NobilCam MM-4D multilayer zirconia disc – 98.5 x 18mm, shade A2

The NobilCam MM-4D disc in shade A2 at a 18mm working height is a pre-shaded, multilayer zirconia blank Engineered for open-architecture CAD/CAM milling. Engineered as a high-performance universal zirconia that holds an ideal equilibrium between mechanical strength, rich esthetics and laboratory productivity across every indication. It delivers the structural security required for long-span restorations and complex full-arch implant frameworks while maintaining excellent milling stability and predictable sintering shrinkage.

shade A2 represents a light reddish-brown value and the most universally requested shade, making this disc the natural selection for everyday anterior and posterior restorations across most adult patients. at 18mm it is dimensioned for longer-span bridgework and cases with pronounced vertical dimension — clearance for extended spans without nesting compromises.

Key Features

• multilayer gradient structure with a continuous chroma and translucency transition from cervical to incisal — no visible layer banding after milling
• Flexural strength of 800-1300 MPa across the layered profile
• Translucency range of 43%-55%, tuned for structural security across the full indication range
• pre-shaded to VITA-equivalent A2 — no dipping or infiltration step required
• 98.5mm outer diameter with a standard stepped mounting flange for open-system milling units
• 18mm usable working height, providing clearance for extended spans without nesting compromises
• Consistent, predictable sintering shrinkage factor supplied on every disc label and batch certificate
• Homogeneous grain structure for clean margin definition and low chipping at thin cross-sections

Key Selling Points

• Removes the shading bench step entirely — mill, sinter, glaze, deliver
• shade A2 arrives production-ready, eliminating the batch-to-batch colour drift that manual infiltration introduces
• Longer-span bridgework and cases with pronounced vertical dimension are covered by this single height, reducing the number of disc heights a laboratory must hold
• Full 19-shade VITA-equivalent range plus three bleach shades available across the line, so a laboratory can standardise on one material system
• open-architecture format — no proprietary holder, licence key, or system lock-in
• Shipped direct to the laboratory, protecting turnaround on rush cases

What Makes This Unique

The MM-4D formulation refuses the usual trade-off between strength and appearance. at 800-1300 MPa it carries long-span and implant-supported work that softer esthetic zirconia cannot, while still holding 43%-55% translucency so the result does not read as an opaque framework. in shade A2, which is a light reddish-brown value and the most universally requested shade, that combination lets one material serve both the anterior esthetic case and the posterior load-bearing unit. The 18mm height extends that reach to longer-span bridgework and cases with pronounced vertical dimension.

How It Compares

Against a conventional single-layer pre-shaded blank, this disc removes the flat optical transition that forces technicians to compensate with surface stain. Against a manually infiltrated white blank, it removes the drying and dipping cycle and the shade variance that comes with it. Within the NobilCam line, MM-4D sits at 800-1300 MPa and 43%-55% translucency, while GM3D sits at 700-1200 MPa and 45%-57% — choose MM-4D when the case calls for structural security across the full indication range.

Technical Specifications

Compatibility

Fits open-architecture dental milling machines that accept a 98.5mm stepped-flange disc, including the widely used 4-axis and 5-axis laboratory platforms. Nesting and sintering parameters are configured in the laboratory CAM software using the shrinkage factor printed on the disc label. Verify that the milling unit clears a 18mm blank height before ordering this variant.
