3 rings (short, tall & wide prep).
Same great features as the 3D XR but with the added benefit of 3D Fusion Bands and 3D Fusion Wedges. Superior tooth separation force through advanced engineering and material selection. Soft-Face silicone ring tips with enhanced marginal ridge anatomy hug the pre-contoured dead-soft matrices to the tooth for flash free, contoured restorations. Composi-Tight® 3D Fusion features easy ring stacking, over-the-wedge placement and Ultra-Grip anti-ring slip extensions.
