  • Alumina Vs Zirconium Oxide: A Comparative Wear

    To evaluate zirconium oxide wear resistance in a ceramic-ceramic coupling, a “ring on disk test” was performed. The results (medium print deepness: 16 mm 3 /h for zirconium oxide vs 0.0033 mm 3 /h for alumina oxide) make the zirconium oxide unsuitable for the use in clinical application as ceramic-ceramic coupling surface.
