A unique combination of a preparation shield and a sectional matrix for Class II fillings of primary teeth. FenderPrime enables a fast, simple and safe restoration of primary teeth. FenderPrime is a plastic wedge with a steel plate, which is inserted into the proximal space. The 'boat-shape' of the tip allows the gingiva to be condensed without damages and reduces the risk for bleeding. Before filling the wedge and plate can be bent to adopt the contour of the tooth. If needed it can easily be secured with a floss.
