FenderWedge Assortment Kit 144/Bx. 36 wedges of each size. Designed to protect adjacent teeth during Class II preparation. Built-in 0.08mm thin stainless steel protective plate shields adjacent surfaces from bur contact. Besides protecting healthy tissue, its wedge component aids in separation for better access and, ultimately, an improved contact. FenderWedges press into tight interproximal spaces with ease and stay in place during the prep. Remove after prep and proceed with usual technique.
