High Translucency 3D Multilayer Zirconia Block Dental Zirconia Blank 98*14mm
Product Description
Zirae multilayer zirconia saves the procedure of internal shading, and perfectly solves the uneven shading and unnatural color transition problem. It can easily restore teh vivid aesthetic effect from the neck of the teeth to the incisal edge of the teeth, just like human natural teeth.
