DESCRIPTION
The V3 Ring has the widest indications for use of any sectional matrix ring. The only nickel-titanium ring, the V3 ensures optimal separation forces to produce perfect, tight contacts and an anatomically correct Class II composite restoration.TRANSCRIPT

1 Completed cavity ready for restoration.

2 Triodent matrices, Wedges and V3 Rings have been placed to create sound contact points. Enamel margins are selectively etched with 37% phosphoric acid gel for 15 seconds and rinsed.

3 The dentin is conditioned with 10% polyacrylic acid for 10 seconds, rinsed and gently dried.

4 Fuji IX Xtra is carefully injected into the depths of the cavity and manipulated on to the dentin using a very small micro-brush dipped in Fuji Lining. The Fuji Lining is polymerized for 10 seconds.

5 GBond (self-etching resin bonding agent) is liberally applied to the etched enamel and GIC surfaces for 10-15 seconds. Any dentin that was not covered by the GIC is also effectively bonded at this stage with the GBond. The GBond is then vigorously air-thinned until there is no movement in the bonding layer before polymerizing.

6 A thin layer of radio-opaque flowable is placed over all internal surfaces and polymerized.

7 Using the 0.5 C-Factor concept, Gradia Direct was then used in incremental layers to build up the restoration.

8 Completed restoration build-up.

9 V3 Rings and matrices removed. There is a film of bonding agent on the tooth and some thin flash in the region of the marginal ridges that required minimal effort to finish off.
