Product information "SARA - Set" The SARA® is a fixed telescopic appliance with interchangeable external spring (3N/4N), which can provide an effective and patient cooperation independent therapy of class II cases without extraction or surgery.The basis of the development, in cooperation with Dr. Aladin Sabbgh, was a fusion between the Herbst hinge and Jasper jumper, with the aim of combining the advantages of these two techniques. The result is a force system with an external spring that can be universally integrated into any fixed bracket system. The attachment in the upper jaw is mesial, in which the Headgear bracket system can be integrated.
