Perfit ZR STML is a Multilayered zirconia that has Esthetic multilayers with a moderate strength so a Single Crown(Posterior, Anterior), a Screw-Retained Crown, Posterior Bridges(up to 3 units) can be created. By the multilayers of natural gradation and high strength, it is possible to create restorations with high aesthetics.

Sintering
Volume change at 1,000℃, changing color at 1400℃, and coloring liquid diffusion at 1450-1550℃ are generated for zirconia.
Usually, sintering temperature at long time is stable for volume change, flexural strength and translucency.
