Evaluators’ Comments

“Great product! I plan to start using more.”
“The increase in inherent strength of the material is very appealing. This material can be prepped down to 0.6 mm which is appealing. Shade comparison is very close to the VITA guide and looks quite nice next to opaque teeth and older PFM crowns.”
“Very strong and durable material. In posterior locations where esthetics are less important, this block worked beautifully.”
“Takes longer to fire. Also, you have to remember to designate the shade in the CEREC software.”
“I love the 0.6 mm of reduction, the margins are absolutely amazing, and the mill time is great too.”

Description

CEREC MTL Zirconia Blocks are partially sintered zirconia blocks that are then milled and fully sintered to give flexural strengths over 850 MPa. They are available in 11 shades in both mono and medi blocks.

Unique Attributes

Ability to prep to 0.6 mm as opposed to the traditional 1.0-1.5 mm, up to 40% lower reduction of the tooth.
Specific firing for different shades.
Faster milling time if using the Super-Fast Milling setting – around 5 minutes.
Multi-transitional layering of the material assists in a greater esthetic outcome.

Clinical Tips

Make sure to have enough occlusal reduction if you want to carve in more occlusal table anatomy. Post-milling finishing is required.
Posterior crowns are the proper location unless function is more of a concern than esthetics.
Polishing technique: use a light touch. Be certain to polish over areas that are adjusted to reduce the abrasive nature of the material.
