VisCalor Bulk Capsules

VisCalor bulk from Voco is a Thermoviscous Bulk Fill Composite combining the flowability of a flowable composite during application with the sculptability of a packable composite.

Packable bulk-fill composites are suitable for the reliable filling of large posterior cavities as part of secondary treatments. These materials cannot easily be used to fill very deep and narrow cavities that have undergone defect-oriented and minimally invasive preparation: perfect adaptation to the cavity floors and walls is often difficult to achieve. The use of flowable composites as base materials is a good alternative for this type of deep, narrow cavity, but they still need to be coated with a covering layer of packable composite. This two-phase process makes placing a restoration a time-consuming task.

VisCalor bulk follows a completely new approach: the material combines the flowability of a flowable composite during application with the sculptability of a packable composite. VisCalor bulk is therefore a material that can be used for both large and narrow cavities, without having to compromise with regards to adaptation or strength.

How does it work?

As VisCalor bulk is heated using a preheating device for composites, it becomes less viscous, allowing for application similar to that for a flowable material. The material flows optimally on cavity walls and undercut regions.

The material quickly cools back down to body temperature and can immediately be sculpted just like a packable composite.

As a result, VisCalor bulk offers the benefits of both a flowable composite and a packable composite during the placement of a restoration. This allows for efficient single-phase restorations without multiple working steps for base filling, increments or covering layers.

VisCalor bulk is the world’s first material to use thermo-viscous-technology. The special surface treatment on the fillers and a coordinated resin matrix help to significantly extend the normal viscosity reduction effect when the temperature is increased. This results in a material that acquires the consistency of a flowable material when heated up in a standard 68 °C composite warmer, or to full benefit in the new VisCalor Dispenser, but that is sculptable like a packable composite at body temperature.

Indications

• Class I and II posterior restorations
• Base in class I and II cavities
• Class V restorations
• Locking, splinting of loose teeth
• Repairing veneers, enamel defects and temporary C&B-materials
• Extended fissure sealing
• Restoration of deciduous teeth
• Core build-up

Advantages

• Unique and innovative – Heating of the material makes it flowable for the application and then sculptable immediately afterwards (thermo-viscous-technology)
• High-quality application – Optimal flowing to margins and undercut regions
• Time-saving – No covering layers required
• Simple handling – 4 mm bulk fill and bubble-free application with slender cannula
