The orientation of the band and the positive fit in the makes precise placement possible, even in posterior areas with tight access. Next, the gingival portion of the band is stabilised and sealed against the cavosurface margin of the preparation using the appropriate size XXX flexible wedge (Figure 6). The size of the XXX flexible wedge should be wide enough to hold the gingival portion of the matrix band sealed against the cavosurface of the preparation, while the opposite side of the wedge sits firmly against the adjacent tooth surface. To place the wedge, the XXX is bent to 90 degrees where the wedge meets the handle. The flexible wedge can now be placed with pressure conveniently, without the use of ** cotton forceps, ** that often times can be very clumsy. Once the wedge is in the correct orientation, a twist of the wand releases the wedge.
