Kerr will launch Herculite Ultra, a new version of Herculite composite with nanofiller, February 1, the company announced.
The resin matrix of the 20-year-old Herculite will remain the same, according to Kerr, but the company has added nanofiller with the goal of increasing gloss and strength.

Nanofiller is made up of nanoparticles -- particles in the range of 5 to 100 nanometers (nm). When combined with conventional hybrid fillers, these composite resins are called nanohybrids. Altogether, the Herculite Ultra will contain three fillers: prepolymerized filler (PPF), nanoparticles (50 nm), and a submicron hybrid filler (0.4 µm).
"Our goal for Herculite Ultra was to retain the resin chemistry, tooth translucency, and comprehensive shading to retain the aesthetics and clinical performance of Herculite," said Principle Scientist Al Kobashigawa. "The new submicron nanohybrid filler technology improves handling, polishability, clinical gloss, and wear resistance; and new additives improve aesthetics with fluorescence and opalescence."
