Contoured Composi-Tight sectional matrix bands restore the natural, anatomical shape of teeth. The G-Ring tension provides tooth-separating force.
1. Matrix band is placed (Advanced Tip #1b) and wedged to seal the cervical margin (Figure 1). Pick a wedge size that firmly seals the cervical margin. The ring will provide tooth-separating force for a tight contact. It is not necessary to separate the teeth with the wedge, although some separation may occur.
2. Open and place G-Ring with Composi-Tight Ring Placement Forceps or rubber dam forceps (Figure 2). Grasp G-ring® at its outermost diameter. For an M.O. or D.O., use the G-Ring with the standard length tines. The long-tine G-Ring is used for M.O.D. and multiple-tooth restorations. Place the tines of the G-Ring between the band and the wedge (not on top of wedge), Figure 11. For restorations with wide embrasures, see Advanced Technique Tip # 3.
3. Matrix is burnished against the adjacent tooth (Figure 3).
4. Etch, disinfect, bond, apply composite resin and cure per the manufacturers instructions.
It is important to understand the basic technique for using the Composi-Tight Sectional Matrix System. For detailed instructions, please refer to the rest of our web site or call 888.437.0032.

 (Figure 2) G-Ring® is opened with GDS Ring Placement forceps or rubber dam clamp.
(Figure 3) Ring is placed between wedge and band for proper tooth separation. Matrix is burnish against adjacent tooth to create broad, tight contact. |
