Dentatus Nyström Matrix RetainersDescriptionThe Dentatus Nystrom Matrix Retainers are available in three different models:‐ Models MEC‐N1 and MEC‐N2 hold the matrix bands at slight, opposite angles. They are markedrespectively with one vertical line and two vertical lines. Figure 1 shows which model is used forwhich quadrant in the mouth. The angled slot makes the placement and holding of the matrix bandeasier and helps avoiding distortion of the band.‐ Model MEC holds the matrix band straight and may be used for any quadrant of the mouth.Placement of the retainer may be bucal (recommended) and lingual (only recommended duringrestoration of the buccal wall) (Figure 1).Figure 1
