A Novel Polymerizable Amine Co-initiator for Dental Application

The invention involves a tertiary amine that can be used as both a co-initiator and co-monomer for dental applications. When used as co-initiator, it prevents amine leaching from resulted polymers; when used as co-monomer, it increases relative crosslinking density of polymers. The current invention indicates that conversion of monomer to the polymer is extremely efficient and comparable to commonly used photo-initiators. It prevents amine leaching from the polymers compared to current art in the field. The rate of conversion is decreased compared to current art in the field which may lead to decreased polymerization shrinkage. The compound of the invention is used in conjunction with two other compounds widely used in the dental polymer field. The system is irradiated with visible light and the system polymerizes and hardens to form a material suitable for dental applications.

APPLICATIONS: 

  • dentin cement
  • adhesive or aesthetic composite restorative
  • applicable to any field in which a polymeric substance that decreases polymerization shrinkage and prevents amine leaching might be useful

BENEFITS: 

  • prevents amine leaching from resulted polymers.
  • forms with a comparable degree of conversion as known co-initiators.
  • slower kinetics of the current invention might reduce the polymerization shrinkage.
