ST White vs HT White Zirconia Blocks

FAQ 

Q1: Is the ST White zirconia block pre-shaded?

No. It is unshaded and designed for flexible internal or external staining.

Q2: Can it be used for anterior restorations?

Yes. Its 43% translucency allows for natural anterior esthetics.

Q3: Is it compatible with CAD/CAM milling machines?

Yes. It works with most open CAD/CAM systems widely used in dental laboratories.

Q4: How does it compare with multilayer zirconia blocks?

ST White offers higher strength and customizable shade control, making it suitable for cases where staining flexibility is required.

To support digital workflows, the ST White Zirconia Block can be paired with our dry CAD/CAM milling machines, compatible with a wide range of dental zirconia blanks.

Labs can also explore our other options in the zirconia blocks series, including multilayer, pre-shaded, and high-translucency zirconia materials.
