Ultra Translucent Multilayer Zirconia

UT Multilayer-Ultra Translucent Multilayer
Our ultra translucent Multilayer zirconia has the 4 layers. It includes the Enamel layer, Gradational Layer and dentin layer. This multilayer has top translucent, it can make the similar translucency like lithiu
Description

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


Product Description

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.


 Recommended Indications

  • Anterior restorations

  • Posterior restorations (up to 3–4 unit bridges)

  • Telescopic crowns

  • Inlays, onlays, partial crowns

  • Veneers, full-contour crowns
