Product Descriptions
XTCERA blanks are made from biocompatible zirconiumdioxyde. The yttrium oxide stabilizing protects the material against cracks and increases the tensile and compressive strength. The special grain size allocation inside the material and the added aluminium oxide also result in extra strength during milling and subsequently in clinical use.
The outstanding mechanical characteristics, excellent chemical durability and the unbeaten biocompatibility
combined with the translucent color predestine XTCERA as the ideal material provider for dental milling systems.
