3D Fusion Wedges combine two materials to create the perfect blend of adaptability and retention. Superior adaptability: The Soft-Face™ outer cover of 3DFusion allows it to do what no other wedge can: truly adapt to interproximal irregularities. No more dislodging: The soft retention fins bend down during wedge insertion and then spring back when out of the interproximal space. Wedges dislodging from their position is a thing of the past. Perfect for any matrix: No matter what your preferred matrix system is, these ultra-adaptive wedges will help you create predictable and high-quality restorations.
