Neo Spectra ST LV (Low Viscosity) — Universal Composite with Enhanced Plasticity

Neo Spectra ST LV is a radiopaque nanoceramic composite from the global leader Dentsply Sirona. The LV (Low Viscosity) version is specifically designed for dental professionals who prefer a soft, creamy consistency that ensures fast and effortless placement into the cavity.

SphereTEC® Filler Technology

At the heart of the material lies the patented SphereTEC® technology—the use of spherical barium glass granules. This microstructure fundamentally changes the physics of working with composite:

• Controlled Viscosity: Spherical particles allow the material to remain slump-resistant while being exceptionally pliable under instrument pressure.

• Non-Sticky Handling: Unlike traditional composites, Neo Spectra ST LV does not pull or stick to the spatula or plugger, significantly speeding up the sculpting process.

• Rapid Finishing: Due to the filler morphology, the material demonstrates exceptional polishability, allowing you to achieve a high-gloss luster with minimal effort.

Key Advantages of Neo Spectra ST LV

1. Easy Adaptation: The low viscosity (LV) allows the material to perfectly fill the micro-relief of the prepared cavity without creating voids, which is critical for the marginal integrity of the restoration.

2. Optical Integration (Cloud Shades): The "Cloud Shade" system is based on the fact that just 5 primary colors (A1, A2, A3, A3.5, A4) completely cover the entire VITA® scale range. A pronounced chameleon effect ensures that the interface between the tooth and the filling becomes virtually invisible.

3. High Strength: Despite its soft consistency, the material achieves remarkable mechanical strength and wear resistance after polymerization, making it suitable for both anterior and posterior restorations.

4. Stain Resistance: The smooth surface and specialized filler composition prevent the adsorption of food dyes, preserving the aesthetic result for the long term.

Indications for Use

The material is universal and recommended for:

• Direct restorations of all cavity classes (Classes I, II, III, IV, and V).

• Fabrication of indirect inlays and onlays.

• Splinting of mobile teeth.

Key Difference: The choice between HV (High Viscosity) and LV (Low Viscosity) versions depends entirely on your clinical preference. The LV version is ideal for practitioners who like to "spread" the material into the cavity, while HV is better suited for those who prefer a "packable" feel.
