Same great features as the 3D XR but with the added benefit of 3D Fusion Bands and 3D Fusion Wedges. Full curve, nonstick bands wrap further around the tooth, making ring placement easier. Both the Soft-Face 3D-Ring and the 3D XR ring adapt to the contours of the tooth to nearly eliminate flash. The 3D XR ring grabs the teeth to eliminate spring-off and is ideal for small, malpositioned teeth or between canines and premolars.
