Patent number: 4592729Abstract: The present invention refers to a strip-holder which is used in interdental therapy. The main object of the invention is to produce a strip-holder in which the abrasive steel-strip or the steel-sawblade, which is used for the reduction of the tooth width or for the abrading, cleaning and the prophylactic treatment of tooth and filling surfaces in the interdental space, can be easily and quickly inserted into the bow frame of the strip-holder and then tensed. The inventive strip-holder comprises a handle, a flat steel-bow or steel-frame and a gripping device, made of drawn-rod material, for the fixing and tensing of the steel-strip, which is inserted over the outer opening of the steel-bow into grip-slots. These slots are at the two opposite ends of the steel-bow and are cut at these ends into the rod material in such a way as to be slightly wider than the thickness of the steel-strips.Type: GrantFiled: March 29, 1985Date of Patent: June 3, 1986Inventor: Andrei S.
