ZrAdvance
All Zirconia Crowns & Bridges.
ZrAdvance™ all zirconia crowns and bridges were introduced in 2010. It is our own monolithic restoration which has proved to be very popular around the UK, providing an all ceramic alternative to full cast or metal occlusal crowns which is still strong enough to resist forces applied by bruxers and grinders who might well have destroyed other restorations.
ZrAdvance™ is made from a zirconia that is 15-25% more translucent than the standard material and is ideal for heavy bites in the posterior region.

The Material
ZrAdvance™ is made from a high translucency Zirconia. There are two main factors affecting the translucency of Zirconia:
i. grain size and structure – the smaller and more homogenous the particles are, the greater the translucency.
ii. Aluminium oxide – the less Alo2 in the Zirconia the better the translucency. However, Alo2 is responsible for aging resistance, so really we need to keep it.
ZrAdvance™ uses high quality Zirconia with certain refinements to the grain size and crystal structure. This maintains the high flexural strength and also maintains its aging resistance while increasing the translucency by around a further 20%.
