Polyetheretherketone discs for the metal-free side of the lab — framework, denture and provisional tiers that mill dry, polish in minutes and cushion the bite with an elastic modulus close to natural bone — far below metal.
Every Auralis PEEK disc belongs to one of three tiers. Choose by what the restoration must do — carry a framework, become the gingiva, or hold the place until the definitive arrives.
The framework tier. A millable replacement for cast metal in removable partial dentures — feather-light, and a metal-free framework option for patients with metal sensitivities (material data on file) — with an elastic modulus close to natural bone, far below metal, that cushions every bite.
The denture tier. Pink-shaded discs for denture bases and telescopic work — monolithic gingiva that mills thin, stays dimensionally stable and never asks for a metal subframe.
The provisional tier. For temporary abutments and provisional crowns — mills clean to the margin, polishes to a high gloss in minutes and seats without firing or light-curing.
A cast framework is rigid by nature; PEEK is forgiving by design. It weighs a fraction of CoCr, contains no allergenic metals and flexes microscopically under load — sharing force with the ridge instead of dumping it on the abutments.
| Aspect | Auralis PEEK | Cast framework |
|---|---|---|
| Weight | ≈ 1.3 g/cm³ — feather-light | ≈ 8 g/cm³ (CoCr) |
| Biocompatibility | Metal-free · no allergenic metals | May contain Ni / Co |
| Aesthetics | Natural · white · pink, no gray show-through | Metal clasps can show |
| Elastic cushioning | Modulus ≈ 3–4 GPa — close to natural bone | ≈ 200+ GPa — fully rigid |
Typical values for dental PEEK and CoCr cast alloys, shown for comparison.
| Property | Value |

Typical values for dental PEEK; batch certificates ship with every disc.
Three shades cover the polymer's whole working range — natural and white for frameworks and provisionals, pink for anything that plays the role of gingiva.
PEEK is on the Mill 5X Dry material list — from disc to finished framework in one dry, dust-extracted pass, nested in Auralis Studio.
Sample discs in natural, white and pink — plus milling parameters for the Mill 5X Dry — are available for partner labs and clinics across Southeast Asia.
