Super-elastic Coil Springs, developed along with SENTALLOY® arch-wires, are now an indispensable item for orthodontic treatments. Thanks to these, orthodontists are increasingly using sliding mechanics in which teeth are moved laterally along arch-wires, and as well the remarkable performance of our COIL SPRINGS has been objectively appraised in academic treatises. We have a wide variety of these springs such as open coils, closed coils with hooks on both ends, stop-wound coils, and closed coils with ligature-wire on one end.
