Root Canal Treatments: New Composite

New root canal components are being developed by researchers at the Fraunhofer Institute for Silicate Research ISC in Würzburg working in collaboration with VOCO GmbH.

“The basis of this material is provided by ORMOCER®s,” explains Dr. Herbert Wolter. “We have combined these ORMOCER®s with various nano- and microparticles to achieve the highly diverse properties needed.”

Materials used in filling the root canal should not shrink as they harder, be visible in x-rays, and should form an airtight bond with the dental material. However, the material used to rebuild the tooth, should have the same properties as the tooth itself.

“Hybrid materials are well suited to these requirements. For instance, they only shrink by about 1.3 percent as they harden, while standard materials generally shrink by 2 to 4 percent. ORMOCER®s can also be adapted to adhere to the different parts of the tooth,” says Wolter.

VOCO GmbH is producing dental preparations. Product launch is coming along and could be within the next 2 years.

This could potentially help lessen the number of crowns that needed to be replaced due to breaking.
