TRINIA CAD/CAM discs and blocks are composed of a multi-directional interlacing of fiberglass and resin in several layers. TRINIA is intended to be used by dental technicians and dentists for making copings, substructures or frameworks for permanent and transitional anterior or posterior crowns, bridgework, and substructures that can be either cemented or uncemented restorations, such as telescopic restorations.


Dentists and technicians are looking for alternatives to metal substructures. TRINIA is the CAD/CAM solution for metal-free restorations.

Benefits include
  • Lightweight
  • Durable and resilient
  • No firing required
  • Unique mechanical properties with high flexural and compressive characteristics
  • Biocompatible
  • Adjustable
