Long Span Restorations using Zirconia Frameworks by Azouzi, I Kalghoum, D Hadyaoui, B Harzallah and M Cherif in Modern Approaches in Dentistry and Oral Health Care in Lupine Publshers
Abstract
Porcelain fused to metal restorations have been considered as the
gold standard in prosthetic dentistry for a long time thanks to
their mechanical properties. However, several drawbacks (light
transmission blocked by the metal and the opaque porcelain, metal
corrosion phenomenon, gingival tattoo and potential allergic reactions)
have limited its use. Recently, all ceramic materials have been
introduced in prosthetic dentistry for the fabrication of natural like
crowns and fixed partial dentures using CAD/CAM techniques.
Zirconia seems to be of great interest thanks to its high esthetics and
mechanical characteristics. This article describes, through a clinical
report the use of Y-TZP based prostheses in long span fixed partial
denture to restore function and esthetics.
