We have great news. ROE, like many other dental labs across the country, has transitioned away from a previous zirconia option and introduced our own superior monolithic zirconia brand, called zRc. While offering the same price point, we’ve been able to deliver a product that is stronger, more translucent, offers a longer warranty, and is guaranteed to exceed what you’ve come to expect from ROE:

  • Better aesthetics (higher 4Y translucency) resulting in a more beautiful finished product
  • Increased warranty term (8 years) providing greater confidence
  • Zero white spot issues resulting from adjusting as zRc is made from multi-colored solid blocks

This combination of benefits and price makes changing to zRc a no-brainer for us and our clients.

Evolution of Zirconia

Nearly all big labs in the US have moved away from out dated zirconia materials due to the evolution of superior zirconia materials. Zirconia has evolved tremendously in the last decade and manufacturers have created better formulas that offer higher light transmission, better wearability, higher strength, and other superior properties.

zRc is the latest in the 4Y class of zirconia which means it has a 5% higher translucency. It’s also made domestically! zRc is one of the cutting edge of materials we are transitioning to here at ROE. We also offer an alternative to the previous outdated Anteriors called zRc -A.

The “Mole Percent” of yttria in Zirconia explained

Paul Cascone, BE MetE, MS describes the classifications used to describe yttria present in the zirconia. Most companies provide a weight percent of zirconia rather than mole percent.
