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.

1. Clinical Case DO cavity on upper first molar By Simon McDonald BDS

2. 1 Pre-op of DO on upper first molar.

3. 2 Completed cavity prep. Glass ionomerocclusal restoration was cut back and left as a base.

4. 3 Tab of V3 Tab-Matrix was bent mesially to give the advantage of a "contra-angle". Tab was then folded over on to the adjacent tooth.

5. 4 Tab of the matrix was trapped against adjacent tooth with a finger to prevent it from moving while placing the pink (medium) Wave-Wedge.

6. 5 Universal V3 Ring in place over the Wave-Wedge. Finger placement stabilized the V3 Tab-Matrix and ring while forceps were disengaged.

7. 6 Occlusal view of the sectional matrix in place.

8. 7 V3 Tab-Matrix wings were peeled away from the composite to de-bond the matrix. Side-hole in matrix gripped with Pin-Tweezers to wriggle matrix out.

9. 8 Buccal view of proximal contour after V3 Tab-Matrix removal, prior to any finishing. Note the marginal ridge form and lack of flash.

10. 9 Trimming was done using a diamond bur with no water. White area was the only region that needed finishing.

11. 10 Finished restoration.

12. 11 Pre-op radiograph.

13. 12 Post-op radiograph. No interproximal finishing was required.
