The rings provide consistent separation force and are made of Nickel Titanium, ensuring a longer lifespan than stainless steel rings. The teeth of the rings contribute to excellent retention on the tooth. Rings and wedges can be overlapped and work well in complicated Class II restorations, such as those missing a cusp. The anatomical design of the wedges and wedge guards provides better sealing and tighter contacts. Contents: 20 matrices (5 x 45 mm, 15 x 55 mm), 15 wedges - 5 of each size: small, medium, large, 5 WedgeGuards (medium), 5 EZ anti-stick shields size 55 mm, 2 universal rings, 1 clamp, 1 pin clamp, and 1 sample of SDR (4 compules).
