Vsmile V SOH Tosoh Zirconia: The High-Purity Solution for Shade-Masking Challenges

The Vsmile V SOH Tosoh Zirconia is a premium dental ceramic engineered for the highest demands of versatility, strength, and shade control. Its foundation is built on 100% high-purity TOSOH Yttria-stabilized powder, guaranteeing world-class material consistency, exceptionally uniform particle size, and superior fracture toughness.
With a robust strength range of 800 MPato 1050 MPaand a versatile translucency of 43% to 57%, V SOH is the single solution your laboratory needs to confidently mill everything from delicate veneers to demanding 14-unit full-arch bridges.
I. Addressing Laboratory and Clinical Reliability Concerns
V SOH is designed to mitigate risks in the digital workflow, focusing on material pedigree, large-span safety, and predictable shade matching.
| Buyer Concern / Reliability Factor | Vsmile V SOH Tosoh Zirconia Solution | Tangible Benefit for Your Lab |
|---|---|---|
| Material Consistency & Quality Assurance | 100% TOSOH Powder: Utilizes the industry's benchmark raw material for purity and homogeneity. | Zero Surprises: Ensures predictable sintering behavior, minimal dimensional change, and uniform strength distribution in every restoration. |
| Need for Extensive Bridge Spans | High Functional Strength (800 to 1050 MPa): Certified for full contour bridges up to 14 units. | Clinical Versatility: Eliminates the need for multiple high-strength materials, consolidating your inventory while handling the longest, most demanding frameworks. |
| Comprehensive Shade Matching | Expansive Shade Palette: Includes VITA 16 Classic Shades (A1-D4) plus modern bleach shades (0M1, 0M2, 0M3, 0M3+). | Precise Matching: Covers the entire spectrum of VITA Classic and extends into VITA 3D Master-like zones, satisfying all patient shade requirements with fewer materials. |
| Susceptibility to Chipping/Fracture | High Fracture Toughness & Uniform Particle Size: Engineered for resilience under masticatory forces. | Long-Term Patient Satisfaction: Minimizes the risk of material failure in the mouth, leading to fewer remakes and chairside adjustments. |
