Jasper-Jumper

This is one of the many Herbst clones and is mechanically similar to the Herbst-Appliance. It consists of a plastic-covered spiral spring which clips onto the fixed brace and is used for the treatment of distal occlusion (Angle-Class II retrusive occlusion). Unfortunately, it often breaks and can cause problems in the fixed brace that the Jumper is attached to. Otherwise, it is generally a tried and tested and well-accepted treatment method. When used correctly, the treatment duration is shorter than it would be using a combination of the original Herbst-Appliance followed by an MB appliance (i.e. a fixed brace with brackets).
