Ceramir Crown & Bridge gets you close to natural tooth structure

One difference, according to Emil Abrahamsson, president of Doxa Dental, is that Ceramir has the unique ability to make tight and impermeable contact with tooth tissue that is stable over the long term. In fact, no cement is closer to natural tooth structure than Ceramir, according to the company.

Abrahamsson spoke with Dental Tribune at the recent ADA meeting in Las Vegas.

This is because Ceramir fosters a build-up of nano-crystals that integrate with dentin and enamel, forming a biomimetic material that the company calls “nanostructurally integrating bioceramics” (NIB). The scanning electron microscope images, showing how at 20 nm (the molecular level) Ceramir integrates with dentin in vitro, are quite compelling and can be seen at the booth.

Another dramatic difference in comparison to other cements is that Ceramir creates an alkaline environment (high pH) that resists acid and bacterial decay. Thus, the product remains chemically stable in the oral environment over time. Because it was designed to be stable in an oral environment, Ceramir does not require optimal conditions for a good seal.

The questions on everyone’s mind when discussing dental cement usually revolve around working time, setting time, film thickness and mechanical strength. Ceramir’s working time is two minutes while its setting time is approximately five minutes.

In addition, Ceramir meets the film thickness for well-fitting restorations by coming in at around 15 µm.

Finally, Ceramir’s mechanical strength was measured in terms of compression strength and, after 24 hours, was measured at 170 MPa.

Ceramir Crown & Bridge cement is backed by 25 years of research and development by Swedish Professor Leif Hermansson and his wife, Irmeli, founders of Doxa Dental.
