Chemical and Electrolytic Polishing of Ni-Cr Alloy for Dental Use

The effect of recasting on biological properties of Ni-Cr dental alloy

Aleksandra ČAIROVIĆ Faculty of Dental Medicine University of Belgrade Clinic for Prosthodontics Rankeova 4, 11000 Belgrade Serbia [email protected] SUMMARY Introduction Increases in market prices of gold over the last 20 years have led to expansion of basic dental alloys, which, primarily due to their good mechanical properties and acceptable prices, have found their place in everyday...

Dental casting of superelastic Ni-Ti alloy.

Rods of Ni-43.5wt% Ti alloy were prepared under various casting conditions. Specimens which were melted in a cordierite crucible and cast in a phosphate-bonded investment mold had less strength and elongation than those melted in a copper crucible and cast in a phosphate-bonded investment mold. All castings exhibited superelasticity at room temperature. The upper limit of recoverable strain was...

Laser Welded Ni-Cr Dental Alloys Inspection

Minor problems arising from optimizations by welding of fixed prostheses frameworks can be identified by macroscopic and microscopic visual inspection. The purpose of this study was to highlight the visible discontinuities present in the laser welds of dental Ni-Cr alloys. Ni-Cr base metal alloys designated for fixed prostheses manufacture were selected for the experiments. Using cast plates, p...
