Conservative Class II preps are great for saving tooth structure, but can make the placement of your Composi-Tight® sectional matrix bands difficult. FenderWedge® will lend you a hand by "pre-separating" the teeth while you prepare the tooth. When the prep is done, remove FenderWedge® and slide your Composi-Tight® band into place.
As a fantastic added bonus, the firm stainless steel shield protects the adjacent tooth from inadvertent contact with the bur. Again, protecting valuable natural tooth structure while saving you the hassle of having to polish out nicks.
