V4 ClearMetal Matrix System
ClearMetal is the only transparent matrix with the advantages of metal malleability. Hundreds of microscopic resin-filled windows allow light to pass through the stainless steel, so composite in a Class 2 restoration can be cured laterally, interproximally, and occlusally, while leaving no imprint on the composite. The V4 System easily creates natural contours and the added benefit of ring, matrix, and wedge transparency makes it an excellent match for bulk fill resins and deep cavities. A feature of the ClearMetal Matrix is that the micro-windows act like a "ramp cure", where light intensity is increased gradually to reduce initial stress and optimize polymerization. When the matrix has been removed, the composite can be given a final cure.
Stepping into the Matrix
As a result of the complexities involved with the placement of composite resin in the posterior dentition, developments in matrix system technology have emerged, such as improvements in matrix design and interdental separation techniques. These innovations have allowed the dentist to achieve the most advantageous proximal contact surfaces and anatomically correct contours—so important for optimum form and function of the dentition as well as for stimulation and protection of the periodontal complex. - Owens B, Phebus J.
