RNC contains silica, zirconia and agglomerated nano-sized particles of silica and zirconia embedded in a cross-linked polymer matrix. One of its advantages is quality similar to glass ceramics. Another possible advantage is the wear rate of this resilient ceramic approaches the wear rate of adhesive resin cement, which means margin integrity might be better maintained over time. It was also noted that due to differences in its elastic properties, RNC is less brittle, less prone to fracture, and more flexible than glass ceramics. Its greater resilience was attributed to its ability to accommodate more stress absorption by way of deformation.
