The secret to SPEED's precision control is SPEED's Super-Elastic Spring-Clip. Once deflected, the spring-clip works relentlessly to reposition the tooth relative to the archwire. The intimate relationship between the archwire and spring-clip provides unparalleled control of rotation, tip, and torque.

Additionally, SPEED's spring never tires or degrades like conventional ligatures. As a result, the range of appliance activation is extended, reducing both patient visits, and treatment time.
The above visual, taken from Dr. Hanson's 1983 Great Lakes Society presentation, shows how elastomeric donuts degrade during a single treatment appointment.
