Abstract

A simple and safe extraoral traction model is described. This consists of a face-bow with activated outer arms and a neck strap or headgear without any elastic force, such as rubber bands, elastic ribbons, coil springs, etc. The appliance cannot be withdrawn from the mouth by acident; therefore, the patient is protected from possible injuries.
