DO Cavity on Upper First Molar by Dr Simon McDonald

Clinical Case
DO cavity on upper first molar
By Dr Simon McDonald

1
Pre-op of DO on upper first molar.

2
Completed cavity prep. Glass ionomerocclusal 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 V3 Tab-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 wiggle 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.

10
Finished restoration.

11
Pre-op radiograph.

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