Abstract

Various factors are responsible for the success of a Ni-Cr prosthesis. Marginal fit or Integrity is one. The close adaptation of the margin of the prosthesis with the finish line of preparation leads to good Marginal Integrity This study compares the marginal integrity between an imported Ni-Cr alloy and an indigenous Ni-Cr alloy.

There is no significant difference in mean values of vertical marginal opening between Indigenously and Imported alloy at “As-cast-fit” stage.

The mean value of vertical marginal openings of both alloys after opaque, Body-enamel and Glaze firings are comparable (No significant difference).
