Clinical Case DO cavity on upper first molar

By Simon McDonald BDS

1 Pre-op of DO on upper first molar.

2 Completed cavity prep. Glass ionomer occlusal restoration was cut back and left as a base.

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.

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.

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

6 Occlusal view of the sectional matrix in place.

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.

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

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

10Finished restoration.

11Pre-op radiograph.

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