Area of Science:

  • Materials Science
  • Dental Materials Science
  • Surface Chemistry

Context:

  • Investigating the interface between Wiron 99 (Bego) dental nickel-chromium (Ni-Cr) alloy and Vision (Wohlwend AG) ceramic opaquer.
  • Utilizing Scanning Electron Microscopy (SEM) to analyze the microstructural and chemical composition at the metal-ceramic junction.

Purpose:

  • To elucidate the formation and role of intermediate phases at the metal-ceramic interface.
  • To understand the chemical diffusion and selective affinity of nickel (Ni) and chromium (Cr) between the dental alloy and ceramic opaquer.

Summary:

  • Solid-phase reactions at the interface form intermediate phases essential for metal-ceramic bonding.
  • Analytical methods revealed non-monotonous concentration gradients for Ni and Cr across the interface.
