Retaining the same patented sonic-activation technology that made the original version so successful, special rheological modifiers in the SonicFill 2 filler system have a dramatic reaction to the sonic energy applied through the handpiece during placement. This reduces the viscosity of the material up to 84% creating adaptation similar to a flowable, to ensure intimate adaptation between the composite and bonded surface.
The new filler system also enables excellent gloss, color-matching, wear resistance and strength to make bulk filling even easier and more reliable.
