A complete, high-quality, 5-component sectional matrix system designed to achieve accurate Class II composite restorations with smooth contours every time. Universal ring made from a proprietary resin material that is autoclavable up to 5 times. Exceptional strength for optimal separation force, and stability to deliver perfect, tight interproximal contacts. Unlike Tofflemire retainers that are difficult to position, leave poor contacts, and cause patient discomfort, the X5 Sectional Matrix System is affordable and easy to use. Essential Kit includes Matrix Rings Grey x 10, Wedges x 75 (Small, Medium, Large), and Matrix x 100 (3.5mm, 4.5mm, 5.5mm, 6.5mm).
