zirconia ceramic



Zirconia (ZrO2) is a ceramic material with adequate mechanical properties for manufacturing of healthcare devices. Zirconia stabilized with Y2O3 has the most effective properties for these applications. When a stress occurs on a ZrO2 surface, a crystalline modification opposes the propagation of cracks. Compression resistance of ZrO2 is about 2000 MPa. Orthopedic investigation led to this material getting proposed for the manufacture of hip head prostheses. Prior to this, zirconia biocompatibility had been studied in vivo; no adverse responses have been reported following the insertion of ZrO2 samples into bone or muscle. In vitro experimentation showed absence of mutations and great viability of cells cultured on this material. Zirconia cores for fixed partial dentures (FPD) on anterior and posterior teeth and on implants are now obtainable. Clinical evaluation of abutments and periodontal tissue should be performed prior to their use. Zirconia opacity is quite beneficial in adverse clinical conditions, one example is, for masking of dischromic abutment teeth. Radiopacity can aid evaluation throughout radiographic controls. Zirconia frameworks are realized by using computer-aided design/manufacturing (CAD/CAM) technology. Cementation of Zr-ceramic restorations is often performed with adhesive luting. Mechanical properties of zirconium oxide FPDs have proved superior to these of other metal-free restorations. Clinical evaluations, which happen to be ongoing for 3 years, indicate a very good success price for zirconia FPDs. Zirconia implant abutments also can be applied to enhance the aesthetic outcome of implant-supported rehabilitations. Newly proposed zirconia implants seem to have excellent biological and mechanical properties; additional studies are needed to validate their application.
