Xthetic® prime extra

Hightech denture base resin with extended plastic phase

Castable high-tech PMMA resin for the most precise fabrication of removable or fixed dentures using the injection technique. With extended plastic phase.

This high-quality denture resin for complete and partial dentures can be processed with a considerably reduced amount of monomer compared to commercially available autopolymers and is therefore characterized by a high fitting accuracy due to minimal shrinkage, an extremely homogeneous surface and a very low residual monomer content.

Indications

  • Completion of framework dentures
  • Fabrication of full dentures using the injection technique
  • Partial or total relinings (indirect method)
  • Additions and repairs

Product features

  • very good flowability, despite reduced monomer content
  • therefore optimal mucosa compatibility, due to less residual monomer
  • minimal shrinkage, therefore very high fitting accuracy
  • homogeneous surface, very low plaque susceptibility
  • easy finishing and polishing
  • also perfectly suitable for implant work
  • physiological shades and absolute color stability
  • Cadmium free
  • evaluated and certified biocompatibility

Mixing ratio:
10g of powder with 4g of liquid
