Confident restorations begin with a durable, reliable adhesive bond. With Prime&Bond active^®, Dentsply Sirona is launching a universal adhesive that meets this requirement. It is formulated to actively guard against the leading causes of adhesive failure, even when dentin is very wet or dry. 

Charlotte. Dentsply Sirona has recently launched the Prime&Bond active^® Universal Adhesive to the market. Designed for all etching methods and indications, Prime&Bond active^® features patented Active-Guard™ technology—a significant advancement in adhesive chemistry that actively controls moisture on the prepared surface. Even if dentin is very wet or dry, Prime&Bond active^® is simple to use and provides consistent results for a strong, reliable bond.

Most dental adhesives are rather hydrophobic: they separate from water. With too much water on the prepared surface, these adhesives fail to cover the prepared surface uniformly. During air-drying, adhesive gaps can form due to embedded pockets of water evaporating, increasing the risks of post-operative sensitivity and bond failure. With Prime&Bond active®, dental professionals can focus on the treatment with confidence, knowing that their performance and efficiency are optimized. Dentsply Sirona is committed to providing solutions that enable dental professionals to consistently deliver the best clinical outcomes possible for their patients.

Active-Guard™ technology is designed to protect against these risks

Patented Active-Guard™ technology balances hydrophobic and hydrophilic properties and helps achieve optimal surface tension. Prime&Bond active^® Universal Adhesive with Active-Guard™ technology thus overcomes the surface tension of water, allowing the dental adhesive to spread evenly across the dentin and into the dentinal tubules to form a uniform, homogeneous layer. When the adhesive is air-dried, solvent and excess water evaporate leaving a thin, consistent coating of adhesive across the entire surface. The result is a strong, reliable bond, with virtually no post-operative sensitivity(1). In a user survey with more than 2,000 restorations, the incidence of post-operative sensitivity was less than 0.2% using Prime&Bond active^® Universal Adhesive(2) .

The dental adhesive proves to be a critical factor in Class II restorations. “Especially when used with a bulk-fill flowable like SDR^® flow+, Prime&Bond active^® adhesive helps achieve gap-free restorations with efficiency and predictability,” emphasizes Dr. Nichole Lubberts, dentist from Grand Rapids, MI, USA.

Prime&Bond active® offers dentists numerous benefits:

- Active spreading across the prepared surface minimizes the risk of dry spots that can lead to post-operative sensitivity and micro-leakage.

-  Low film thickness(3), minimizing the risks of changing the preparation geometry and compromising crown fit, or leaving adhesive pools that may show up on radiographs and be misdiagnosed as voids, gaps or secondary decay.

- No need to apply an activator when used with Calibra^® Ceram cement.

- Convenience and control, with one-handed opening of the Flip Top Cap bottle, precise dispensing and up to 30 minutes of working time in a closed CliXdish™.

- Innovative formulation without HEMA, TGDMA or Bisphenol

"Prime&Bond active^® with patented Active-Guard™ technology is an adhesive that is easy for dentists to use and reliably helps ensure a strong bond," said Julie Mroziak, Vice President Restorative Solutions at Dentsply Sirona. "It is important to us as a company to provide dentists with solutions that enable them to achieve clinically superior results, so they can advance care for their patients with confidence.”
