Find the Right Zirconia Block for Every Indication

Pricing depends on zirconia series, disc size, thickness, shade, order quantity and OEM requirements. Standard 95 mm and 98 mm zirconia discs are available for wholesale orders, while custom packaging, private labeling and non-standard sizes are quoted separately. Contact KEKR for the current price list and volume pricing.

These terms all refer to the same type of material — a pre-sintered ceramic unit designed for CAD/CAM dental milling. "Zirconia block" is the general industry term. "Zirconia disc" specifically describes the round disc format (95mm, 98mm, AG) used in most milling machines. "Zirconia blank" is common in the US and European markets for the unsintered or pre-sintered unit before milling. "Zirconia puck" is informal slang used by dental technicians. KEKR offers all formats.

Gradient zirconia — also called multilayer zirconia disc — incorporates varying Yttria content within a single block. The cervical zone maintains 3Y-TZP level strength (800–1,300 MPa) for structural integrity, while the incisal edge transitions to 5Y-TZP translucency (up to 57%) for lifelike aesthetics. This means a single disc type can serve both anterior and posterior restorations, simplifying your lab's inventory and CAD/CAM workflow.KEKR offers multilayer zirconia options including Aurora 4D, Aurora 4DX and Neon 5D, with different strength and translucency gradients for a wide range of indications.

KEKR zirconia blanks are open-system compatible with all major dental milling machines, including Dentsply Sirona inLab, Roland DWX, Amann Girrbach Ceramill, vhf, Zirkonzahn, Imes-icore, Wieland, and Yenadent. All discs are available in 95mm, 98mm, and AG formats. If you use a system not listed, please contact us — we support custom sizes for OEM partners.

Each zirconia generation (3Y, 4Y, 5Y) requires its own specific sintering protocol. Using the wrong temperature curve is the most common cause of cracking, reduced translucency, and compromised strength. KEKR provides detailed, product-specific sintering curves with every order. Common failure causes include heating too quickly (causing surface-to-core stress), insufficient hold time (incomplete densification), and furnace contamination (discoloration). Our technical team is available to troubleshoot any sintering issue.

Yes. The Neon 5D and Aurora 4D series are specifically engineered for anterior esthetics with up to 57% translucency and natural multilayer color gradients — comparable to natural tooth structure. The SHT series (47% translucency) is also suitable for both anterior and posterior crowns. For anterior-only cases requiring maximum translucency, the 5Y-TZP incisal region of gradient discs provides an ideal match.

Standard zirconia blocks in regular sizes and shades typically ship within 1–3 business days. For OEM or custom orders (private labeling, non-standard sizes, custom shades), lead time is 7–15 days depending on volume and complexity. KEKR maintains a production capacity of up to 2,000 pieces per week, ensuring reliable supply for high-volume labs and distributors.

For best results, KEKR recommends a two-step approach: submerging (dipping) for the core base shade to achieve uniform color and natural value; followed by surface staining with Auraera Stain & Glaze Paste for final shade layering and surface characterization. Research shows the submerging technique minimizes value increase, preventing the restoration from appearing artificially bright. Surface glazes then allow technicians to achieve lifelike natural aesthetics.

Yes. KEKR provides full OEM and ODM services for zirconia blocks, including custom branding, private labels, custom packaging, and non-standard disc sizes. We work with distributors and dental supply companies across 40+ countries. Contact us to discuss minimum quantities, customization options, and pricing for OEM partnerships.
