Zirconia - a boon to prosthodontics
Journal Title: IP Annals of Prosthodontics and Restorative Dentistry - Year 2016, Vol 2, Issue 3
Abstract
With the expansion of porcelain-fused to- metal (PFM) procedures in the early sixties, metal–ceramic restorations have represented the “gold standard” for prosthetic dentistry, because of their good mechanical properties and quite pleasing esthetic results, along with an acceptable quality of their marginal and internal adaptation. The polycrystalline zirconium dioxide (zirconia) resulted valuable in prosthodontics, due to its exceptional mechanical properties and improved esthetics compared to metal–ceramics1 . Zirconia is a ceramic material technically and an oxide chemically2 , insoluble in water and non-cytotoxic3 . Studies, both in vitro and in vivo, showed its low adhesion to bacteria, even lower than on titanium4 and favorable radio-opacity and a low corrosion potential1
