ABSTRACT:
A tension applying mechanism is disclosed for operative interposition between an end of an orthodontic facebow and an adjacent end of a headstrap for holding the facebow. The mechanism includes a body securable to the adjacent end of the headstrap, an elongated strap held by the body, and indications along at least one of the longitudinal edges of the strap. The strap has a plurality of holes spaced from each other in a direction of elongation of the strap. The indications help a user distinguish one hole from the other to enable recognition of which hole the end of the orthodontic facebow is to be inserted. The indications are spaced from each other in correspondence with at least some of the holes. The indications are physically different in configuration from the longitudinal edges and may be projections or notches.
