THE EVOLUTION OF TODAY'S ZIRCONIA
​
​
​
GENERATION 1
The traditional full strength zirconia options which were initially established in the dental field, like BioZË£², can
be grouped together as 3Y TZP ceramics. These materials feature a 3% yttria oxide formulation, providing maximum
strength (>1,250 MPa’s of flexural strength/8.3 K1C fracture toughness) with approximately 40% translucency.
​
GENERATION 2
cubeX² Ultra-Translucent Zirconia was introduced to the dental market in 2016 as a translucent cubic 5Y TZP ceramic.
cubeX2 features a 5% yttria oxide formulation, providing a maximum 49% translucency with median strength
(>750 MPa’s of flexural strength/4.8 K1C fracture toughness).
​
GENERATION 3
The new cubeONE is a third generation zirconia that blends the best features of the first two generations…ideal
translucent esthetics with maximum strength. cubeONE is a 4Y TZP formulation, providing a 45% translucency,
maximum strength (>1,000 MPa’s of flexural strength), and an increased 9.0 K1C fracture toughness. Additionally,
cubeONE features the original Phase Toughening Effect for high impact resistance that is characteristic
of the first generation full strength zirconia materials.
