Abstract
The purpose of this study was to determine the marginal fit of recasting by used nickel-chromium metal alloys, Hi-Crown, New-Crown and CB-80. Ninety crown prosthetics were divided into eighteen groups according to new to old metal ratios. Each crown was seated on its master die and then the marginal gaps were measured under optical microscope(
