Effect of recasting of nickel-chromium alloy on its porosity.

Statement Of Problem: As per the review of literature very few studies have been carried on recasting of dental casting alloy and in particlular its effect on occurrence of porosities.

Purpose Of Study: This study was designed to find out occurrence of porosities in new alloy and recasted alloy using a scanning electron microscope.

Materials And Methods: Different percentage combinations of new and once casted alloy were used to produce twenty five samples.

Effect of recasting of nickel: chromium alloy on its castability.

Castability plays an important role in selection of an alloy for cast dental restorations. This study was conducted to assess the effect of recasting of nickel-chromium alloy on its castability. Different percentage combinations of new and once casted alloy were used to produce a total of twentyfive cast samples using modified Whitlock's method and castings obtained from new alloy were used as control group.
