Establishing proximal contacts with pre-polymerized composite inserts

A technique of restoring Class II posterior restorations with resin-based composite and a pre-polymerized composite insert was presented. This technique is intended to aid the practitioner in obtaining tight, broad, proximal contacts without having to purchase special instruments or materials. This method is not time-consuming, nor technically difficult. Another benefit of this technique is that it reduces the total amount of volumetric shrinkage of restorative material inside the cavity preparation, as the composite insert is pre-polymerized before placement.
