T BAND MATRIX BAND

Use of the T Matrix Band

1. With the No. 110 pliers, bend the flanges of the "T" upward (Fig. 15-26, A). Use a mirror handle or the handle of the pliers to form a circle.

2. Fold the T-wings over the circle formed. The wings should be loose enough for a sliding joint. Adjust the band so it is approximately smaller than the tooth to be restored (Fig. 15-26B). Place the matrix on the tooth with the folded joint on the buccal side of the tooth.

3. Hold the band with one finger. Pull the tab tight with No. 110 pliers or your finger. Fold the tab back over the joint (Fig. 15-27).

4. Remove the band. Flatten the join with No.110 pliers. Replace the band on the tooth. Wedge tightly.

5. When the restorative procedure is finished, remove the band by raising the tab over the joint and loosening the T part of the bands (Fig. 15-28). Remove the wedge. Slide the band occlusally through the contact.
