A Bioactive Cement that Seals Out Microleakage
The latest addition to Parkell’s growing Predicta family is a bioactive cement designed to protect crown margins and eliminate microleakage
Dental cements are the glue that holds restorations together, and when a cement fails, so does the entire restoration. So when clinicians feel confident in the cement they use, they stick with it (pun fully intended). And that’s the case for Craig Aebli, DDS, MS, FAGD, in Sanford, FL. “I’ve had the opportunity to begin using Parkell’s Bioactive Cement, mostly on zirconia and a few lithium disilicate crowns, and the results so far have been very good,” Dr. Aebli shared.
Predicta Bioactive Cement is a universal, self-adhesive, self-etching, and dual-cure cement whose chemical properties provide the traditional performance benefits found in most other resin cements. What separates Predicta Bioactive Cement from other cements, however, is its bioactivity, a component that enables a sturdy layer of hydroxyapatite to be formed across microgaps.
Closing the Gaps
Here’s how it works: The unique bioactivity formulated in Predicta Bioactive Cement allows for a continuous release and recharge of beneficial ions, including calcium, phosphate, and fluoride. This forms a dense layer of hydroxyapatite at the margins, sealing microgaps and preventing microleakage, a situation that can lead to recurrent decay. In addition, the hydroxyapatite also protects crown margins from the harsh elements normally present in the oral cavity, guards against secondary caries, and reduces sensitivity.
Indicated for luting crowns, bridges, inlays, onlays, and prefabricated metal, non-metal, and fiber posts, Predicta Bioactive Cement offers outstanding bond strength without the need for additional primers, and contains MDP for strong bonds to zirconia.
“Recently, I’ve had crowns come off on rare occasions using other products, but I have not had any instances of that with the Predicta Bioactive Cement,” Dr. Aebli said. “The bond strength appears to be quite strong. And this is the first bioactive cement I’ve been able to use in my practice.”
Radiopaque, Dual-Cure
Highly radiopaque and available in translucent and A2 shades for enhanced esthetics, Predicta Bioactive Cement is dual-curing, a feature especially noticed by Dr. Aebli.
“There are some zirconia crowns that tend to be less translucent and more opaque, and you may not get complete light penetration with your curing light,” Dr. Aebli explained. “I never want to rely 100% on light-curing cement just in the chance that the light may not penetrate the crown completely, so for that reason, it’s an added benefit that this is a dual-cure cement, because I always do both,” he added.
“This cement gives me the added confidence that it’s actually helping to prevent microleakage, which makes me feel better, and of course, leads to better results for my patients.”

Handling & Cleanup
Another feature particularly appreciated by Dr. Aebli is the material’s viscosity and low film thickness, which result in fast and easy cleanup, as well as complete seating of the crown.
“I’ve had no difficulty getting the excess material off in between the teeth,” Dr. Aebli said. “In the past, I have used some cements that had a self-cure component and set so rapidly I found the cement hardened in between the tissue and the teeth, but I haven’t had that issue at all with Predicta Bioactive Cement.”
Bioactivity for the Win
Overall, the unique bioactive formulation of Predicta Bioactive Cement—which allows it to fill and seal microgaps and prevent microleakage—is the leading characteristic that’s earned the product a spot in Dr. Aebli’s armamentarium.
“Ideally, you want your margins to be closed with the fit of a crown, and this cement gives me the added confidence that it’s actually helping to prevent microleakage, which makes me feel better, and of course, leads to better results for my patients,” he added.
