Treatment of Mandibular Retrognathism with the Herbst Appliance
نویسنده
چکیده
The first attempt at stimulating growth of the mandible in therapy of distal bite Class II/1 was initiated by Kingsley in 1877. The method described as “jumping the bite” is still applied today according to the principle of functional bimaxillary appliances such as for example activator, bionator, function regulator (1-3) and others, whereby the mandible is brought into the anterior position by constructive bite, inciting remodelling in the area of the jaw joints.
