One of the great things about CAD/CAM dentistry is the evolution of the materials! It is fantastic to see companies with great reputations in materials, like Noritake, join in with their own blocks!
Noritake is releasing a zirconia block and a composite resin block to the US market! It is estimated that it will be the end of 2017 or early 2018 for their availability. The composite block is already being used in Japan.
Both blocks are POLYCHROMATIC!
Composite block = Avencia
Zirconia Block = Katana
