Abstract

This in vitro study compared various peripheral shelves (steps) as resistance features for complex amalgam restorations. Three different sizes of peripheral shelves were evaluated: 1 mm x 1 mm, 2 mm x 2 mm, and 1 mm cervically x 2 mm pulpally. The resistance of these features was compared to a control group that utilized two amalgam pins. The 1 mm x 1 mm shelf provided significantly less resistance than the other groups.
