggy Back Spring is a clampable pressure spring element, which is inserted safe and easy. In the levelling phase, pressure on the crowded teeth is often already required. In spite of brackets, the piggy back spring can be mounted here in seconds without removing the treatment arch. Just squeeze the hooks and the job is done. This makes possible simultaneous use of brackets in the crowded area. Six different lengths allow space to be gained from a single tooth area to eye tooth to eye tooth distance. The individual sizes are arranged in different colours. With full compression approximately 200 cN force expansion (progressively reducing). Spring is in elgiloy alloy and the hooks are stainless steel.
