UT-ML

Ultra-Translucency Zirconia

UT-ML. Ultra-Translucency. Ultimate Aesthetics

See Through Beauty. Built for the Spotlight

Introduction

Engineered for high-end anterior restorations, UT-ML offers a remarkable blend of translucency (49–53%) and natural gradient shading across 9 layers—no staining required. With 600–800 MPa flexural strength, it’s ideal for crowns, veneers, and inlays where beauty and precision matter most. Available in VITA 16 and Ivoclar B4 shades, UT-ML delivers consistent, lifelike results that turn smiles into statements.
