VOCO Unveils GrandioSO 4U Universal Nanohybrid Composite

---

VOCO’s new GrandioSO 4U—a decade in the making—is a 91%-filled universal nanohybrid composite. It has tooth-like physical properties, including modulus of elasticity, flexural strength, thermal expansion behavior and more.

After 10 years of research and development, VOCO has set the bar even higher with this new universal composite. With an extremely low shrinkage of just 1.44%, and exceptional wear resistance, it delivers unmatched longevity.

Utilizing Visual-Transformation-Technology (VTT)—which enables a pre-cure translucency for a 4mm depth-of-cure and post-cure opacity for excellent aesthetics— GrandioSO 4U is formulated to deliver a perfect balance of bulk fill strength and speed and esthetics suitable for the anterior. Its Cluster-Shade system covers all 16 classic VITA shades using just 5 cluster shades, significantly streamlining inventory and shade selection. According to VOCO, 30% to 50% less resin compared to classic composites gives GrandioSO 4U a superior, non-stick consistency and makes the material extremely color stable; 900 %Al radiopacity sets a new standard for x-ray identification.

Unlike traditional layering composites or less aesthetic bulk fills, GrandioSO 4U delivers both simplified workflows and superior outcomes in a single material.
