No operative instrument kit would be complete without the Gingival Margin Trimmer Set. These versatile instruments are essential to create the axiopulpal bevel on class II amalgams, and to remove lips of undermined tooth structure at the gingival cavosurface margin. They are indispensable for creating bevels on inlays and onlays if held at the correct angle. GMT’s are used like a field plow, with the bevel resting on the tooth structure and the instrument pushed, rather than pulled to create the desired result – few dentists understand this principal. Other uses include sharpening line angles, and even placing retention grooves in class II amalgam preparations. Shipped in a factory-sealed protective case.
