Abstract
A pivot for use in a Herbst orthodontic appliance has a base attached to the attachment structure on a patient's tooth, a barrel extending from the base to pass through an eyelet on the end of telescoping members of the Herbst appliance, and a head retaining the eyelet on the barrel. The barrel includes a saddle that allows a range of angular motion for the telescoping members outside of a plane normal to the central axis of the barrel.
