ACTIVA BioACTIVE Bulk Flow Marks Pulpdent’s First Major Product Release in 4 Years

Pulpdent Corporation has expanded its flagship ACTIVA line of groundbreaking dental restorative materials with the introduction of ACTIVA BioACTIVE Bulk Flow. The new product is designed to raise the standard of care for bulk-fill procedures by supporting the natural remineralization process,1 providing defense against secondary caries,2 and offering optimal esthetics through its ShadeFusion™ universal shade matching technology.

Pulpdent adds that ACTIVA BioACTIVE Bulk Flow also gives dentists a powerful new tool to perform Class II restorations, one of the most common treatments in dentistry.

As a next-generation product, the new material not only raises treatment standards, but also overcomes efficiency limitations of traditional bulk-fill materials. For example, ACTIVA BioACTIVE Bulk Flow offers unique protection against shrinkage stress and wear through its patented stress-reducing monomer, MODULUS™.

For practitioners, it provides a true self-leveling and 1-step bulk-fill solution thanks to its unlimited depth of cure and ability to be used without a capping layer, according to Pulpdent. When taken together, ACTIVA BioACTIVE Bulk Flow’s unique properties empower providers to improve patient care while boosting chair-time efficiency and practice production.

“ACTIVA BioACTIVE Bulk Flow is an exciting step forward, both for dentistry and our company,” Michael Jeffery, Pulpdent Director of Product and Strategy, says in a press release. “We believe ACTIVA BioACTIVE Bulk Flow ushers in a new, higher standard of care for dental patients worldwide. The product also provides immediate cost-saving efficiencies for today’s business of dentistry. This is particularly true of ACTIVA BioACTIVE Bulk Flow’s ability to simplify Class II procedures, one of the most common yet challenging treatments in general dental practices, pediatric dental practices, and DSOs [dental service organizations] today.”

In recent years, bulk filling has become a mainstay procedure for the treatment of dental caries and other restorative needs. However, in some cases confidence in existing bulk-fill materials is often compromised due to challenges with photopolymerization and shrinkage stress, as well as bulk-filled restorations’ susceptibility to microleakage, bacterial incursion, and restorative failure. Pulpdent states traditional limitations were squarely in mind with the development of ACTIVA BioACTIVE Bulk Flow, which is formulated to address each of these shortcomings head-on.

ACTIVA BioACTIVE Bulk Flow self-levels easily, flows naturally, and exhibits elevated chroma and translucency matching. Independent testing demonstrates ACTIVA BioACTIVE Bulk Flow provides superior protection against microleakage,3 volume wear,4 and shrinkage stress5—all at thresholds that meet or exceed existing standards for top-tier restorative materials.

The viscosity of ACTIVA BioACTIVE Bulk Flow is ideal for various clinical situations. For example, in cases requiring restoration of deep boxes and cavernous lesions, the material ensures proper treatment thanks to its flowability and dual-cure properties. With its unlimited depth of cure and no layering/capping requirement, dentists can be confident that the risk of voids is minimized, according to the manufacturer. Furthermore, ACTIVA BioACTIVE Bulk Flow provides an option for dentists who appreciate ACTIVA’s bioactive properties, but desire working without a dispenser. ACTIVA BioACTIVE Bulk Flow simplifies inventory thanks to ShadeFusion universal color matching, while the material is sufficiently radiopaque so dentists can be confident that it will be visible for any clinician evaluating their patient for years to come.

For pediatric dentistry, ACTIVA BioACTIVE Bulk Flow is available in a special formulation for primary dentition, ACTIVA KIDS BioACTIVE Bulk Flow. This version of the product has all same properties as ACTIVA BioACTIVE Bulk Flow, but offers 2 esthetic options optimized for children’s teeth, states Pulpdent. ACTIVA KIDS BioACTIVE Bulk Flow’s universal shade matches primary dentition, while an opaque white shade is available for when visible restoration margins are desired. As with all members of the ACTIVA family of restoratives, ACTIVA KIDS BioACTIVE Bulk Flow contains no BPA, no bis-GMA, and no BPA derivatives.

“ACTIVA BioACTIVE Bulk Flow is a natural expansion of our ACTIVA research that relieves critical pain points for dentists,” adds Lew Berk, Pulpdent managing director. “The product is a perfect complement to our existing ACTIVA line, while offering new users a novel material choice for their practice style. ACTIVA BioACTIVE Bulk Flow reflects our longstanding mission—first espoused in 1947 by Pulpdent founder Dr. Harold Berk—to save teeth and help patients live in comfort and smile with confidence. It also meets our vision to empower dentists with higher standards of care and new practice efficiencies. From our R&D scientists to our manufacturing specialists, I’m very proud of our team and pleased to introduce ACTIVA BioACTIVE Bulk Flow to dentists around the world.”

The new product was unveiled recently at the 2024 Greater New York Dental Meeting and is available for pre-market ordering at https://www.pulpdent.com/best-bulk-fill. It will begin rolling out to Pulpdent’s global network of distribution partners for sale and shipping on January 1, 2025. The product comes in a 5g syringe and includes 10 Automix tips. As with all Pulpdent products, ACTIVA BioACTIVE Bulk Flow is made in the USA to the highest quality assurance standards in Pulpdent’s manufacturing facilities in Watertown, Massachusetts.
