1. Clinical Case Fractured MOL By Dr Simon McDonald

2. 1 Pre-op with fractured MOL composite.

3. 2 A purple (large) Wave-Wedge was placed interproximally to depress the rubber dam and gingival tissues. The wedge was lubricated to allow it to slide in.

4. 3 Completed preparation. Note that original restoration extended lingually and this created a wide embrasure.

5. 4 A 5.5mm V3 Tab-Matrix was placed without removing the Wave-Wedge, which acts as a guide for the matrix and also avoids entrapment of gingival tissue between the matrix and the tooth.

6. 5 Narrow V3 Ring was placed. Note how the ring did not collapse into the cavity on the lingual side.

7. 6 Cured composite resin prior to matrix removal. The composite in this case was Gradia Direct P-NT from GC.

8. 7 Occlusal view of the restoration immediately after matrix removal. Note the lack of flash.

9. 8 Buccal view of the restoration immediately after matrix removal.

10. 9 Occlusal view of the completed restoration.

11. 10 Lingual view of the completed restoration.

12. 11 Final image after the rubber dam was removed.

13. 12 Post-op radiograph.
