When independent Dental Product Shoppers evaluators tried out SonicFill 2 from Kerr Restoratives, they praised it as a “posterior workhorse” and a “game-changer” for direct restorations. With the introduction of SonicFill 3 SingleFill Composite System less than 3.5 years later, Kerr is out to prove that with some improvements to the formula, the so-called workhorse is off to the races, improving both efficiency and clinical results.
When SonicFill 2 was introduced, it incorporated a new filler system containing nano-scale zirconium oxide and silica oxide particles. The change delivers excellent gloss, color-matching, wear resistance, and strength to make bulk filling even easier and more reliable. With SonicFill 3, Kerr made some adjustments that further enhance the composite’s most important qualities in the posterior—handling and adaptability.
Like its predecessor, SonicFill 3 offers single-step bulk fill up to 5 mm that acts as a flowable composite during placement. But now, improved adaptation makes SonicFill 3 even easier to handle, sculpt and polish, while also being simpler to extrude during placement, as compared to its predecessors. Excellent adaptation, low shrinkage, and depth of cure make SonicFill 3 ideal for Class I, II, and V restorations, as well as core buildup. SonicFill 3 is not only a third-generation product, but offers “triple” the advantages: faster patient visits, more predictable results, and long-lasting restorations.
The Sonic Advantage
What exactly makes a composite “sonic” in the first place? This is a unique quality that sets the SonicFill system apart from others in its class. As sonic energy flows through the handpiece, viscosity drops and increases the composite’s flowability, enabling quick placement and precise adaptation to cavity walls. SonicFill becomes viscous again when sonic energy stops, creating an ideal condition for carving and contouring. After the sonic energy is removed, the material becomes non-sticky and easy to sculpt.
SonicFill 3 is designed to replace conventional time-consuming, multi-stage layering techniques with a system that eliminates the need for placing a liner or final capping layer. Even if you swear by the incremental layering technique, the 5 mm depth of cure will give you confidence during those times when you overfill past your usual 2 mm or 3 mm. Refractive index matching and an enhanced curing mechanism allow polymerization depths up to 5 mm in a single step, while still retaining opacity for esthetically pleasing finishes.
If you’re looking to perform restorative work with greater ease and accuracy, and with more predictable and reliable results than before, consider trying SonicFill 3. You can learn more about it by checking out our September issue, in which SonicFill 2 received a Readers Choice Award.
