This patent-pending device is the first of its kind, using NIR (near infrared) technology to rapidly warm highly filled composite compules. With the touch of a button, VisCalor® Dispenser is able to heat composite material to 65°C (150°F) in seconds, and maintain that temperature throughout the procedure. Warming composite significantly lowers the viscosity of the material resulting in better adaptation, reduced voids and microleakage. Materials remain highly sculptable, non-sticky, and easily shaped during manipulation.
