High Translucency 3D Multilayer Zirconia Block Dental Zirconia
Blank 98*16mm
Product Description
Our Zirconia Block be made of the biological nano zirconia powder
with isostatic pressing method and keep processing in machine
center.We can do the zirconia block according to the clients the
requirement.
Advantages of zirconia
1). Natural gradient COLORS.
2). Perfect translucent incisal
3). Simple operation, no need inner dyeing, simple external dyeing
is OK
Simply to be Natural
