SDR Plus We've made the first a few shades better.

SDR Plus is the improved next generation of the leading and still unmatched flowable bulk-fill material SDR.

The unmatched SDR bulk fill technology

In 2009, SDR was the first technology that allowed 4mm bulk placement in flowable consistency. More than 50 million applications and several long-term clinical studies later, it is the bulk fill technology of choice for faster and easier creation of reliable direct restorations. SDR technology answers the two challenges of direct restorations: adaptation and efficiency.

Adaption is the key to long term success

  • Voids and gaps between restoration and cavity walls directly influence secondary caries formation1
  • Improper adaptation of composite during placement leads to the formation of voids2
  • High shrinkage stress may lead to marginal gap formation2

Low shrinkage stress

During light-cured polymerization, resin monomers are in chaotic movement as they begin to form the polymer matrix. SDR technology enables the formation of a more relaxed network, minimizing the build-up of stress. This reduces the risk of gap formation during polymerization.

SDR’s unique chemistry helps ensure the longevity and overall quality of a bulk fill restoration. SDR flowable bulk fill technology fills and easily adapts to the cavity, flowing into nooks and crannies to provide excellent cavity adaptation during placement.

Efficiency is the key to productivity

Direct restorations represent approximately a third of the annual revenue of a general practice. Increasing the efficiency of the Class II treatment directly impacts day-to-day dental office revenue.5,6 SDR bulk fill technology allows the material to be applied in 4mm increments without an additional liner. This automatically decreases procedural time and inventory.

  • Self-levels for up to 40% time savings over classic layering technique
  • Use without an additional liner
  • Self-levels and does not require additional manipulation to adapt

More Versatility

The upgraded formulation of SDR Plus material adds even more versatility, by introducing new shades and expanding the range of indications.
