Texas Tip: Matrix Band Gaps

Texas Tip: Matrix Band Gaps

This month’s Texas Tip was written by Texas Center co-founder, Dr. Hal Stewart

It can be frustrating when doing an MO, MOD, DO composite and you cannot get the matrix band sealed completely at the gingival box. To proceed with a gap at the gingival box would result in an overhang. Here is a very quick and easy way to solve this problem and save a lot of time.

  1. Place band and wedge, if there is a gap (figure 1) then:
  2. Take a small cotton or sponge pellet
  3. Soak in your adhesive
  4. Wedge in on the non-prep side of the band, pushing the band in and closing the gap (figure 2)
  5. Cure
  6. Proceed with your composite
