Denture Fixative: Corega Fixative Science and Formulation

Dual polymer system

Denture fixatives can help stabilise, secure and maintain denture performance.3,4

Corega fixative dual polymer system consists of two ingredients: carboxymethyl cellulose (CMC) and Poly(Methylvinylether/maleic acid) Sodium-Calcium Mixed Partial Salt8.

  • Two polymers are activated on contact with saliva, expand and cross-link to create an elastic polymer network
    • This elastic network can resist both tensile forces and shear stresses
  • Increasing both retention and stability of the denture2

Corega helps seal and protect against food entrapment

Corega fixative sealing action helps reduce food entrapment between the denture and mucosa by 74%.*5

Maintaining denture performance

The Corega denture fixative dual polymer system is designed to maintain denture performance when patients need it the most.
