Area of Science:

  • Materials Science
  • Biomaterials Engineering
  • Ceramic Engineering

Background:

  • Yttria-stabilized zirconia (5Y-PSZ) is a widely used dental ceramic.
  • Improving the mechanical reliability and strength of 5Y-PSZ is crucial for dental applications.
  • Surface defects and microstructural inconsistencies can compromise the performance of zirconia restorations.

Purpose of the Study:

  • To develop a thermally compatible glass for infiltration into 5Y-PSZ.
  • To characterize the developed glass and its interaction with 5Y-PSZ.
  • To evaluate the structural reliability and mechanical behavior of glass-infiltrated 5Y-PSZ.

Main Methods:

  • Synthesis of a novel glass via the sol-gel method.
  • Application of glass gel to polished 5Y-PSZ discs (1.5mm x 15mm).
  • Mechanical testing (biaxial flexural strength, ISO 6872:2015), Weibull analysis, X-Ray Diffractometry (XRD), Scanning Electron Microscopy (SEM), and fractographic analysis.

Main Results:

  • Glass infiltration into 5Y-PSZ (Zinf-tens and Zinf-comp groups) significantly increased characteristic strength compared to control (Zctrl).
  • Zinf-tens group exhibited highest characteristic strength (824 MPa, m=9.9), followed by Zinf-comp (613 MPa, m=10.2), and Zctrl (534 MPa, m=8).
  • XRD revealed 20-50 μm infiltration depth, yttrium dissolution, cubic grain size reduction, and internal failure origins in the Zinf-tens group.

Conclusions:

  • The developed glass is thermally compatible with 5Y-PSZ.
  • Glass infiltration enhances the characteristic strength and structural homogeneity of 5Y-PSZ.
  • Infiltration reduces surface defects and modifies the failure mode, improving overall mechanical reliability.
