Extra-oral traction (E.O.T.) to a facebow is used with many types of removable, functional, and fixed orthodontic appliances. A versatile and popular method involves the elastic force being provided by an Interlandi headgear. The facebow, which is of necessity removable, can be displaced from its intra-oral attachments (whilst still connected to the headgear by the elastics) and may result in personal injury. This paper describes a suitable simply made device that can be incorporated to prevent facebow dislodgement, thereby improving safety.
