SDR Plus I Dentsply Sirona India

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.

Flowability

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.

More Versatility

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

More Shades

In addition to one universal shade, three new A-shades of SDR Plus - A1, A2, and A3 - increase versatility even further in a wide range of cases including visible Class II restorations, primary posterior dentition, Class III and Class V restorations.

More Indications

Additional oportunities to use SDR Plus material.

+ Class III and V Restorations

Due to its unique chemistry and improved wear resistance, SDR Plus material is now approved to be used in Class III and Class V restorations where a capping agent wouldn’t be used. This expands its capabilities to be used in more restoration classes than many other flowable material.

+ Primary Posterior Dentition

SDR Plus material can be used without an additional universal composite and in increments up to the occlusal surface. Fast and easy application technique make it ideal for the treatment of children.

+Pit & Fissure Sealing

The thin compule allows the material to flow easily into all fissures for highly precise application.

+Core Build-Up

The 4mm depth of cure of SDR Plus material make it a fast and easy alternative for core build-up. It handles instrumentation and shaping with ease.

Reliable adhesion and tight seal in high C-factor endo cavities

+ Reliable adhesion

Endodontic cavities are particularly challenging for bulk fill composites, as most are very deep Class I cavities. This maximizes shrinkage stress potential, indicated by a high C-factor. Studies indicate that when high C-factor cavities are filled in bulk, the choice of the composite is an important element to avoiding adhesive debonding.8 SDR Plus material with SDR technology can deal with high C-factor cavities, leading to a tight coronal seal even for post-endodontic cavities.

Years of clinical success

While making Class I and Class II restorations faster and easier, the SDR technology in SDR Plus material also shows excellent long-term reliability in several clinical studies. In fact, the long-term survival rates of bulk fill restorations with SDR technology provided to be equivalent to those of restorations done in the conventional layering technique.

_{JWV van Dijken and U. Pallesen¹¹}

“During the six year follow up, the bulk fill technique was proven to be a clinically safe technique; highly acceptable; clinically durable.”

A total of 183 Class I and Class II restorations were evaluated at recall. 92 using SDR and Ceram·X in the bulk-fill technique against 91 using just Ceram·X composite in the layering technique. The observers conclude:
