Dental PEEK blocks are CAD/CAM milling materials used in dental laboratories for frameworks, temporary restorations, denture bases, partial denture components, and related prosthetic work. Available formats may include discs, blocks, and blanks for open milling systems. Common options include different diameters, thicknesses, shades, and material grades, depending on the intended laboratory workflow. Key specifications to compare are size, color, density, flexural strength, milling system fit, indication range, and finishing requirements.
