FenderWedge Prep is a plastic wedge with an inbuilt steel plate specially designed for larger preparations such as crowns, veneers and inlays. FenderWedge Prep improves the quality of preparations and saves time thanks to increased vision and safety. FenderWedge Prep has a thin, “boat-shaped” tip which enables it to be inserted into tight proximal spaces at the same time as it compresses the gingiva without damage, avoiding bleeding and delay of impression taking. The steel plate is perforated thus allowing it to be bent before insertion to lean against the adjacent tooth, providing better access and vision. When rubber dam is not used, it is suggested to secure FenderWedge Prep with waxed floss.
