Abstract
In an orthodontic appliance, referred to as Herbst hinge, for the forward displacement of the lower jaw of a patient, with a pair of telescopes, each comprising a telescopic tube and a telescopic slide rod, which are attachable at their free ends in each case via a joint to the patient's upper jaw and lower jaw, respectively, for increasing the freedom of movement of the lower jaw while at the same time achieving the therapeutically desired forward push onto the lower jaw, it is proposed that the telescopes in the telescoped state be rigid, as known per se, but in the extended state be flexible.
