Multilayer zirconia discs engineered around a single spectrum of light — translucency rising from 46% to 57% between cervical and incisal, strength graded in the opposite direction, so one disc mills a restoration with no staining liquid needed before sintering.
Every Auralis Zirconia disc belongs to one of three tiers. Choose by where the restoration sits — and by how much light it needs to let through.
The light tier. 49% translucency for restorations that live in the smile line — veneers, inlays and anterior crowns, where light matters more than load.
The gradient tier. Six layers shift from a 46% cervical base to a 57% incisal peak, strength graded in reverse from 1050 to 700 MPa — one disc, no staining liquid needed before sintering, no guesswork. The Flash variant sinters in just 40 minutes.
The strength tier. 1200 MPa for the posterior load zone — long-span bridges, frameworks and copings that carry the bite, so Lumen and Multi don't have to.
In a Multi disc, opacity and strength live at the cervical end; translucency rises toward the incisal edge. The gradient is built into the powder itself — pressed, not painted — so it survives milling, sintering and years in the mouth.
Two different ways of carrying light: Lumen holds 49% translucency uniformly through the whole disc, while in a Multi disc the 57% maximum is a local value, reached only at the incisal end of the gradient.

Typical values; the batch inspection report (CoA) ships with the goods.
Pre-shaded in the disc to the VITA® classical scale, plus a three-step bleach range. Multi discs carry the shade through every layer — cervical chroma to incisal light.
Indication depends on material tier and connector design.
| Program | Cycle | Peak |
|---|---|---|
| Standard — all tiers | Conventional | 1450–1530 °C |
| Flash — Multi only | 40 min | 1530 °C |
Flash cycles require an Auralis Sinter high-speed furnace with MoSi₂ elements. Full firing curves ship with every disc.
Shade guides, sample discs and full sintering curves are available for partner labs and clinics across Southeast Asia.
