New Chairside Zirconia Empowers Dentists for Same-Day Restorations

Dental professionals now have a new solution at their fingertips with the introduction of Chairside Zirconia Powered by Roland DGA. This innovative product, fully compatible with the DGSHAPE DWX-42W Series wet-milling solutions, is set to transform the landscape of dental restorations by enabling same-day chairside zirconia restorations through a streamlined workflow of prep, scan, mill, and seat, according to a press release from Roland DGA.

Available immediately through authorized Roland DGA dental resellers, Chairside Zirconia aims to redefine the possibilities for clinical dental professionals. Diverging from conventional monolithic dry-milled zirconia materials, this product boasts an exclusive 3-layer gradient design (25% Incisal, 25% Transition, and 50% Dentin), providing enhanced restorative esthetics with natural translucency, per the press release. This design is achieved without compromising the optimal zirconia strength properties vital for durable dental restorations.

Said to be one of the most significant advantages of Chairside Zirconia is its multi-layered composition, eliminating the need for sintering or additional finishing. This means no requirement for a sintering or ceramic oven, simplifying the process for dental practitioners. With an average flexural strength of 500 MPa without firing, Chairside Zirconia is said to outperform traditional lithium disilicate milling blocks, which only achieve an average of 364 MPa after firing and crystallization.

Moreover, Chairside Zirconia's coarse microstructure, combined with its fracture toughness and low scratch hardness, facilitates superior milling capabilities and results. Clocking in at approximately 4.0 µm, nearly 4 times greater than the average traditional zirconia milling puck, its specific particle structure and density allow it to be designed specifically for wet-milling.

Roland DGA’s Dental Marketing Manager, Lisa Aguirre, expressed excitement in the press release about the product's potential impact on dental practices. "Chairside Zirconia is a revolutionary product that offers significant advantages for clinical dental professionals. The unique qualities of this material, along with the minimal finishing time required, make same-day zirconia restorations possible, without compromising strength or esthetics."

Chairside Zirconia is suited for single-unit, anterior, and posterior restorations, and is available in various shades and milling block sizes. It is seamlessly compatible with Roland DGA’s DGSHAPE DWX-42W Series Chairside wet-milling solutions and ZGB-125D, ZGB-50D, ZGB25D, and ZGB2-75D milling tools. For those eager to embrace the technology, a Chairside Zirconia Powered by Roland DGA “Starter Kit” is on offer, including zirconia blocks in 2 different shades, 3 ZGB milling tools, and Polishing Paste.
