Key Features

SonicFill is the first of its kind – a time-saving, single step, bulk filling system for posterior restorations.


RRP £795 for the introductory kit. In addition, the handpiece is available free of charge with the purchase of 10 refill packs (each refill pack comprises 20 x 0.3g compules and costs approximately £50).

The SonicFill system comprises a KaVo handpiece that enables sonic activation of a specially designed and conveniently delivered composite from Kerr. SonicFill’s proprietary sonic activation significantly reduces the composite’s viscosity to fill the cavity quickly.

Essentially, it is:

  • Fast – single-step bulk filling of up to 5mm saves time. Placement to polish takes less than three minutes
  • Reliable – it provides predictable, long-term restorations as a result of its improved adaptation and reduced shrinkage
  • Easy – with optimal non-sticky, non-slumping handling of the composite and convenient delivery through a small cannula.

SonicFill’s composite incorporates a highly-filled proprietary resin with special modifiers that react to sonic energy. As this sonic energy is applied through the handpiece, the modifier causes the viscosity to drop (by up to 87%), increasing the flowability of the composite. This enables quick placement and precise adaptation to the cavity walls. When the sonic energy is stopped, the composite returns to a more viscous, non-slumping state that is ideal for carving and contouring. The composite in the phase of sculpting is highly responsive to the shear stress and allows tight adaptation in the cavity.

Increased levels of photo-initiators in the composite material allow a full 5mm depth of cure in 20 seconds with as little as a 500mW/cm light source.

In addition, SonicFill’s higher translucency does not compromise aesthetics.
