Articulating foil for use in a wide variety of clinical situations, including wet or dry teeth, limited opening, limited vestibular space, gaggers, and metal and non-metallic restorations. Allows the user to verify occlusal contacts for both arches from one tooth to an entire quadrant, using the mini or the original quadrant size. Double-sided foil is only 8 microns thick and is able to mark wet surfaces, dry surfaces or highly polished surfaces, such as cast gold or porcelain. Mounted in its own frame: no forceps needed.
