From temporary to denture tooth – GR-17.1 lt is the powerhouse of the GR-17 series.
The resins of the GR-17 series are biocompatible materials for the additive manufacturing of provisional crowns and bridges. GR-17.1 temporary lt offers convincing mechanical properties with a modulus of elasticity of over 5,000 MPa (ISO 10477:2003) and a flexural strength of 112 MPa (ISO 4049) – also suitable for long-term temporaries.
In combination with the denture base materials GR-14.1 and GR-14.2 denture HI, GR-17.1 lt serves as the tooth material for cost-effective, highly aesthetic digital full dentures. As an official exocad reseller, Dentoo supports you with seamless integration into your CAD workflow – from the software licence to the validated print profile.
