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.
