Directa Dental AB' s FenderWedge is a combined wedge and protective stainless steel plate that prevents any contact between bur and tooth during preparation of teeth for class II fillings and other similar procedures.
The wedge is easily inserted from the side, not through the contact point, which helps to ease the teeth apart before the insertion of a matrix. The disposable wedge comes in 4 different widths and can be placed before preparation for a better contact surface.
