Nanosilver-Reinforced AgSn Alloys for Dental Applications: Mechanical Behavior and Hardness

Page: [77 - 81] Pages: 5

  • * (Excluding Mailing and Handling)

Abstract

Aim: AgSn alloys of different compositions were prepared by direct mixing with silver nanoparticles, and synthesized, in turn, by an environmentally friendly method.

Methods: The procedure was carried out by following the standard technique for preparing dental materials and devices. A detailed mechanical characterization, including the maximum elongation at break, the ultimate tensile strength and the hardness of the resulting nanocomposites, was obtained and numerically fitted by statistically significant equations.

Results: The results showed improved mechanical performance, as compared to standard materials used in dentistry, in particular, amalgams.

Conclusion: The procedure described allows to produce low-cost materials with tailored mechanical properties.

Keywords: cast alloys, AgSn amalgams, silver nanoparticles
