New clinical applications for the Jasper Jumper.

This article describes the use of the Jasper Jumper in the treatment of class III anomalies, both theoretically and with a case report. Contrary to its use in class II anomalies, the Jasper Jumper is fixed to the 6-year-molars in the lower jaw and in the canine area in the upper jaw. This results in a continuously working mechanism--independent of co-operation on the part of the patient.
