‘Double Curve’ sectional bands are characterised by a higher curvature in the working area of the band compared to traditional Tor VM sectional matrix bands.

The additional curve allows the matrix band to span larger proximal gaps between teeth allowing excellent proximal contours to be developed where traditionally the band would require excessive burnishing.  These are also our "go to" for premolars and, in this video, we demonstrate their use, including wedge customisation and a ringless technique.

When selecting a wooden wedge, ensure that it seats horizontally and sits below the cavity margin.  If you find that the wedge might impede your band from seating, it can be customised with a bur.
