Description
KeyDenture Base
Overview
KeyDenture Base is Keystone's high-impact 3D-printable denture Base resin — engineered to bring the lifelike gum esthetics of the Diamond D PMMA family into a digital workflow. The four available shades match the four most-requested Diamond D pinks: Original, Dark Veined, Chroma Essence, and Light Reddish Pink. TPO-free chemistry (only TPO-L) for a cleaner regulatory profile.
Designed for the lab that wants to print finals, not just try-ins. 2000-3000 MPa flexural modulus on the ISO 20795-1 method, >50% strain at break, and a 1.9-2.5 MPa·m½ stress intensity factor that puts it in the high-impact denture Base category — flexible enough not to fracture, rigid enough to hold occlusion.
Why Labs Specify It
Original, Dark Veined, Chroma Essence, Light Reddish Pink.
ISO 20795-1 flexural modulus — high-impact denture Base envelope.
ASTM D638-14 elongation — flexible without brittle fracture.
ISO 20795-1 stress intensity factor — the fracture toughness number that matters.
Engineered Features
- Diamond D Shade HeritageThe four available pinks match the most-requested shades from Keystone's Diamond D PMMA line — the same gum esthetics labs and patients already trust, now in a digital workflow.
- High-Impact Engineered ChemistryFlexural modulus 2000-3000 MPa with strain at break >50% — the rare combination of stiffness and toughness that defines a high-impact denture Base.
- TPO-Free FormulationContains only TPO-L. Cleaner regulatory profile than legacy TPO-containing photopolymers, addressing recent ECHA developments.
- Fast-Print Viscosity1500-1900 cP at processing temperature lets the resin flow into thin gingival contours without sacrificing layer accuracy.
- Cross-Platform CompatibleDesigned for DLP, LCD, and LED printers operating at 385-405 nm wavelengths — the broadest ecosystem fit in the KeyPrint denture line.
Why It Sells
- Lifelike gingival estheticsFour shades cover the realistic patient population — not generic flat pink.
- Print finals, not just try-insHigh-impact properties qualify it as a true denture Base, not a temporary.
- TPO-free is the futureGet ahead of the regulatory curve.
- Pairs with KeyDenture Try-InTry-in to final, same brand, same workflow.
- Fast viscosity, fast print1500-1900 cP keeps build times tight on production runs.
Clinical Applications
Complete upper or lower bases with realistic gum esthetics.
Removable partial denture Base sections for hybrid cases.
Hybrid prostheses where the Base needs flex without fracture.
Print and deliver immediately post-extraction with healing-shade choice.
Digital remake of fractured PMMA bases.
Approved try-in becomes printed final in matching shade.
What Makes It Different
Most 3D denture Base resins fall into one of two traps: too rigid (fractures under bite load) or too flexible (loses occlusion in months). KeyDenture Base lives in the engineered middle — the 2000-3000 MPa modulus paired with >50% elongation gives the high-impact behavior the indication actually requires. The fact that it ships in four Diamond D shades (not one sad medium pink) is what closes the case with the patient.
And TPO-free is a real thing. ECHA classifications around TPO-containing resins are tightening across the EU. Getting ahead of that with a TPO-L-only formulation today means no scramble when distribution restrictions land.
