FenderWedge PREP from Directa is a combined wedge and steel plate that protects the adjacent tooth and surrounding gingiva in all preparations such as crowns, veneers, and inlays.
A thin and “boat-shaped” tip allows it to be inserted into tight proximal spaces at the same time as it condenses the gingiva without damages. FenderWedge PREP can be inserted buccaly or lingually.
