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.
