Model: UT-ML
Type: 4-Layer Ultra Translucent Multilayer Zirconia Block
Manufacturer: HONCHON SMILE
System Compatibility: Open system / Zirkonzahn / Amann Girrbach
Indication: For anterior & short-span posterior restorations
UT Multilayer zirconia block features four-layer gradation — enamel, gradient, and dentin — designed to recreate the natural color transition of real teeth. With high translucency (49%) and a flexural strength of 650 MPa, it provides both esthetics and functional durability, closely mimicking lithium disilicate restorations.
Anterior restorations
Posterior restorations (up to 3–4 unit bridges)
