Perfit ZR™ TSML
- Multilayered Zirconia
- Seamless 5+4 multilayers with natural gradient color and high strength
- Two different types of raw material are used for Perfit ZR TSML
- high translucency on the incisal and strength on the cervical
- Translucency: 46% / Flexural Strength: 1,100MPa

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.
