This year marks a significant moment for SDR Flow – the revolutionary bulk-fill composite from Dentsply Sirona – as it celebrates 15 years of enabling faster, reliable direct restorations in dental practices worldwide.

Launched in 2009, SDR (Smart Dentin Replacement) bulk‐fill technology has grown into a gold standard for posterior restorations and beyond. Over the years, it has been applied in over 135 million restorations and is backed by long-term clinical studies spanning 5- and 6-year follow-ups.

Celebrating 15 years of innovation

From its early days, SDR differentiated itself by being a flowable bulk-fill composite that allowed dentists to work in thicker increments (up to 4 mm) rather than the traditional layering approach. This meant fewer steps, less chair time and a material engineered for predictable adaptation and low polymerisation stress.

Over the last decade and a half, SDR Flow strengthened its position through continued study and refinement. Its journey reflects how dental restorative materials have evolved – from incremental layering techniques to sophisticated bulk-fill systems enabling efficiency without compromising durability or aesthetics.

The evolution of the technology - from the original SDR to SDR flow+ with improved wear resistance, expanded shades and radiopacity - demonstrates the commitment to continuous innovation.
