Neo Spectra ST HV (High Viscosity) — Innovative Composite by Dentsply Sirona

Neo Spectra ST HV is a radiopaque, universal nanoceramic composite powered by the patented SphereTEC® filler technology. The HV (High Viscosity) version features a firmer consistency, providing maximum slump resistance and exceptional handling characteristics.

Key Technology: SphereTEC®

The primary advantage of this material lies in its spherical granular fillers. Unlike traditional irregular particles, SphereTEC® spheres act like "micro-bearings." This provides clinicians with unique clinical benefits:

• Superior Adaptation: The material easily adapts to cavity walls and does not stick to hand instruments.

• Precision Sculpting: The composite is highly stable, maintaining the shape of fissures and cusps perfectly until light-curing.

• Fast Polishing: The spherical nature of the fillers allows for the achievement of a high-gloss finish in seconds.

Advantages of Neo Spectra ST HV

1. Simplified Shade System (Cloud Shades): Thanks to the pronounced "chameleon effect," just 5 primary shades (A1–A4) cover the entire VITA® range. This allows for a more efficient and reduced inventory in the dental clinic.

2. Durability and Aesthetics: High resistance to staining (from coffee, tea, or wine) and low wear rates ensure long-lasting, stable clinical results.

3. Universal Application: Indicated for all restoration classes (I–V) in both the anterior and posterior regions.

4. Handling Comfort: The HV version is denser in consistency, making it ideal for dentists who prefer a more "packable" feel and total control over the composite increment.

Technical Specifications

• Filler Type: Nanoceramic.

• Delivery System: 3g Syringe.

Pro Tip: For maximum aesthetic results in large anterior defects, it is recommended to use Neo Spectra ST HV in combination with the opaque shades (Dentin) from the Neo Spectra ST Effects line.
