New Chemistry opening doors

Authors: Gary Radz, DDS

"Currently, most of the composite resins in the dental market show volumetric shrinkage of 2% to 3.5%. N'Durance demonstrates a shrinkage rate near 1.5%. This may not seem like much of a difference, but clinically this could mean this difference between microleakage and recurrent decay or sensitivity. Also by decreasing the shrinkage, you decrease the stress of the restoration on the tooth itself.
Additionally, this new chemistry has a high monomer conversion. This material, when fully polymerized, will have 75% conversion rate is important because it allows for improvement in the material's physical properties. 
The new chemistry in N'Durance could open the door to the next generation of composite resins, allowing us to provide our patients with stronger, longer lasting esthetic composite restorations. 
[…] Septodont's new chemistry has brought a significant new technology to the field of composite resin science. This new chemistry provides for several physical property improvements that allow us to come closer yet to the ideal composite resin restorative material."
