Abstract:
A matrix band holder includes contour surfaces on the clamphead corresponding to a pre-contoured matrix band so that the concave shape of the band is maintained as it is tightened against the tooth. The clamp further includes a tethered outward-tension horseshoe-shaped spring with downward-facing perpendicular ends that force the band into contact with adjacent teeth, thus facilitating tight proximal contact of dental restorations.
