Zirconia based restorations are fast becoming the most popular restorations because of their optimum esthetics, strength and biocompatibility. Zirconia restorations eliminate the need for unappealing metal which mean tooth restorations have better translucency and color similar to that of natural teeth. It is stronger than traditional all porcelain restoration which means that its more fracture resistant. Polished zirconia also has the least plaque retention therefore possibly helps reduce the risk of recurrent decay around the margins of restorations.
