The KDZ Ultra is a very popular restoration here at Keating Dental Arts. What are the advantages of the Ultra. We really have the best of both worlds. We have the strength of zirconia and then we the ability to overlay with beautiful powder liquid ceramic so we get the depth that we frequently saw with the PFM. A lot of our monolithic zirconia most of our color comes from superficial staining. Where the Ultra we overlay on top of it. That's one of the biggest advantages. When I want to maximize strength and maximize aesthetics the KDZ Ultra is a restoration of choice.
