SphereTEC® Filler Technology

TPH Spectra® ST composites excel where it counts thanks to SphereTEC® Filler Technology.

Key performance advantages of TPH Spectra® ST composites were made possible with SphereTEC® Filler Technology. The SphereTEC® fillers’ morphology, particle size distribution, and surface microstructure deliver the benefits that matter most to dentists.


Easy handling for efficient placement: The shape and size distribution of SphereTEC® fillers create a ball-bearing-like effect that enables excellent adaptation and sculptability. They bind more free resin than usual fillers to avoid stickiness.

Natural chameleon blending capability: SphereTEC® fillers are uniquely constructed to balance opacity, translucency, light absorption and scattering for a superior chameleon effect. Their microstructure enables a fast polish to a high gloss.

Durable results for happier patients and a profitable practice: High filler packing density, plus micro-mechanical locking of our resin and fillers, deliver strength and durability. Patients will also love the exceptional stain resistance, thanks to our resin-infiltrated, prepolymerized filler design.
