New Chairside Zirconia Powered by Roland DGA – fully sintered zirconia CAD/CAM milling blocks designed for use with the company’s DGSHAPE DWX-42W Series wet-milling solutions – make same-day chairside zirconia restorations a reality with a simple prep, scan, mill, and seat workflow.

Available now through authorized Roland DGA dental resellers, Chairside Zirconia is a real game changer for clinical dental professionals. Unlike traditional monolithic dry-milled zirconia materials, it boasts an exclusive 3-layer gradient design (25% Incisal, 25% Transition, and 50% Dentin) for ideal restorative esthetics with natural translucency, while maintaining optimal zirconia strength properties.

With its multi-layered composition, Chairside Zirconia does not require sintering or additional finishing, therefore there is no need for a sintering or ceramic oven. It boasts an average flexural strength of 500 MPa without any firing, compared to the 364 MPa average for traditional lithium disilicate milling blocks after firing and crystallization. In addition, Chairside Zirconia is approximately 4.0 µm, which is nearly four times greater than the average traditional zirconia milling puck. Its coarse microstructure combined with exceptional fracture toughness and low scratch hardness allows for superior milling capabilities and results. Plus, unlike traditional zirconia, Chairside Zirconia is designed for wet-milling due to its unique particle structure and density.

“Chairside Zirconia is a revolutionary product that offers significant advantages for clinical dental professionals,” said Roland DGA’s Dental Marketing Manager, Lisa Aguirre. “The unique qualities of this material, along with the minimal finishing time required, make same-day zirconia restorations possible, without compromising strength or esthetics.”

Perfect for single unit, anterior, and posterior restorations, Chairside Zirconia is offered in a variety of shades and milling block sizes. It is compatible with Roland DGA’s DGSHAPE DWX-42W Series Chairside wet-milling solutions and ZGB-125D, ZGB-50D, ZGB25D, and ZGB2-75D milling tools. A money-saving Chairside Zirconia Powered by Roland DGA “Starter Kit,” which includes zirconia blocks in two different shades, three ZGB milling tools, and Polishing Paste, is also available.
