Denture Base Resin, Autopolymer

Denture Base Resin, Autopolymer. Acrylic resin for the manufacture of removable or fixed dentures by using the pouring technique.

Indications

  • Completion of framework dentures
  • Casting of complete dentures
  • partial or total relinings (indirect method)
  • Additions and repairs

Product features

  • universal use
  • also perfectly suitable for implant works
  • very good flow ability
  • ideal mucous membrane compatibility due to very low amount of residual monomer
  • minimum shrinkage
  • homogenous surface, high plaque resistance
  • easy burring and polishing
  • physiological shades and absolute color stability
  • Cadmium free
  • evaluated and certified biocompatibility

Mixing ratio:

10g of powder with 4-5g of liquid

Processing times:

Swelling phase: approx. 30 sec
Pouring phase: approx. 3 min
