Perfit ZR™ TSML is an advanced 9-layer (5+4) multilayer zirconia disc designed to deliver superior translucency and natural gradient esthetics while maintaining high flexural strength. It combines incisal translucency with cervical strength, making it ideal for both anterior and posterior monolithic restorations.
🎨 9-Layer Seamless Multilayer Structure
5 main layers with 4 smooth transition zones (5+4 structure)
Natural enamel-to-dentin gradient without visible boundary lines
High translucency in the incisal zone (approx. 46–50%)
High strength in the dentin zone (up to 1,100 MPa)
Layer distribution based on 14 mm disc height for predictable esthetics
🔥 Recommended Sintering Schedule (TSML: 1,530°C, dwell for 2 hours)
For optimal translucency, flexural strength, and dimensional stability, follow the recommended sintering cycle below:
