Dentistry instrument for measuring, setting and pre-cutting the endodontic canal equipment and for measuring, dividing up and pre-cutting the canal closure cones

摘要

Dentistry instrument. It consists of two plates (1 and 2) which are integral with handles (5) equipped with rings (6). They are applied and pressed against one another by an elastic device (3) and can turn in opposite directions around a central hinge pin (4). A recess (19) formed in the elastic device (3) is combined with notches (14 and 15) on the outer face of the plate (2) in order to contribute to forming an apparatus for measuring length. Holes (10 and 13) calibrated in diameter and drilled in the plates (1 and 2) permit, by shearing, the clean cutting of the sealing cones. The elements (8 and 9) of a press which are mounted on the handles (5) permit, by being brought together and by their pressure, the canal instruments to be curved. Wedge-shaped jaws (7) which are equipped with a notch permit the pre-cutting of the sealing cones. IMAGE
