The Distal Jet appliance is a popular distalization appliance that uses NiTi coil springs and an adjustable locking mechanism to distalize teeth. The nance button provides anchorage. The spring mechanism is close to the center of molar rotation, ensuring more bodily movement of the molars during treatment.
Spring Activated Distalizer
Spring Activated Distalizer–A MidLyne innovation, this distalizer incorporates a nance button for anchorage. Bilateral, sistered rod and tube mechanisms use NiTi coil springs to provide light, continuous forces for distalization. A fixed appliance, it requires no compliance from the patient and therefore has predictable results.
