Pre-operative appearance of Tooth No. 13 MOD showing a fracture of the amalgam restoration at the disto-buccal corner of the restoration. The patient has been anesthetized with one carpule of 2% Xylocaine with 1:100,00o epinephrine, and a rubber dam has been placed using a sling technique.
The existing amalgam has been removed and the preparation has been refined to remove any caries or stain. The Palodent® Plus Sectional Matrix System is in-place demonstrating one of the possible ways the rings can be positioned to allow for restoration of a MOD posterior composite.
After etching of the enamel margins for up to 30-seconds, scrubbing in Prime&Bond Elect® Universal Dental Adhesive followed by a 10-second light cure, the first restorative layer is placed using SureFil® SDR® flow Posterior Bulk Fill Flowable Base up to 4mm. Care is taken to allow room for a 2mm layer of hybrid composite to be placed over the SureFil® SDR® flow.
After light curing the SureFil® SDR® flow for 20-seconds, the final restorative layer is placed using TPH Spectra® Universal Composite Restorative shade A2. After sculpting and manipulating the TPH Spectra®, it is light cured for 20-seconds.
The final composite restoration on Tooth No. 13. The rubber dam has been removed; the restoration has been smoothed with fluted composite burs, and finished with the Enhance® Finishing System. Note the broad contact between Tooth No. 13 and the adjacent teeth.
