Omni-Matrix Sectional bands conform to the natural anatomy of the tooth, while the clamp tines provide multiple contact points. The anatomical contour ensures the edge of the matrix will not catch on the gingival margin during placement. The retainer clamps stack easily, allowing both sides of the tooth to be held in a matrix at the same time. The retainer can be placed with any rubber dam forceps or sectional matrix forceps. The bands are interchangeable with all brands of sectional retainers.
