Zirconia, un material extraordinar
Madalina CAZAN, Valentina DINCA, Maria DINESCU and Cristian Radu POPESCU
ABSTRACT
Titanium is a valuable biomaterial for implantology since 1952 and demonstrated its impressive clinical steadiness over time, but some studies also showed to be the cause of significant local reactions and chronic pain that may require its removal. Nowadays zirconia replaced titanium more often in orthopaedic and dental surgery because of its higher flexure strength and fracture resilience. Perhaps zirconia ceramics (zirconium oxide partially stabilized with yttrium) is the best solution for titanium failure. This work is a review as well as an overview of zirconia and its applications.
