Lithium disilicate glass ceramic, grown around a single crystalline phase — 400 MPa of biaxial strength wrapped in enamel-like translucency, milled or pressed into veneers and crowns that disappear into natural dentition.
Every Auralis Glass Ceramic ingot belongs to one of three tiers. Choose by how much light the restoration should transmit — and by whether your lab mills or presses.
The light tier. 400 MPa of biaxial strength at near-enamel translucency — for veneers and anterior aesthetics, where a restoration must carry light, not just color.
The masking tier. The same 400 MPa core with greater opacity — it covers discolored stumps and metal posts, for anterior and posterior single crowns, inlays and onlays.
The cast tier. Ingots with excellent flowability; pressed restorations reach 400–470 MPa biaxial — the lost-wax route to ultra-thin veneers and partial crowns that milling cannot reach.
Auralis Glass Ceramic works both ways. CAD/CAM milling turns blocks into restorations within a single visit; heat pressing flows ingots into wax molds, for the thinnest margins in aesthetic dentistry.
HT and LT blocks mount directly in a 5-axis mill. After milling, one crystallization firing at 840–850 °C develops the final strength and translucency — then stain, glaze, done.
Wax up, invest, burnout — then Press ingots flow into the mold under heat and vacuum. The cast ceramic captures sub-0.3 mm veneer margins and a surface texture no bur can cut.

Typical values; the batch inspection report (CoA) ships with the goods.
Ingots are pre-shaded to the VITA classical scale, with multiple translucency levels inside each shade — HT for light, LT for masking. One shade system runs through both milling blocks and press ingots.
A high-strength glass ceramic variant — 800 MPa class, approaching zirconia territory while keeping glass-ceramic bonding — is under development and subject to validation. Ask us when a case sits between glass and zirconia.
Shade guides, sample ingots and full crystallization programs are available for partner labs and clinics across Southeast Asia.
