EVALUATORS’ CHOICE AWARDS: GC AMERICA - Leading the Recharge for Healthier Oral Care

Published Date 07/11/2019
Nearly 100 years ago, 3 recent graduates from what is now the University of Tokyo started a small research company called General Chemical (GC). Full of ambition, they wanted to help end to the country’s reliance on imported dental materials. They struggled early on to launch their first product, but quickly learned from their mistakes. To be successful, they decided that they needed to think from the customer’s perspective.

When it comes to dentistry, the customer is actually 2 people: the clinician providing treatment and the patient receiving it. GC America knows this well and has made a commitment to creating high-quality products that simplify dental professionals’ time in the operatory while elevating the oral health of the patients in their care.

The products and their associated families showcased here exemplify GC’s commitment to manufacturing solutions from a customer’s standpoint. But they also share a common thread in their design when it comes to repairing, recharging, and remineralizing teeth—allowing dentists to provide minimally invasive treatment so that patients can preserve more of their natural smile.

Power to the Tooth
Whether used as filling materials or luting cements, GC America’s robust lines of glass ionomers and glass hybrids cover a wide range of clinical scenarios and restoration types. GC Fuji II LC has been a mainstay for years in Dr. William Lieberman’s Red Bank, NJ, pediatric dental practice. He prefers the quick light-cure over a self-curing material, especially when it comes to treating difficult-to-manage younger patients.

“In a pediatric practice, glass ionomers allow us to help remineralize surrounding tooth structure,” he explained. “They also increase our speed of treatment, and with children, time is of the essence.”

GC Fuji II LC is a triple-cured, resin-reinforced glass ionomer restorative material that also can be used as a base under composite resin and amalgam, or as a temporary restorative. The light-curing material offers high fluoride release.

“In addition to adhering to tooth structure, it’s important for a glass ionomer to be bioactive and release fluoride back into the tooth, and then to recharge itself and continue releasing fluoride,” said Dr. Lieberman. “GC Fuji II LC lets me do this in a consistent manner that is appropriate for my pediatric population.”

It’s All in the Delivery
Building on the clinical success of Fuji II LC, GC Fuji Automix LC offers automix delivery through an ergonomic dispenser that allows precise placement into the preparation. Dr. Lieberman said this system allows access to critical locations in smaller mouths.

“I especially like using it in permanent posterior Class IIs, where I can get the tip down into the proximal box and use the squeegee in an open sandwich technique,” said Dr. Lieberman, adding that he is continually “wowed” by the system and looks forward to using it in more situations.

“There is a true chemical bond between calcium in the tooth to the matrix in GC Fuji Automix LC.”
GC Fuji Automix LC’s range of indications includes primary teeth restorations, permanent Class III and V restorations, core buildups, and use as a base material for Class I and II cavities in the sandwich technique. The bioactive material forms a chemical bond to the tooth while offering high, rechargeable fluoride release.

“There is a true chemical bond between calcium in the tooth to the matrix in GC Fuji Automix LC,” said Dr. Brian Nový, Director of Clinical Innovation at DentaQuest. “As a result, the restoration margin is one of the strongest parts of the restoration, whereas in other restorative materials, it’s your weakest part of the restoration.”

Meet the MI Family
GC’s bioactive philosophy carries over to hygiene, as well. Part of the MI family of solutions, MI Varnish uses a proprietary RECALDENT-containing formulation to encourage a high release of tooth-building ions. RECALDENT is casein phosphopeptide-- amorphous calcium phosphate (CPP-ACP), a special milk-derived protein that has a unique ability to release bioavailable calcium, phosphate, and fluoride ions to tooth surfaces. The addition of calcium and phosphate ions offers patients added protection through enhanced enamel acid resistance and higher salivary fluoride levels.

Hygienist Charity Torpey shared that the primary reason why her practice uses MI Varnish is because of its high calcium and fluoride release. “I also like its ease of use—it goes on smooth and doesn’t seem to separate as much as others do in the packaging,” she said. “I think the container is more user-friendly than the bubble packs other varnishes use.”

RECALDENT is also the force behind MI Paste ONE, a toothpaste therapy that treats hypersensitivity, promotes remineralization, and prevents tooth erosion, caries, and white spot lesions. Instead of brushing first and then applying topical tooth crèmes MI Paste or MI Paste Plus, patients can simply brush with MI Paste ONE.

MI Paste ONE offers an added bioactive benefit to patients after restorative procedures. Glass ionomers such as GC Fuji Automix LC have the ability to absorb fluoride (recharge) from MI Paste ONE* and slowly release it into the tooth. In addition, calcium and phosphate ions work in tandem with the fluoride in toothpaste to treat sensitivity, help remineralize tooth enamel, and prevent caries and white spot lesions.

“With this rechargeable phenomenon, which is just awesome, you have a restorative-toothpaste combination that actually fixes the hole in the tooth, repairs the tooth from inside, and continues to recharge and release fluoride,” said Dr. Nový.

*Data on file
Perhaps one of GC America’s most recognized and celebrated resinreinforced glass ionomer cements is the second generation in its GC FujiCEM line. GC FujiCEM 2 pairs with a wide array of indirect restorations, including all types of metal-, resin-, alumina-, and zirconia-based inlays, onlays, crowns, and bridges.

Powered by F2 Fuse Flex Technology—a combination of high-elastic crosslinking monomers with a modified filler-surface treatment—GC FujiCEM 2 offers increased strength, high-fluoride release, and low-film thickness. These features ultimately give clinicians extra time for other clinical tasks.

A Fluoride-Releasing Favorite
During its DPS product evaluation, a team of clinicians tested GC FujiCEM 2 in their practices and awarded it with a nearperfect score of 4.9 out of 5—cementing its place among a very small group of other high-scoring DPS Best Products. Evaluators particularly lauded its handling, consistency, and easy cleanup, with one clinician saying, “This is a very simple, foolproof system with easy cleanup and a great bond.”

DPS evaluator Dr. Nageen Rak said she trusts GC America products and has been using GC FujiCEM 2 for the past few years to cement porcelain-fused-to-metal, cast, and porcelain crowns in her practice. “I particularly enjoy the ease with cleanup, as the cement is easily removed around the margins post insertion,” she shared.

Another big perk for Dr. Rak has been GC FujiCEM 2’s high fluoride release. “I let every patient know that there will be a fluoride release in the cement that will help strengthen the tooth that is crowned,” she said. “Patients love hearing that the cement is not only used for retaining the crown, but also for protecting the tooth.”
