Direct from the Operatory: Class II Restoration with ACTIVA BioACTIVE-RESTORATIVE

By: Dr. Jack Griffin

The patient presented with interproximal decay between the bicuspid and molar (Figure 1) and needed Class II restorations on both teeth.

Figure 1. Shows interproximal decay between the bicuspid and molar.

Using an Isolite system to ensure proper isolation, I placed wedges before drilling. This technique creates pressure on the PDL, helping to protect the gingiva while also making it easier to place a sectional matrix. I placed a caries indicator to make decay removal more efficient by staining debris, denatured collagen, decalcification, and decay.

Afterwards I removed the pre-operative wedges, placed a sectional matrix and a separating ring (Figure 2). A total etch with 37% phosphoric acid was done for 15 seconds, rinsed thoroughly and a universal bonding agent placed predominantly on the enamel. The restoration was bulk filled using ACTIVA BioACTIVE-RESTORATIVE (Figure 3) and then light cured from the lingual, buccal and then occlusal sides.

After curing, I removed the matrix materials and contoured the restoration with a round bur, light pressure, and water. The occlusion was checked and adjusted before smoothing and polishing the moist tooth with a rubber composite polishing cup. The final restoration meets the aesthetic demands of the patient while providing the ionic exchange to combat long-term restoration failure.
