NobilCam GM3D multilayer zirconia disc – 98.5 x 18mm, shade C4

The NobilCam GM3D disc in shade C4 at a 18mm working height is a pre-shaded, multilayer zirconia blank engineered for open-architecture CAD/CAM milling. Built for highly demanding monolithic esthetic cases where natural translucency, lifelike vitality and seamless shade integration are the priority. Specialized STG layering technology reproduces the multi-directional light dynamics and depth of natural dentition with remarkable batch-to-batch consistency.

shade C4 represents the darkest greyish value in the range, making this disc the natural selection for the most chromatic grey cases, typically posterior and full-coverage. 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 700-1200 MPa across the layered profile
• Translucency range of 45%-57%, tuned for maximum esthetic depth and light dynamics
• pre-shaded to VITA-equivalent C4 — 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 C4 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

Most multilayer zirconia compromises esthetics to protect strength. The GM3D gradient is Built the other way around: the STG layering process lays down a multi-directional light-scattering profile so the disc reads with the depth and vitality of natural enamel rather than the flat, monochrome look that gives monolithic zirconia away. in shade C4 that matters most in the incisal third, where the darkest greyish value in the range has to fade into translucency without a visible line. at 18mm you have enough vertical stock to nest the restoration so the gradient lands exactly where the anatomy needs it.

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, GM3D sits at 700-1200 MPa and 45%-57% translucency, while MM-4D sits at 800-1300 MPa and 43%-55% — choose GM3D when the case calls for maximum esthetic depth and light dynamics.

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.
