Multilayer PMMA Discs 12–30mm

Multilayer PMMA is a CAD/CAM polymer disc with multiple integrated shade layers that create a gradual transition from cervical to incisal areas. It is designed for more natural-looking temporary and provisional restorations.

They are suitable for temporary crowns, bridges, full-arch provisionals, implant-supported temporary restorations, diagnostic try-ins, mock-ups, and highly esthetic anterior provisional cases.

Multilayer PMMA features a natural shade gradient and requires correct milling orientation. Monolayer PMMA has one uniform shade, offers simpler nesting, and is often selected for everyday temporary cases where cost efficiency and consistency are the priority.

Yes. The cervical and incisal sides must be identified before nesting. Correct vertical positioning helps achieve the intended shade transition in the final restoration.

Position the cervical area toward the darker layer and the incisal area toward the lighter or more translucent layer. The exact nesting position should be adjusted according to restoration height and the desired esthetic result.

No. Multilayer PMMA is milled directly and does not require sintering or crystallization. After milling, the restoration can be finished and polished.

Use sharp PMMA-compatible burs and a milling strategy designed for resin materials. Worn burs may increase heat, surface roughness, and chipping around thin margins.

The number of restorations depends on the disc thickness, restoration size, nesting strategy, and spacing between units. A 98mm disc can typically accommodate multiple single units or several bridge and full-arch cases, depending on the design.
