CHARACTERISTICS OF METAL ALLOYS PROPERTIES FOR DENTAL CASTING AFTER THEIR REPEATED REMELTING

Area of Science:

• Dental Materials Science
• Biomaterials Engineering
• Metallurgy

Background:

• Repeated remelting of dental alloys can alter their physical, mechanical, and structural properties.
• Assessing the suitability of remelted alloys is crucial for ensuring the longevity and safety of dental prosthetics.

Purpose of the Study:

• To investigate the clinical and experimental viability of using remelted cobalt-chromium and nickel-chromium alloys for non-removable, one-piece prosthetics.
• To evaluate the properties of Remanium GM 700 and Remanium CSe alloys after multiple remelting cycles.

Main Methods:

• Experimental study involving sequential six-fold remelting of Remanium GM 700 and Remanium CSe dental alloys.
• Comprehensive analysis including chemical composition, metallography, microhardness, elasticity, and deformation testing.
• Comparison of remelted alloys with certified standards.

Main Results:

• Remelted Remanium GM 700 and Remanium CSe alloys exhibited chemical, physicochemical, and structural properties identical to certified alloys.
• Repeated remelting did not compromise the essential characteristics of the alloys for prosthetic applications.

Conclusions:

• Remelted Remanium GM 700 and Remanium CSe alloys meet the stringent requirements for materials used in the oral environment.
• These alloys, after up to six remelting cycles, are recommended for practical prosthetic dentistry due to their high quality and cost-effectiveness.
